Introduction: Eosinophilic skin diseases encompass a broad spectrum, including Wells syndrome, which is characterized by histological findings of eosinophilic infiltration in the dermis. The etiology and pathogenesis of Wells syndrome are still unknown, but it has been reported that insect bites, infections, and medications can act as triggers. Fungal infections are common in clinical practice; however, when they are recurrent, have atypical characteristics, or are resistant to treatments, they must be recognized as potential triggers for hypersensitivity reactions such as Wells syndrome. Case Presentation: We present the clinical and histopathological characteristics of a case in which Wells syndrome was associated with a fungal infection. Conclusions: Wells syndrome is a rare skin disorder with polymorphic manifestations, making diagnosis challenging in clinical practice. Therefore, a high index of suspicion is required, and blood tests and skin biopsy are necessary to confirm the diagnosis. [ABSTRACT FROM AUTHOR]

Introduction: Many conditions included under figurate erythemas have similar clinical appearance which makes diagnosis difficult. Among these, eosinophilic annular erythema (EAE) is a rare, uncommon, underreported entity in the pediatric population. Case Report: Herein, we report an 11-year-old boy who presented with asymptomatic recurrent, erythematous-edematous annular plaques with central hyperpigmentation. Discussion: Review of the literature shows scarce reporting of such cases globally and none from India. Clinicopathological findings of our case, suggest that eosinophilic annular erythema is a distinct entity rather than a type of Wells' syndrome. [ABSTRACT FROM AUTHOR]

AIM: In this study, we aimed to review the diagnostic approach to eosinophilic cell renal neoplasms by light microscopy and immunohistochemical techniques. METHOD: In this study 23 of these tumors were eosinophilic variant classic RCC, 15 eosinophilic variant papillary RCC, 13 eosinophilic variant chromophobe RCC and 13 oncocytoma cases. These tumors were immunohistochemically treated with CK7, CD117, EpCAM, Vimentin, RCCm (Renal cell carcinoma marker) and GST-a. RESULTS: In our study, contrary to the general literature on Vimentin, 65.2% negativity was found in our patients with eosinophilic variant classic RCC. However, when compared with other tumor types in our study, vimentin expression was highest in eosinophilic variant classical RCC with 34.8%. Statistically; RCCm, GST-a, EpCAM, CD117, CK7 were found to be significantly associated with tumor types, while no significant relationship was found between Vimentin and tumor types. RCCm positivity and CK7 and CD117 negativity were in favour of eosinophilic variant classical RCC, EpCAM, CK7 and CD117 positivity and Vimentin, GST-a and RCCm negativity supported eosinophilic variant chromophobe RCC, CK7 and RCCm positivity and CD117 and GST-a negativity were found in favour of eosinophilic variant papillary RCC. CD117 positivity and Vimentin, CK7 and GST-a negativity were found to support oncocytoma. CONCLUSIONS: The panel with RCCm, GST-a, EpCAM, CD117, CK7 will contribute to the differentiation of eosinophilic cytoplasm renal tumors that cannot be determined by morphological fi ndings and to reach the correct diagnosis (Tab. 3, Fig. 4, Ref. 54).

Eosinophilic dermatoses encompass a broad spectrum of diseases of different etiologies hallmarked by eosinophilic infiltration of the skin and/or mucous membranes, with or without associated blood eosinophilia. The wide range of dermatological manifestations of this spectrum, including nodules and plaques, pustules, blisters, ulcers, and urticarial lesions, is reflected in a non-univocal classification system. We identified six groups of eosinophilic dermatoses based on the predominant anatomic level of involvement: (1) epidermal; (2) of the dermal–epidermal junction; (3) dermal; (4) of the hypodermis and muscle fascia; (5) of the pilosebaceous unit; and (6) vascular/perivascular. We review clinicopathologic features and management of diseases belonging to each group, particularly: (1) pemphigus herpetiformis and atopic dermatitis as prototypes of the epidermal group; (2) bullous pemphigoid as prototypic eosinophilic dermatosis of the dermal–epidermal junction; (3) eosinophilic cellulitis (Wells syndrome), hypereosinophilic syndromes, Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome, eosinophilic dermatosis of hematologic malignancy and chronic spontaneous urticaria as paradigmatic dermal eosinophilic dermatoses; (4) eosinophilic fasciitis as an eosinophilic dermatosis with predominant involvement of the hypodermis and muscle fascia; (5) eosinophilic pustular folliculitis as a model of the pilosebaceous unit involvement; and (6) granuloma faciale, angiolymphoid hyperplasia with eosinophilia, and eosinophilic granulomatosis with polyangiitis, belonging to the vascular/perivascular group.

It discusses the various topics discussed in the issue including stigmata, dermatitis, and Wells syndrome.

Eosinophilic annular erythema (EAE) is a rare entity of unknown etiology that is possibly related to a hypersensitivity reaction and presents as annular erythematous plaques with tissue eosinophilia. It is classified as a figurate erythema with a controversial relationship to Wells syndrome (WS) in the literature, where it is generally considered a separate entity or subset based on clinical and histopathologic differences. EAE typically presents with recurrent, erythematous, arcuate, and annular plaques on the trunk and proximal extremities. The course of the disease is often chronic, recurrent, and relapsing. Responses to treatment are variable but are typically best with systemic steroids and antimalarials. We report a patient refractory to other therapies who had a striking response to dapsone.

OBJECTIVE: To describe the clinical and histologic features of acute erythroderma in dogs with gastrointestinal disease. DESIGN: Retrospective case series. ANIMALS: 18 dogs with erythroderma and gastrointestinal disease. PROCEDURES: Medical records and biopsy specimens were reviewed. Information collected from medical records included signalment, clinical signs, physical examination and diagnostic test results, treatment, and outcome. The Naranjo algorithm was used to estimate the probability of an adverse drug reaction for each dog. RESULTS: All dogs had an acute onset of erythematous macules or generalized erythroderma. Histologic features of skin biopsy specimens had 3 patterns representing a progressive spectrum of inflammation. Most dogs had vomiting (n = 17) and hematochezia (10). Signs of gastrointestinal disease became evident before, after, or concurrent with the onset of skin lesions in 10, 3, and 5 dogs, respectively. Inflammatory bowel disease, pancreatitis, and adverse food reaction were diagnosed in 5, 3, and 3 dogs, respectively. The cause of the gastrointestinal signs was not identified for 8 dogs. Eight dogs had a Naranjo score consistent with a possible adverse drug reaction. Treatment of skin lesions included drug withdrawal (n = 15), antihistamines (16), and corticosteroids (14). Signs of gastrointestinal disease and skin lesions resolved at a mean of 4.6 days and 20.8 days, respectively, after onset. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicated acute erythroderma may be associated with > 1 gastrointestinal disease or an adverse drug reaction in some dogs. Recognition of the clinical and histologic features of this syndrome is essential for accurate diagnosis. [ABSTRACT FROM AUTHOR]

Eosinophilic cellulitis is an uncommon, inflammatory and chronic disorder of unknown etiology. Corticosteroids are currently considered as the first-line treatment but they are not without significant disadvantages such as contraindications in steroid-resistant cases and patients with frequent recurrences. We report a patient suffering from Wells' syndrome with a 24-year history of symptomatic and generalized skin lesions. After consultation in our department, treatment with colchicine 1 mg/day was prescribed resulting in large clinical improvement. No side effects have been recorded. To our knowledge, this is an original disease approach. Although small, our clinical experience supports the inclusion of colchicine in the drug armamentarium when treating patients suffering from Wells' syndrome. Indeed, its excellent safety profile makes it very attractive for patients with frequent recurrent episodes who need secure options for the medium- and long-term disease control.

Mott cells are a variant form of plasma cells in humans and laboratory animals. This report describes the morphological characteristics of Mott cells observed in a 33-week-old female CB6F1-Tg rasH2 mouse. Microscopically, a large number of round cells with abundant eosinophilic globules, which were variable in size, were observed in the spleen and were densely distributed in the red pulp adjacent to the marginal zone. A few similar cells were present in the submandibular lymph node and bone marrow. Neither systemic nor local chronic inflammatory changes were seen in this animal. These cells were positive for mouse immunoglobulins. Ultrastructurally, the dilated rough endoplasmic reticulum had a homogenous substances with an intermediate electron density. On the basis of the above findings, these cells were identified as Mott cells. The present lesion is thought to be a spontaneous lesion, an unusual appearance of Mott cells without any associated pathological conditions. [ABSTRACT FROM AUTHOR]

Eosinophilic cellulitis (Wells syndrome) is a rare inflammatory skin disease defined by erythematous, tender, sometimes urticarial plaques, possibly with vesicles and bullae, and granulomatous eosinophilic infiltrates in the dermis. Usually the disease has a benign course with spontaneous remission within a few weeks. Nevertheless, recurrences are quite frequent and may occur for several years. The objective of this study was to review the so far reported treatment options for Wells syndrome in a systematic manner. This systematic review is based on a search on Medline, Embase and Cochrane Central Register for English and German articles from 1970 to 2015. Advices on the treatment of Wells syndrome are limited predominately to case reports or to small case series. There are no randomized controlled trials, and control groups are missing. A variety of treatment options for Wells syndrome were reported including topical and systemic corticosteroids, antihistamines, cyclosporine, dapsone, azathioprine, griseofulvin, doxycycline, minocycline, antimalarial medications, oral tacrolimus/topical tacrolimus, sulfasalazine, interferon alpha and gamma, TNF alpha inhibitors, colchicine and PUVA therapy. As well-designed, randomized controlled trials are missing, no guidelines for the treatment of this disease can be given. Due to the small number of patients and the frequent misdiagnosis of this clinical entity, the aim of this systematic overview is to call attention to this rare condition and to help clinicians to diagnose and treat Wells syndrome effectively. Due to the good prognosis and tendency to resolve, systemic treatment should be limited to cases resistant to local therapy or with widespread lesions. [ABSTRACT FROM AUTHOR]

Mosquito bites are skin irritating reactions, which usually resolve spontaneously without intensive medical care. However, in certain situations, mosquito bites may form a more vicious reaction, sometimes accompanying fever and systemic symptoms. In such cases, the presence of rare hematological disorders, abnormalities in eosinophils and/or association with Epstein-Barr virus (EBV) may underlie. Importantly, hypersensitivity to mosquito bites (HMB), which is characterized by necrotic skin reactions to mosquito bites with various systemic symptoms, is often observed in association with EBV infection and natural killer (NK) cell lymphoproliferative disorder. Exaggerated skin reaction to mosquito bites is also seen in Wells’ syndrome. While strong Th2-skewing immune dysregulation is apparent in the patients, they also show robust CD4 + T cell proliferation in response to mosquito salivary gland extracts, indicating close association between Wells’ syndrome and mosquito bites. Similar skin reaction to mosquito bites is also noticed in certain types of B cell neoplasm, although the role of B cells in this peculiar reaction to mosquito bites is yet to be elucidated. In this review, we will discuss the current knowledge of exaggerated reaction toward mosquito bites seen in conjunction with these unique hematological disorders, and examine the scientific studies and observations reported in previous literatures to organize our current understanding of the pathogenesis of this distinct disorder.

Abstract: A 4‐year‐old boy presented with erythematous vesicular plaques, ulceration, edema, and pruritus on the left foot and ankle 10 days after receiving the tetanus, diphtheria, pertussis, and polio; measles, mumps, rubella, and varicella; and hepatitis A/B vaccines. Biopsy showed eosinophilic infiltrates and flame figures, suggesting Wells syndrome. Patch testing showed a 1+ reaction to neomycin and aluminum hydroxide, with a recall reaction of Wells syndrome of the feet bilaterally. We report a rare case of pediatric Wells syndrome triggered by nonthimerosal vaccine components confirmed by patch testing. [ABSTRACT FROM AUTHOR]

Wells syndrome, part of eosinophilic dermatosis, is characterized by infiltrated plaques with edema and erythema, which resolve without scarring and are accompanied by peripheral blood eosinophilia.

Canine urolithiasis is a common disorder of the urinary tract, characterized by stones located anywhere within the urinary tract, which is mostly encountered in middle-aged to older dogs. Urolithiasis is influenced by familial, congenital and pathophysiological factors including urinary pH, dehydration, urinary infection, anatomical abnormalities and drug administration. A 3 weeks old mixed German Shepherd male puppy with no antecedent clinical signs (sudden death) was submitted to the Pathology Department for necropsy. The animal was suspected of bronchopneumonia ab ingestis due to milk aspiration. Necropsy, cytological and histological exams were performed. Grossly, a large amount of urine was found within the peritoneal cavity (uroperitoneum) secondary to urinary bladder rupture, severe bilateral hydronephrosis and hydroureter, and urethral obstruction with numerous large white to gray calculi varying in size from 2-10mm were identified. The cytological exam showed several large, white to yellow spheroids with radial concentric laminations consistent with leucine crystals. Histologically, the renal tubules were diffusely dilated and contained pale eosinophilic hyaline casts, sloughed necrotic epithelial cells and lamellated concretions of amphophilic radiating structures. A diagnosis of urethral obstruction due to leucine urolithiasis was made, and it was associated with hydronephrosis, hydroureter and urinary bladder rupture. To the best of the authors' knowledge this is the first report of leucine urolithiasis in a dog in Romania. [ABSTRACT FROM AUTHOR]

Wells' syndrome (WS), or eosinophilic cellulitis, is an uncommon inflammatory dermatosis of unknown etiology that typically presents with pruritic cellulitis-like plaques on the extremities. Therefore, WS is often misdiagnosed as bacterial cellulitis due to its similarity in presentation. Here, we report two cases of WS that masqueraded as bacterial facial cellulitis. Under treatment with oral prednisone and/or a combination therapy with levocetirizine and hydroxyzine, both patients showed a dramatic improvement of the skin lesions. These cases highlight the need for clinicians to consider WS in the differential diagnosis when evaluating a patient with facial cellulitis that does not respond to an initial antimicrobial regimen. In addition, our cases suggest that combination therapy with levocetirizine and hydroxyzine may be successfully used as corticosteroid-sparing treatment or to prevent relapse after the discontinuation of corticosteroid treatment. © 2015 S.

A 5-year-old boy was referred because of urticarial flares with angioedema. Antihistamines and systemic steroids were not useful to prevent flares. At examination, at distance of a flare, chronic red-brownish plaques were found on the legs, trunk, and back, resembling granuloma annulare. The skin biopsy showed epithelioid and giant-cell granulomas, elastophagia, and "flames figures" surrounded with many eosinophils. A diagnosis of disseminated granuloma annulare-like variant of Wells' syndrome as described earlier by Caputo was made. A treatment with dapsone was initiated and enabled to stop flares. Wells' syndrome is a rare clinicopathologic entity with a chronic benign course and often misleading clinical presentation. Our case illustrates the clinical polymorphism and benefit of dapsone therapy. [ABSTRACT FROM AUTHOR]

Background We report a case of a 33-year-old man who presented with immunoglobulin (Ig)G4-related disease (IgG4-RD) forming a pseudotumor in the left paratesticular region during oral administration of corticosteroid for Wells syndrome, which involves cellulitis with eosinophilia. Case presentation The patient was introduced to our institution from a private hospital with a 3-month history of asymptomatic left scrotal mass. A 5-cm diameter nodule was palpable in the left scrotum. Tumor lesion in the left paratestis involving the epididymis and spermatic cord was observed on computed tomography and magnetic resonance imaging. Blood testing showed no abnormalities other than a minimal increase in C-reactive protein levels. Urine examination likewise revealed no significant findings. Left radical orchidectomy was performed under a diagnosis of left paratesticular neoplasm suspected as malignant tumor. The tumor was pathologically identified as IgG4-RD of the left paratestis involving the epididymis and spermatic cord. Conclusions We present a first description of IgG4-RD in a patient with Wells syndrome and the ninth case of IgG4-RD in a scrotal organ, and discuss this very rare entity with reference to the literature.

Background: Viliuisk encephalomyelitis (VE) is an endemic neurological disease in Northeast Siberia and generally considered to be a chronic encephalomyelitis of unknown origin actually spreading in the Sakha (Yakutian) Republic. Methodology and Principle Findings: In search for the pathophysiology and causative agent of VE, we performed a cross-sectional study on clinical, serological and neuroimaging data on chronic VE patients during two medical expeditions to three villages within the Viliuiski river basin in the Republic of Sakha in 2000 and to the capital Yakutsk in 2006. The severity of the core clinical picture with predominant sensory ataxia, gait apraxia, lower limb spasticity, cognitive impairment and bladder dysfunction correlated with the degree of MRI findings showing enlargement of inner ventricular spaces as in communicating hydrocephalus. Laboratory studies revealed transient eosinophilia during the preceding acute meningitis-like phase, but no ongoing inflammatory process in the CSF. We found immune reactions against Toxocara canis in the majority of chronic VE patients but rarely in controls (P = 0.025; Fisher's exact test). Histological analysis of subacute to subchronic VE brain samples showed eosinophilic infiltrations with no signs of persistent Toxocara canis infection. Conclusions and Significance: Our data showed that pressure by the communicating hydrocephalus as a mechanical factor is the major pathogenic mechanism in chronic VE, most likely triggered by eosinophilic meningitis. There are no signs for an ongoing inflammatory process in chronic VE. The past eosinophilic reaction in VE might be caused by Toxocara ssp. infection and might therefore represent the first hint for an initial cause leading to the development of chronic VE. Our data provide a framework for future studies and potential therapeutic interventions for this enigmatic epidemic neurological disease potentially spreading in Sakha Republic.

The "Wells syndrome" is a rare inflammatory dermatosis of unknown pathogenesis, clinical polymorph, both the location and the extent of the lesions. This is a skin disease of inflammatory origin, which usually appears in children and adolescents. Has a polymorphic clinical picture, both the location and the extent of the lesions, and for the correct interpretation of diagnostic histopathological lesions required. This entity should be considered in the differential diagnosis of any atypical presentation of cellulite with peripheral eosinophilia, that does not respond to antibiotics. [ABSTRACT FROM AUTHOR]

Background: Wells syndrome is an uncommon inflammatory dermatosis first described in 1971 by Wells. The clinical eruption is characterized by varying morphology and severity and usually follows a relapsing remitting course. The majority of the reported cases are of unknown etiology, drug induced Wells syndrome has rarely been reported. A literature search using MEDLINE was performed. We recorded the features of our case and of the additional cases of drug induced Wells syndrome in the literature. Main observations: Including our case there are 25 cases of drug-induced Wells syndrome reported. Causative drugs include antibiotics, anticholinergic agents, anaesthetics, non-steroidal anti-inflammatory agents, thyroid medications, chemotherapeutic agents, thiomersal containing vaccinations, anti-tumor necrosis factor agents and thiazide diuretics. Conclusions: To the authors knowledge this is the first reported case of drug-induced Wells syndrome from thiazide diuretics. The diagnosis of Wells syndrome is often controversial and we propose a set of diagnostic criteria. [ABSTRACT FROM AUTHOR]

A 10-week old preterm infant boy presented with a pustular eruption of the face and blood eosinophilia. Histology demonstrated eosinophils without predominant follicular involvement. The lesions healed without intervention within 2 months. The presentation was consistent with neonatal eosinophilic pustulosis. We discuss the similarities between cases described in the literature and suggest that this entity affects a unique patient population of preterm infants. [ABSTRACT FROM AUTHOR]

Objective and design: Asthma is associated with eosinophilic airway inflammation and characterized by enhanced airway sensitivity. Interleukin (IL)-5 plays an important role in the pathogenesis of asthma. The involvement of IL-5 receptor-mediated cellular signals in the pathogenesis of a mite antigen-induced chronic asthma model was investigated. Subjects: In this study, 48 female C57BL/6J (WT) mice and IL-5 receptor-deficient (IL-5RKO) mice were used. Treatment: Mite antigen (50 μl) was intranasally administered 13 times to WT and IL-5RKO mice. Methods: Airway hypersensitivity (Mch PC) and specific antigen exposure tests were performed, and lung tissue, bronchoalveolar lavage fluid (BALF), and blood were collected to investigate the asthma pathology and differences in the local pulmonary levels of cytokines and chemokines. Results: Airway sensitivity was enhanced and antigen-specific airway resistance was increased in WT mice. In addition, the number of eosinophils and Th2 cytokine levels in the BALF were increased. In contrast, IL-5RKO mice did not acquire the asthma pathology, such as antigen-specific airway resistance and eosinophilic airway inflammation. Mch PC was significantly correlated with cysteinyl leukotriene levels in WT mice. Conclusion: These findings suggested that both IL-5 induced eosinophils and cysteinyl leukotrienes are involved in the pathology of this mite antigen-induced chronic asthma model.

Background/Objective Eosinophilic annular erythema (EAE) was proposed to describe annular skin lesions associated with tissue eosinophilia, however, its relation to Well's syndrome (WS) remains a source of controversy. We studied a series of patients to increase awareness of this entity and to clarify its relation to WS. Methods A multicentre study in which the clinical records, histological findings, laboratory results, therapeutic responses and follow-up of 10 patients were demonstrated. Results The study included seven women and three men with age ranging from 31 to 54 years. The duration of the disease ranged from 3 to 28 months. All patients showed involvement of trunk and extremities. Early lesions were manifested as erythematous plaques, which progressed to well-developed figurate lesions and ended as large annular lesions with pigmented centre and elevated border. Flame figures were only observed in well-developed and long-standing lesions. Blood eosinophilia was found in all patients with different grades. Associated disorders included chronic gastritis, diabetes mellitus, chronic hepatitis-C virus infection and chronic kidney disease. The disease showed chronic course with high relapse rate and resistance to various therapeutic modalities including systemic steroid alone and in combination with hydroxychloroquine and cyclosporine. Conclusion We believe that EAE is a peculiar clinical variant in the spectrum of WS, which is characterized by a chronic course, resistance to treatment and high relapse rate. The diagnosis and evaluation of this condition need a close monitoring with repeated clinical, histological and laboratory assessment. [ABSTRACT FROM AUTHOR]

Eosinophilic fasciitis is a systemic autoimmune disease that manifests with fibrosing inflammation of the fascia and the surrounding skin, sometimes even muscle tissue is involved. Clinically, the disease manifests as rigid indurations or sclerotization of the skin that may resemble systemic sclerosis. In laboratory tests, elevated levels of ESR, increased C-reactive protein in serum and marked eosinophilia dominate. Autoantibodies are usually negative. Inflammation of the fascia can be best viewed by magnetic resonance imaging, and the diagnosis is confirmed by histological examination. The therapy includes the administration of glucocorticoids. In refractory forms, the combination of glucocorticoids with immunosuppressive agents (methotrexate, etc.) is used. A beneficial effect of infliximab has been described as well.

Wells' syndrome is a rare eosinophilic dermatitis first described 40 years ago, with a wide clinical spectrum and varied histology according to the stage of the cutaneous lesions, associated with numerous endogenous and exogenous factors, including infectious and gastrointestinal diseases. We present the case of a woman with a 10-day history of edematous, itching and recurrent plaques in limbs with pustules in the right cheek, chest, abdomen and hips. Wells' syndrome was diagnosed and the following findings were documented: flame figures in the histological sections, negative immunofluorescence for immune complexes and complement deposits, peripheral blood eosinophilia, and Helicobacter pylori infection confirmed by endoscopy and gastric biopsy. Possible physiopathological mechanisms of a new association with H. pylori are discussed. It may be a coincidence or a possible etiology that should be further investigated. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 47 years old male patient, who was admitted for the evaluation of multiple pruritic erythematous papules on the lower extremities and diagnosed with wells' syndrome with a clinicopathological correlation associated with mantle-cell lymphoma. Topics include clinical examination stated to be unremarkable except for the presence of splenomegaly, and the inflammatory process involved the entire thickness of the dermis as well as the subcutis.

Eosinophilic Cellulitis (Wells Syndrome) is an uncommon inflammatory disease with clinical polymorphism. A thirty-five-year-old female presented with 2 weeks history of gradually progressive and painful erythematous plaque on the right foot. She had already received several types of antibiotic for the cellulitis without improvement. A diagnosis of Wells syndrome was established. Significant improvement was noted after one month of treatment with prednisolone. Awareness of this condition is necessary for early identification and management. [ABSTRACT FROM AUTHOR]

Well's syndrome, in many circumstances, is determined by intensive eosinophilic infiltration into dermal layer with the clinical presentation of erythematous and edematous plaques which can easily be remitted by current corticosteroid therapies. Up to now, different etiologies have been proposed governing Well's pathophysiological procedure. Of note, no evidence of seasonal association has been already reported. A 70-years-old afebrile male presented with a chief complaint of 30-years history of cutaneous manifestations along with non-ulcerated edematous, erythematous plaques and patches, and extensive pruritus confined on both dorsal and palmar surface of upper extremities occurred annually in early summer. We hereby report a case in season-dependent of Well's syndrome occurrence. [ABSTRACT FROM AUTHOR]

Wells' syndrome (WS) is an uncommon inflammatory skin disease which typically presents single or multiple erythematous and edematous urticarial plaques similar to cellulitis. The lesions may evolve into blue-grey morphea-like lesions and may persist for weeks or months. They ultimately heal without scar. Other clinical presentations reported in literature include papular and nodular and, rarely, bullous eruptions. Previously, bullous Wells' syndrome was rarely reported in the literature. Herein, we describe a case of a female patient with bullous Wells' syndrome localized to the upper limbs without any associated disorders. [ABSTRACT FROM AUTHOR]

Eosinophilic cellulitis (Wells' syndrome) is an uncommon inflammatory disease with clinical polymorphism. It is often associated with infectious, allergic or myeloproliferative diseases; however, the exact aetiology is unknown.

The typical skin findings of Wells' syndrome disappeared completely following chemotherapy and autologous stem cell transplantation. [ABSTRACT FROM AUTHOR]

A 69-year-old woman with chronic lymphocytic leukaemia presented with an 18-month history of pruritic, tender, erythematous plaques. The recurrent lesions simulated insect bites and cellulitis, but failed to respond to appropriate treatments. A recent severe flare was associated with markedly elevated inflammatory markers and swelling of the left leg. The swelling settled rapidly with ibuprofen, leaving cellulitis around a small ulcer infected with Staphylococcus aureus and Streptococcus pyogenes. The cellulitis responded to oral flucloxacillin. Subsequent multiple small exaggerated insect bite reaction lesions settled with oral prednisolone. Eosinophilic cellulitis (Wells' syndrome) was considered unlikely based on the lack of a morphoea-like resolution phase, histological lack of flame figures and presence of vasculitis; however, the distinction is probably artificial.

Background Wells' syndrome was first described by Wells in 1971 as a recurrent granulomatous dermatitis with eosinophilia and was later named eosinophilic cellulitis. It is defined by the following criteria. (i) sudden onset of annular or circinate crythematous-edematous patches that rapidly evolve to morphea-like blue-state-colored plaques; (ii) a histological picture usually characterized by the presence of 'flame figures': (iii) non-constant blood hypereosinophilia. Methods We describe the case of a 49-year-old woman who reported the sudden appearance of a few hard, pasty, ovalshaped, reddish-violet, moderately itchy, erythematous-edematous patches on both arms about 2 months before our observation. Results The remote pathologic history showed that the woman have been submitted to quadrantectomy with lymph node dissection followed by cobalt therapy for breast cancer. Based on the pharmacological history intake of drugs was excluded. Routine blood chemistry and instrumental tests did not show any alteration, nor did assays of the main autoantibodies, complement, circulating immunocomplexes, or tumor markers. Conclusions Histologically the picture was compatible with the diagnosis of Eosinophilic cellulitis. Following topical corticosteroid therapy the lesion healed rapidly. It relapsed 2 months later, and was again cured with the same topical treatment. No further relapses were observed in a 1 year follow-up. [ABSTRACT FROM AUTHOR]

Eosinophilic cellulitis (Wells' syndrome) is an uncommon condition of unknown etiology. Wells' syndrome is usually seen in adulthood but very rare in childhood. Although pathogenesis of the disease is not very clear, it is a hypersensitivity reaction developing against a variety of exogenous and endogenous antigenic stimuli. Paraphenylenediamine is a strong allergen frequently used as a temporary henna tattoo, which makes the color darker . Here, a 9-year-old male patient with Wells' syndrome is presented, which developed following a temporary henna tattoo and shown by the patch test sensitivity to paraphenylenediamine.

Abstract: Perivascular epithelioid tumors (PEComa) are uncommon mesenchymal neoplasms demonstrating positivity for muscular and melanocytic immuno-markers. Included in this category are angiomyolipoma, lymphangioleiomyomatosis, and clear cell sugar tumors. Lesions which do not fit into these categories are classified as “not otherwise specified”. We present a case of an incidentally discovered PEComa within inguinal hernia sac contents in a 70-year-old woman. It consisted of spindled and epithelioid cells with bland oval nuclei, small nucleoli and clear to light eosinophilic cytoplasm. There was no atypia or mitoses. The lesion was strongly positive for HMB45 and smooth muscle actin. Pelvic soft tissue and peritoneal PEComas are rarely reported in literature and very little is known about their prognosis. We discuss the immunohistochemistry, differential diagnosis, and pathogenesis of PEComas. [Copyright &y& Elsevier]

Wells syndrome or eosinophilic cellulitis is a rare condition, primarily a disease of adults. It is characterized by edematous and erythematous plaques with violaceous borders persisting for weeks. Here, we describe a rare case of Wells syndrome occurring in a 51-year-old diabetic lady associated with a dental abscess. She was admitted with complaints of recurrent episodes of raised skin lesions on the body for the last two years. Patient also gave history of toothache with swelling of gums on and off since the last 2 years A skin biopsy was done from a raised lesion on the back which was consistent with eosinophilic cellulitis The patient was put on prednisolone 40mg daily along with ranitidine, calcium and oral hypoglycemics. She underwent tooth extraction for recurrent dental abscesses in the dental OPD. Our patient had dental abscess, a known predisposing factor. The association with diabetes mellitus is another unique feature, rarely reported before. [ABSTRACT FROM AUTHOR]

Wells' syndrome is a multifaceted dermatosis with a wide morphological spectrum, ranging from characteristic cellulitis-like erythema and papula to an unusual presentation of vesicles and pustules. The most important elements for diagnosis are erythemal plaques and histological picture of eosinophilic infiltration of the dermis with 'flame figures' (Plotz et al., in Hautarzt 51:182-186, ). Because of its original description as a distinct entity, it has come to be regarded as an abnormal eosinophilic response to a number of causative agents such as herpes simplex virus 2(HSV-2) and toxocara (Ludwig et al., in J Am Acad Dermatol 48:S60-S61, ; Bassukas et al., in Cases J 1:356, ). Concurrence of WS and malignant diseases as colon cancer, trachea squamous carcinoma, nasopharyngeal carcinoma or angioimmunoblastic lymphadenopathy has been reported (Hirsch et al., in J Dtsch Dermatol Ges 3:530-531, ; Renner et al., in Acta Derm Venereol 87:525-528, ). Autoimmune diseases, including Systemic lupus erythematosus (SLE) are multi-system disorders of unknown cause and are commonly characterized by protean cutaneous manifestations. To date, few autoimmne disease was found associated with WS except four previous reports of Churg-Strauss syndrome (CSS) and one case of ulcerative colitis (Fujimoto et al., in Clin Exp Dermatol, ; Sakaria et al., in J Gastroenterol 42:250-252, ). The coexistence of SLE and WS in one patient was not found in literature and our case is the first. Here we described the rare combination and discussed the treatment strategy for this condition.

Wells' syndrome is a rare inflammatory dermatitis. To date, the cause is unknown but it has been associated with a variety of triggers. We present a case of Wells' syndrome with coexisting photosensitivity. [ABSTRACT FROM AUTHOR]

Wells' syndrome, also termed eosinophilic cellulitis, is a dermatologic condition of unknown etiology that occurs as recurrent patches or plaques mimicking infectious cellulitis. Histopathology reveals an eosinophilic infiltrate and characteristic flame figures. Previous reports have associated this syndrome with parasitic infections, arthropod bites, pharmacologic agents, surgery, and hematologic disorders. We present a case report of a patient with Wells' syndrome associated with newly diagnosed ulcerative colitis. The dermatosis erupted concurrently with flares of ulcerative colitis. Furthermore, treatment of the ulcerative colitis led to resolution of the skin lesions. To our knowledge this describes the first association between inflammatory bowel disease and Wells' syndrome and argues for a distinct relationship between the two. [ABSTRACT FROM AUTHOR]

Wells' syndrome is a multifaceted dermatosis with a wide morphological spectrum, ranging from characteristic cellulitis-like erythema and wheals to an unusual presentation of vesicles and bullae. We describe a patient in whom Wells' syndrome presented as an insect-bite-like eruption and was associated with underlying mantle-cell lymphoma. We recommend meticulous investigation of patients diagnosed with Wells' syndrome manifesting as an insect-bite-like eruption. [ABSTRACT FROM AUTHOR]

ABSTRACT We report a patient with Churg–Strauss syndrome (CSS) with asthma, eosinophilia, nasal polyposis and ANCA-associated multisystem vasculitis, who's skin eruption started with erythematous urticarial-plaques followed by haemorrhagic bullae. Histology of the plaques revealed ‘flame figures’ in the dermis with no granulomatous or vasculitic process, consistent with the diagnosis of eosinophilic cellulitis or Wells’ syndrome. The association of CSS and Wells’ syndrome observed in this patient may have a common pathogenesis. CSS may induce Wells’ syndrome by an unknown factor. [ABSTRACT FROM AUTHOR]

Wells’ syndrome (WS) is a rare, recurrent, inflammatory dermatosis of uncertain pathogenesis, although a hypersensitivity response to different stimuli has been postulated. Several cases in association with parasitic infections have been described. We present a patient with WS associated with recurrent giardiasis. The course of the dermatosis was strictly related to the course of the parasitic infection. Both diseases disappeared with antiparasitic treatment. To our knowledge, this association is here reported for the first time. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 45-year-old man with a history of fever and erythema of the extremities, the presence of lymphocytes and eosinophils were detected. It notes the demonstration of blood neutrophilia and the increased C-reactive protein, the impact of coxsackievirus A6 infection, and diagnosis of the patient for Wells' syndrome.

The article discusses the n inflammatory dermatosis called Wells syndrome. It talks about the histopathological findings of the disease. It discusses Neutrophils occurring in the ailment. It discusses the use of omalizumab and corticosteroids in the treatment. It discusses the decreasing cytokines contributing to the treatment.
