Adamantiades-Behçet disease (ABD) is a systemic disease with vasculitis, characterized by recurrent oral aphthosis and ocular, cutaneous, articular, vascular, cardiopulmonary manifestations and it is mainly found in the territories of the antique "silk road". ABD pathogenesis remains unknown although genetic, infectious and environmental factors seem to be implicated in the development of the disease, which is considered an auto-inflammatory condition. COVID-19 infection can present some symptoms, in particular at the level of oral and pulmonary mucosa, which require a differential diagnosis with ABD. Furthermore, the immunological alterations of this disease, and the drugs used for its treatment could influence the infection by COVID-19, and its clinical evolution. Nevertheless, vaccination anti-COVID-19 is recommended in ABD patients. The most commonly used diagnostic criteria for ABD are those established in 2014 by the International Team for the Revision of the International Criteria for BD (ITR-ICBD). Furthermore, criteria for disease severity according to the Overall Damage Index of Behçet's Syndrome (BODI) have recently been proposed in order to quantify the severity of the disease as well as the evolution during follow-up. In ABD patients it is mandatory to investigate on the presence of active/latent tuberculosis, because of the common organ involvement, such as eyes and bowel. ABD has a high morbidity and low mortality, sometimes linked to the rupture of an arterial aneurysm and/or neurological complications. This article is based on a general review on ABD ranging from the history of ABD to possible causes and clinical manifestations. A specific section has been dedicated to the COVID-19 pandemic.

Adamantiades-Behçet's disease (ABD) is a chronic, idiopathic, relapsing immune-mediate disease that may involve multiple organs. It is characterized by recurrent oral and genital ulcers, skin lesions, ocular, gastrointestinal, vascular, neurological and joint involvement. It can lead to significant morbidity and mortality. Due to its heterogeneity in clinical findings and physiopathology, its treatment can be various as ABD manifestations in different organs may differently respond to the same drug. The cornerstone of therapy for inducing remission is systemic corticosteroid, whereas immunomodulatory and immunosuppressive agents such as colchicine, azathioprine, cyclosporine-A, interferon-alpha, and cyclophosphamide are used as steroid-sparing agents and to prevent relapses. For aggressive, refractory or frequently relapsing cases, tumor necrosis factor (TNF) alpha inhibitors (infliximab, adalimumab, etanercept) have been reported beneficial. Herein, we describe our experience of 7 patients treated with TNF-alpha inhibitors with recommendations regarding treatment choice during the COVID-19 era.

Dear Editor, Grover's disease, also known as transient acantholytic dermatosis, is an idiopathic and acquired pruritic eruption of small vesicles and erythematous papules, classically on the central chest. The pathogenesis is not clearly defined, although heat sweating and occlusion have been interpreted as predisposing factors. We describe a case of monolateral acantholytic eruption with blaschkoid distribution in a patient treated with an orthopedic bandage for a shoulder injury. A 53-years-old man was referred to the dermatologic department because of an acute eruption of pruritic, discrete, pinkish grey papulovesicles, developed on the right side of the trunk 14 days after the positioning of an orthopedic bandage for a shoulder injury. This skin eruption followed a multilinear distribution along Blaschko lines (Figure 1, a, b). The medical history was unremarkable. The patient's family history was negative for similar dermatosis. Histopathological analysis showed acantholytic dyskeratosis with suprabasal cleft. A basket weave epidermic pattern with hyperkeratosis was observed, with a perivascular lymphocytic infiltration in the upper dermis (Figure 1, c, d). Given the clinical and histopathological features, a diagnosis of monolateral Grover's disease was established. The patient was treated with topical mometasone furoate 0.1% cream for 3 weeks with clinical improvement. Monolateral blaschkoid distribution in Grover's disease is extremely rare, with only 1 case reported in the literature (1). Two cases of zosteriform distribution have been described (2,3). The exact pathogenesis and the differential diagnosis with linear Darier's disease were the main topics of discussion, while the pathogenesis is still in debate. In our case, it appears that a shoulder bandage can cause an occlusive environment that can elicit the disease (4). Similar conditions were present in a previously described cases of bedridden patients (1). Some authors have postulated that such conditions may act as precipitating factors on a genetically predisposed epidermis (1). In monolateral and localized cases, postzygotic somatic mutations along Blasckho's lines or in dermatomes could be present. It is also important to distinguish this monolateral and blasckhoid Grover's disease from other acantholytic dermatoses. In this case, the differential diagnosis with an eruptive linear Darier's disease is very difficult (5). Histopathological analysis is not useful. Both monolateral and ordinary variants of Darier's disease can be elicited by environmental factors such as heat, sweating, or occlusion. The diagnosis of monolateral blaschkoid Grover's disease was preferred due to the patient's anamnesis (late-onset and no familiar history of similar dermatosis) and the clinical features (sparing of the head, extremities, and flexures). Since only additional genetic analysis could definitively resolve this question, it was performed. No mutation in genes coding the Ca2+ pump using genomic DNA from the patient's white blood cells or from a skin biopsy was found. A clinical anamnestic and genetic correlation is always crucial in these rare and unique acantholytic dermatoses.

Leukemia cutis (LC) is described as cutaneous infiltration by neoplastic leukocytes into the epidermidis, dermis, or subcutis, resulting in clinically various skin lesions. When the infiltrate is characterized by neoplastic granulocytic precursors, LC is defined as granulocytic sarcoma. Multiple, erythematous, and infiltrated papules and nodules localized on the legs, arms, and trunk are the most common clinical presentation. Here we report a case of granulocytic sarcoma in a patient with a previous diagnosis of acute myeloid leukemia currently in hematological remission.

We report the occurrence of Staphylococcus lugdunensis cutaneous infection with sporotrichoid distribution of the left lower limb of a 60-year-old man. Recent studies have confirmed that Staphylococcus lugdunensis is a significant pathogen in causing skin and soft tissue infections that usually manifest in abscesses, surgical wound infections, and cellulitis. It used to be considered a skin commensal bacteria, but if unrecognized it can lead to fulminant endocarditis, meningitis, skin abscesses, peritonitis, and spondylodiscitis.

Background: Borrelia burgdorferi has been associated with primary cutaneous B-cell lymphoma, in particular with cutaneous marginal zone B cell lymphoma. Ixodes ticks, which are vectors of Borrelia burgdorferi, can also transmit many other microorganisms such as Anaplasma phagocytophilum and Rickettsia helvetica. Nowadays data on the frequency of these co-infections are still conflicting, but in our geographical area (north-eastern of Italy) they appear rather frequently. Aim: To investigate the presence of co-infections with Anaplasma phagocytophilum and Rickettsia helvetica, in patients with proven Borrelia burgdorferi-related cutaneous marginal zone B cell lymphoma. Methods: Four consecutive patients with a histopathological diagnosis of cutaneous marginal zone B cell lymphoma were investigated for the presence of Borrelia burgdorferi with conventional serology and with PCR, and for the presence of Anaplasma phagocytophilum and Rickettsia helvetica with conventional serology. Results: Serologic test for Borrelia burgdorferi was positive in 2 cases, while PCR assays for Borrelia burgdorferi performed on DNA from the biopsy and peripheral blood was positive in all four patients. Serologic analysis for Rickettsia helvetica was positive in one patient, while serologic analysis for Anaplasma phagocytophilum was positive in all patients. Conclusions: Our case series have revealed a co-infection between Borrelia burgdorferi and Anaplasma phagocytophilum in all patients with cutaneous marginal zone B cell lymphoma. Therefore more comprehensive analyses on the co-existence of Anaplasma phagocytophilum infection should be performed in patients with Borrelia burgdorferi-related cutaneous marginal zone B cell lymphoma.

The basal cell carcinoma (BCC) assessment in dermoscopy is based on the recognition of specific characteristics synthesized and described as classical and non-classical criteria, but which may not necessarily present all at the same time. Consequently, a deep knowledge in detecting the aforementioned dermoscopic criteria is crucial in diagnosis. The aim of the study was to evaluate which criteria are more frequently recognized among a group of low-experienced dermoscopists when confronted with the difficult diagnosis of BCC with a diameter lower than 5 mm. We examined 100 BCC finding that data displays a full agreement only for one classical criterion, the lack of pigmented network (Fleiss' κ = 1), while among other classical criteria only arborizing vessels and ulceration exhibit a good agreement among observers (Fleiss' κ > 0.40). Analyzing non-classical criteria, only blue-whitish veil and blue in-focus dots show a good agreement among low-experience observers (Fleiss' κ > 0.40). It is evident that in small size BCC classic dermoscopic criteria are often substituted by non-classical criteria, which represent the neoplasm's early phase. Thus, it is of importance, especially for low-experience dermoscopists, to analyze even the non-classical criteria in order to obtain a diagnosis of early BCC. © 2016 Japanese Dermatological Association

Chronic spontaneous urticaria (CSU) is perceived as a difficult to manage disease with negative impact on quality of life. The aim of this study was to highlight how to improve the care of people with CSU, using the methodology of narrative medicine. From June 2014 to March 2015, CSU-diagnosed patients and their physicians were asked to record their experiences of the condition in writing. Fourteen healthcare teams participated: 41% considered CSU as a challenge to overcome, while 22% experienced CSU as a big commitment. The number of professional involved was evaluated as insufficient in 11 hospitals. Seventy-five percent of the 190 Italian patients had visited 3 or more physicians before receiving a final diagnosis, with a perceived waste of time and resources. The therapeutic pathways were described as unsatisfactory in 83% of cases. As a result, anger and frustration were life-dominant emotions in 92% of patients. The critical points of the care pathway are related to organizational issues and lack of awareness.

Dermoscopy, in expert hands, increases accuracy, sensitivity and specificity in diagnosis of pigmented skin lesions of a single operator, compared with clinical examination. Simplified algorithmic methods have been developed to help less expert dermoscopists in diagnosis of melanocytic lesions. This study included 125 melanocytic skin lesions divided into melanocytic nevi, dysplastic nevi and thin melanomas (

We describe the case of an elderly woman who acquired a Mycobacterium marinum infection following skin exposure to the bacteria through a small wound on her right ring finger, obtained while preparing fish. The resultant sporotrichoid nodules of the right hand and the distal forearm, refractory to the initial therapy with doxycycline and rifampicin, were successfully treated with oral regimen of clarithromycin.

In the present study, we describe the use of electrochemotherapy as alternative therapy for primary cutaneous marginal zone B-cell lymphomas in patients unsuitable for surgery or radiotherapy. Our experience refers to three patients with primary cutaneous marginal zone B-cell lymphomas related to Borrelia burgdorferi infection, treated with specific antimicrobial therapy and electrochemotherapy.

Malignant melanoma presenting as a giant cutaneous mass is rarely observed in clinical practice. A few patients with giant melanoma have been reported, Herein, we document our experience with a patient with giant cutaneous melanoma of the abdomen and review the features of previously reported individuals.

Secukinumab, a fully human monoclonal antibody, neutralizes interleukin-17A, a cornerstone cytokine driving the multiple manifestations of psoriasis. This post-hoc analysis of the SUPREME study was performed to determine the sustainability of response to secukinumab in terms of Psoriasis Area and Severity Index (PASI) 90 in patients with moderate-to-severe plaque psoriasis. Based on PASI 90 response at week 16, patients were stratified as PASI 90 responders (PASI90R, n = 337) or non-responders (PASI90NR, n = 72). At week 20, 94.2% (n = 295/313) achieved PASI 90/100 response in PASI90R, with response maintained through week 48 (89.6%, n = 189/211). An increased proportion of patients achieved PASI 90/100 response in PASI90NR (week 20: 29.9%, n = 20/67; week 48: 57.1%, n = 20/35). Overall, 64.4% patients achieved absolute PASI score = 0 at week 24 with response sustained to week 48 (66.9%). Secukinumab showed sustained and stable efficacy in maintaining PASI 90 response in patients with moderate-to-severe plaque psoriasis up to week 48.
