There are a number of medications which can serve as catalysts for drug-induced immune thrombocytopenia (DIPT). A minimum of six different mechanisms have been put forward as the means by which drug-induced antibodies can encourage platelet destruction, thus emphasising the complexity of the pathogenesis of DITP. Acyclovir, has been widely used because of its highly potent prohibitive properties for infections caused by HSV and VZV. The common adverse effects of this drug are well known, the severe adverse reactions are mostly related to high dose intravenous administrations. The immune thrombocytopenia induced by acyclovir is unusual. The authors present a rare clinical case of acyclovir-induced immune thrombocytopenia in a 72-year-old female patient with typical herpes zoster treated with acyclovir. The clinical and laboratory findings, taken together with the transitory relationship between acycolvir and the start of thrombocytopenia, combined with the elimination of the other know sources of thrombocytopenia, allowed us to reach the diagnosis of acyclovir-induced immune thrombocytopenia. An international database search was employed to complete an extensive review of the current literature. Contemporary information on acyclovir-induced immune thrombocytopenia was collected by the analysis of present day review articles and accessible case reports. The authors found five published cases of acyclovir-induced immune thrombocytopenia. Analyzing these articles it was concluded that immune thrombocytopenia induced by acyclovir is rare, and an unusual side effect, with good prognosis. Prompt diagnosis is vital to appropriate management, therefore clinicians need to be cognisant of this rare potential adverse reaction. [ABSTRACT FROM AUTHOR]

Introduction: Eosinophilic pustular folliculitis (EPF) is a benign, chronic, recurrent condition most commonly described in people of Asian descent. It is found in three clinical forms: classic, associated with immunosuppression especially with HIV infection and infantile form. Clinical case: A 38-year-old patient is consulted for papules and pustules, with a tendency to group and form plaques with central healing and peripheral extension, slightly pruriginous located on the face. The histopathological examination revealed multiple follicular lesions, infundibular spongiosis, eosinophilic follicular pustules in the infundibular segmented, dermal and perivascular perifollicular infiltrate rich in eosinophils. Eosinophilia. HIV negative reaction. Treatment was prescribed with Indomethacin 2x25 mg/day for 40 days with wound healing. Discussions: The etiopathogenesis of EPF is unknown and may be associated with HIV infection, other infections, drugs, other conditions (eg. lymphomas, leukemia), bone marrow or organ transplantation. Clinically is characterized by sterile localized papules and pustules, which meet on the face and trunk, and currently, there are subcornous pustules with eosinophils. Treatment includes several options such as topical with dermatocorticoids and oral indomethacin. [ABSTRACT FROM AUTHOR]

Pityriasis rubra pilaris (PRP) is a chronic papulosquamous disorder of unknown etiology, characterized by reddish orange scaly plaques, islands of sparing, palmoplantar keratoderma, and keratotic follicular papules. The disease can be acquired or inherited, being divided into 5 categories: classic adult type, atypical adult type, classic juvenile type, circumscribed juvenile type, and atypical juvenile type. More recently, an HIV-associated type has been added to this classification. The cases of PRP associated with malignancy are unusual. We present a case of a 58-year-old man, with the typical clinical aspect of PRP with a four-month onset of the disease. The histopathological and dermatoscopical findings confirmed the PRP diagnosis. The routine laboratory results were in normal limits, except the number of eosinophils, which was elevated and the number of lymphocytes, which was lower. After a thorough examination within a hematological consultation, the cause of hypereosinophilia remained unknown. An imagistic examination was performed and a prostate hypertrophy was noted. The prostate-specific antigen (PSA) level was found to be increased. The urologic consultation based on clinical, imagistic and microscopic features diagnosed an early stage prostate carcinoma. The conclusion was a paraneoplastic PRP in association with prostate carcinoma. The search in international databases revealed twelve published cases regarding the association of PRP with malignancies. The presented case represents a rare coexistence of PRP with malignancy, particularly with prostate carcinoma, and indicates that PRP can occur as paraneoplastic dermatosis, heralding a malignancy. This case is the first one to present PRP associated with prostate carcinoma. Nonetheless, in the authors' opinion, PRP can be considered a paraneoplastic syndrome; therefore, tumor screening is mandatory in cases presenting this disease. [ABSTRACT FROM AUTHOR]

Erlotinib is a targeted anticancer therapy used for treating epidermal growth factor receptor (EGFR) mutation positive lung cancer in advanced stage as well as for other malignancies. The most common cutaneous side effect of erlotinib, are well documented; however the number of reports regarding cutaneous leukocytoclastic vasculitis (CLCV) are limited. We report a case, a 58-year-old, 60 kg weight, non-smoking woman suffering of lung adenocarcinoma and brain metastases treated with erlotinib monotherapy with 150 mg/day dose, who presents cutaneous leukocytoclastic vasculitis after 8 months of initiating the treatment. The administration of the drug was discontinued and oral prednisolone treatment was introduced at 1 mg/kg body weight dose for two weeks, decreasing the dose with 5 mg, at every 3 days. The treatment was combined with topical potent steroid and antibiotic therapy used once, daily. The lesions cleared within 7 weeks without recurrence. The treatment with erlotinib was restarted after 14 days with a lower dose of 100 mg/day. The skin lesions have not occurred anymore. Unfortunately the evolution was unfavorable, our patient died 3 months after the vasculitis healing, due to the complications of new metastases that occurred. This may indicate the inefficiency of erlotinib. The late onset of 240 days of the vasculitis and the presumed inefficiency of the drug lead to the speculation that the appearance of cutaneous vasculitis could be a worsening clinical marker of the tumor response. This limited number of cases precludes any meaningful interpretation of data about the erlotinib induced cutaneous vasculitis. Further investigations are needed to assess cutaneous vasculitis.

Lichen sclerosus is a chronic disease of unknown etiology that can occur in the genital area of both sexes. Balanitis xerotica obliterans (BXO) occurs only in the genital area of men and typically affects the foreskin, penile glans, and/or the meatus. In the present report, an observational, descriptive, and retrospective epidemiological clinical study of available data between January 2006 and December 2020 in patients diagnosed with BXO from the casuistic of CMI DERMAMED (Târgu Mureș, Romania) was performed. During this 15-year period, 164 patients were diagnosed with BXO, of whom 70 (42.8%) were in the 51-60-year-old age group. They presented at the medical consultation at 3-9 months after onset of symptoms, where 124 (75.6%) the patients were found to be with stage III of the disease. The most important comorbidities were found to be diabetes mellitus and obsesity, who were treated with potent steroids (betamethasone and clobetasol) with favorable results, with only nine (5.48%) cases necessitating surgical treatment. In general, BXO is a rare, acquired, non-infectious and chronically inflammatory (autoimmune) skin disease that has an unknown etiology. Although the risk of developing this condition is particularly high in patients in the 40-60-year-old age group, it can occur at any age. In the present report, the majority of the patients presented after a long period of disease development, such that they were already in advanced stages of the condition with clinically subjective symptoms and severe sexual problems. This delay in diagnosis has several causes, including misdiagnosis, psychological issues, and sexual behavior. Diabetes mellitus and overweight/obesity tended to be important comorbidities of BXO since the majority of the patients were also affected by these conditions. These comorbidities can exert an important pathophysiological influence on BXO. The first-line treatment option for this condition is the local application of potent steroids, with favorable effects. Due to the risk of malignant transformation as a result of BXO, it is recommended that these patients should be followed up for a longer period. [ABSTRACT FROM AUTHOR]

Transient acantholytic dermatosis (TAD) is a benign, non-familial, non-immune mediated acantholytic disorder of unknown etiology. The presence of polymorphous, unorganized, pruritic lesions on the trunk, associated with focal acantholysis and dyskeratosis, resembles a wide variety of dermatoses. The etiology of TAD (also known as Grover's disease) is unknown, and the success of treatment relies on the correct identification of the disease; however, some cases are refractory to all forms of therapy. For accurate diagnosis, a comprehensive literature review is required. Here, the case of a 55-year-old male with TAD displaying a Darier-like histopathological pattern was reported. The patient was successfully treated with retinoids and acitretin (Neotigason), as well as dapsone, an anti-inflammatory agent, as maintenance therapy. The presence of more than two histological findings, limited to small foci and clinical information, can diagnose Darier disease. The exact pathogenesis has not been elucidated, thus further studies of the pathogenesis of TAD are required. [ABSTRACT FROM AUTHOR]

Keratosis pilaris atrophicans faciei (KPAF) is a hereditary follicular disorder, an atrophicans subtype of keratosis pilaris (KP) with a highly elusive diagnosis. Clinically, it presents with follicular, horny papules surrounded by an erythematous halo of the cheeks, forehead, chin and eyebrows, and it is followed by a gradual hair loss on the lateral margins of the eyebrows. The onset is as early as a few months after birth, but it is mainly diagnosed in children and adolescents and it can persist through adulthood. At present, the natural progression of the disease is poorly understood, which makes a correct diagnosis highly unlikely. The aim of the present study was to describe the clinical characteristics of KPAF in patients encountered in daily practice, in order to find common characteristics that may aid in the earlier recognition of the disease. An observational, descriptive, retrospective study was performed on 14 patients diagnosed with KPAF between January 2000 and December 2020. The mean age at diagnosis was 17.04 years and the onset of clinical symptoms appeared at a mean age of 4.85 years. The first clinical symptom was KP involving either the upper or lower limbs, or both. Then, erythema of the face appeared at a mean age of 7.21 years, keratotic papules on the face at a mean age of 8.35 years and, finally, loss of hair on the lateral margins of the eyebrows at a mean age of 14 years. The patients also had concomitant xerosis cutis, multiple mole syndrome, acne, contact dermatitis and Laugier-Hunziker syndrome. Evidence of disease progression, associations, as well as efficacious treatment measures are lacking. An earlier diagnosis potentially allows for a more efficacious, targeted treatment option. Either topical emollients, systemic retinoids or laser therapy may prove effective for each patient individually. [ABSTRACT FROM AUTHOR]

Dual-energy X-ray Absorptiometry (DEXA) determines the mineral contents for the spine, the proximal femur and the entire body. A group of 36 patients with psoriatic arthritis were chosen, with different types of arthropathy, from the total 82 patients with psoriatic arthritis in the study group, for which bone mineral density (BMD) was measured, using the DEXA technique. The chosen study group comprised 12 men, 12 premenopausal women and 12 menopausal women, with psoriatic joint damage and a group of 36 healthy individuals, divided based on the same criteria: Men, premenopausal and menopausal women. This study did not emphasize an association between the patient type and the presented bone demineralization type (χ2(2)=4.473, P=0.107) in men. In premenopausal women, there was a significant association between the patient type and the presented bone demineralization type (χ2(2)=8.778, P=0.012), as the female patients with psoriatic arthritis presented total and partial demineralization to a larger degree, compared with healthy individuals. In menopausal women, this study did not highlight an association between the patient type and the presented bone demineralization type (χ2(2)=4.523, P=0.104). Bone demineralization was significant in all three patient groups, both total and partial, in patients with psoriatic arthritis compared with healthy patients. Bone demineralization manifested as osteopenia, with T-scores ranging from -2.5 to -1, and not as osteoporosis. Determining B MD by DEXA technique revealed osteopenia to a higher degree within the group of patients with psoriatic arthritis compared with the healthy patients, as well as the absence of osteoporosis in psoriatic arthritis.

With the advancement of urine test automation and the large-scale application of quality management policies, the source of the most crucial errors has become the pre-analytical phase. This study is an attempt to compare the results obtained from the examination of urine strips with those obtained by microscopic examination of urinary sediment, highlighting discordant results. This observational study was conducted between February and August 2019 in a private medical laboratory in Mureş County, and 2,600 urine samples were analyzed. We calculated the sensitivity, specificity, positive predictive value, negative predictive value for leukocytes, nitrites and red blood cells, taking as reference the microscopic examination of urine summary screening. Urine samples were collected from patients who presented to the laboratory. The 2,600 urine samples were analyzed using strips with 10 parameters: glucose, protein, bilirubin, urobilinogen, pH, specific density, red blood cells, nitrite, and leukocytes, and then using the microscope to examine the urinary sediment. We identified a small percentage (1.92%) of inconsistencies from the 2,600 samples of urine, between urinalysis and the microscopic examination and we identified the causes. The most common discordant results were: false-negatives for nitrite (72%), followed by false-positives results for red blood cells (22%), false-negative results for leukocytes (16%), false-negative results for red blood cells (4%) and false-positives for leukocytes (4%). The study confirmed that discrepancies appear despite the proper instruction of patients., Competing Interests: The authors report no competing interests., (Copyright © 2021, Spandidos Publications.)

Skin endometriosis is a rare disease with variable clinical and histopathological characteristics that depend on hormonal stimuli. The skin is not a common location, as most cases of endometriosis involve pelvic sites, such as the ovaries, peritoneum and bowel. However, the most common extrapelvic site affected is the abdominal wall and this location of the disease is frequently associated with obstetric and gynecologic surgery. Here we report a case of skin endometriosis emerged as a painful subcutaneous nodule located near to the left side of an obstetrical surgery procedure scar. The patient affected was a woman in her reproductive age, with a history of right ovary endometriotic cyst laparoscopically removed and histologically confirmed as a primary endometriosis. Dermatologists should be aware of this condition in any woman with a painful lump located in the proximity of a pelvic surgery-induced scar. Its non-specific clinical appearance may confuse the clinician and may delay the diagnosis and management., Competing Interests: The authors declare that they have no competing interests., (Copyright © 2021, Spandidos Publications.)
