Objective: To report a case of late-onset self-healing Langerhans cell histiocytosis. Case description: A 4½-month-old female patient presenting with an eythematopurpuric eruption underwent a skin biopsy for histopathology and was first diagnosed with isolated cutaneous Langerhans cell histiocytosis. Her lesions regressed within a few months and she was retrospectively diagnosed with late-onset self-healing Langerhans cell histiocytosis after being without skin or systemic involvement in a follow-up four years later. Comments: Self-healing Langerhans cell histiocytosis, which is characterized by clonal proliferation of Langerhans cells and presents with cutaneous lesions, is a rare self-limited variant of histiocytosis and can only be diagnosed retrospectively, after the patient remains free from systemic involvement for several years. Although it presents at birth or during the neonatal period, only a few cases of its late-onset type regarding the age of onset have been reported. Purpuric lesions that appear after the neonatal period serve as a clue for late-onset self-healing Langerhans cell histiocytosis and the patients should be monitored regularly for systemic involvement if the diagnosis is confirmed by a cutaneous biopsy.

Orofacial granulomatosis is a rare chronic inflammatory disorder characterized by persistent or recurrent soft tissue swellings, oral ulceration, and other orofacial features in the absence of an identifiable granulomatous disease. We report a case of a 61-year-old woman with recurrent ulcerations and swellings in her oral mucosa. She was diagnosed as orofacial granulomatosis based upon clinicopathological correlation after exclusion of other granulomatous diseases and showed a favorable response to systemic corticosteroid treatment.

Although the exact pathogenic processes involved in vitiligo are still unknown, its association with autoimmune disorders and endocrine dysfunction has been reported. One of its associations is with thyroid diseases. The purpose of this retrospective study was to determine the prevalence of thyroid function tests and thyroid autoantibody abnormalities in children diagnosed with vitiligo and compare the results with the literature. The laboratory documents of thyroid function tests (FT3, FT4, and TSH) and thyroid autoantibodies (TgAb and TPOAb) belonging to the pediatric vitiligo patients were studied retrospectively. Thyroid function tests and thyroid autoantibody abnormalities were detected in 20 (25.3%) of the pediatric vitiligo patients. Thirteen (16.4%) patients were evaluated as subclinical hypothyroidism, two (2.5%) were evaluated as hypothyroidism, and five (6.3%) were evaluated as euthyroidism. Thyroid autoantibodies were found to be positive in nine (11.3%) patients. Previously reported prevalence of thyroid disease in children with vitiligo ranged from 10.7 to 24.1%, and the prevalence of 25.3% determined in this study was compatible with the literature. Also, the high rate of subclinical hypothyroidism determined in these patients attracted attention to the probable development of overt hypothyroidism in a long term. Thus, our results suggest that thyroid function tests and thyroid autoantibodies should be analyzed in children with vitiligo. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was to determine the real spectrum of skin diseases in Turkish children and how they were managed. Methods: Data on a total of 6000 consecutive patients aged 0--18 years attending the pediatric dermatology clinic were analyzed for diagnosis, disease group, diagnostic pattern, treatment modality, and referral and hospitalization frequency. Results: Allergic skin diseases (49.9%) were the leading group of dermatoses, which were followed by infectious diseases (20.5%), and disorders of skin appendages (10.2%). Atopic dermatitis was the most common dermatose, which was followed by papular urticaria and unclassified eczema. Most of the patients (92.0%) had diagnosis on clinical basis, whereas skin biopsy was performed in 3.7% and laboratory investigation in 4.4% of the patients. The hospitalization rate was 0.3%, and Henoch--Schöönlein purpura was the most frequent dermatose for which hospitalization was required. Local treatment was prescribed in 56.0% of the patients, local treatment and systemic treatment together in 26.4%, and systemic treatment in 6.2%. Viral warts followed by viral exanthems caused by enteroviruses and acquired melanocytic nevi were the most frequently referred skin problems. Further investigation and treatment for systemic or related diseases was the most common reason for referrals (2.1%), and pediatrics was the department to which most of the referrals were made (1.8%). Conclusion: This study provided important data on the spectrum of skin diseases encountered in the pediatric age groups and general approach to patients in a pediatric dermatology clinic in Turkey.

Intramuscular haemangioma ore rare benign neoplasms which are usually asymptomatic until a growth spurt occurs in the second or third decade of life. The case of intramuscular haemangioma occurring in the masseter muscle of a 9-yea-old girl is presented here. Magnetic resonance imaging and colour Doppler ultra sonography revealed the vascular nature of the lesion, and fine needle aspiration was strongly suggestive of the diagnosis and excluded other soft tissue tumours. Treatment options were reviewed and a "wait and watch" policy was adopted until her adolescence for excision in case of more invasive growth causing cosmetic problems and severe pain.

Pemphigus is a group of rare and life-threatening autoimmune blistering diseases of the skin and mucous membranes. Although they occur worldwide, their incidence shows wide geographical variation, and prospective data on the epidemiology of pemphigus are very limited. Objective of this work is to evaluate the incidence and epidemiological and clinical features of patients with pemphigus in Turkey. All patients newly diagnosed with pemphigus between June 2013 and June 2014 were prospectively enrolled in 33 dermatology departments in 20 different provinces from all seven regions of Turkey. Disease parameters including demography and clinical findings were recorded. A total of 220 patients were diagnosed with pemphigus during the 1-year period, with an annual incidence of 4.7 per million people in Turkey. Patients were predominantly women, with a male to female ratio of 1:1.41. The mean age at onset was 48.9 years. Pemphigus vulgaris (PV) was the commonest clinical subtype (n=192; 87.3%), followed by pemphigus foliaceus (n=21; 9.6%). The most common clinical subtype of PV was the mucocutaneous type (n=83; 43.2%). The mean Pemphigus Disease Area Index was 28.14±22.21 (mean ± Standard Deviation). The incidence rate of pemphigus in Turkey is similar to the countries of South-East Europe, higher than those reported for the Central and Northern European countries and lower than the countries around the Mediterranean Sea and Iran. Pemphigus is more frequent in middle-aged people and is more common in women. The most frequent subtype was PV, with a 9-fold higher incidence than pemphigus foliaceus.

Introduction: Cryosurgery is an alternative treatment for many benign, premalignant, and malignant lesions of the skin., Aim: To review the indications of cryosurgery for cutaneous lesions., Material and Methods: The retrospective study was based on the assessment of medical records of 1031 dermatology patients who had cryosurgery., Results: One thousand two hundred and forty-four sessions of cryosurgery were applied to the total of 1031 patients. Of the 1031 patients, the most frequent indication for cryosurgery was common warts which were present in 535 (61.59%) patients, followed by anogenital warts in 119 (11.54%) patients, callosity in 81 (7.85%) patients, actinic keratosis in 77 (7.46%) patients, molluscum contagiosum in 35 (3.39%) patients, and other benign or malignant skin lesions., Conclusions: Cryosurgery is still a valuable treatment of choice in various benign, premalignant, and malignant skin diseases but seems to be underused for indications other than viral warts.
