Dermatofibrosarcoma protuberans (DFSP) is a slow-growing dermal spindle cell tumor. Its rare myxoid variant is characterized by extensive myxoid degeneration. We report a case of myxoid DFSP of the lower abdomen in a 35-year-old man. Histopathologically, the tumor consisted of spindle-shaped cells that were strongly positive for CD34 with a typical storiform pattern and myxoid stromal changes. [ABSTRACT FROM AUTHOR]

Objectives: Patch test is the most reliable method to diagnose allergic contact dermatitis and to find out the responsible contact allergen. The aim of this retrospective study was to evaluate the patch test results of patients with contact dermatitis in our region. Materials and methods: One Hundred fifty patients (84 female and 66 male) with contact dermatitis were patch tested with European standard test series. The testing has been standardized by the international Contact Dermatitis Research Group (ICDRG). Results: A majority of the lesions (36%) were localized on the hands. In 31 female (58,4%) and 21 male (4,6%) patients (a total of 72 patients) there were positive allergic reactions to at least one chemical. Nickel sulphate (13,3%), potassium dichromate (11,3%) and cobalt chloride (8,6%) were the most often allergens reacted. Conclusion: Nickel sensitivity is more common. Comparing with healthy controls contact sensitization may be more prevalent in patients with contact dermatitis. [ABSTRACT FROM AUTHOR]

Objectives: Allergic diseases play an important role in the natural course of psoriasis. Atopic sensitization and contact dermatitis are common in patients with psoriasis. Since the symptoms are prolonged in patients who are resistant to therapy and exposure to itchy and external factors are common among these patients, the effects of contact allergens on triggering psoriasis are investigated. Contact allergens have an important role in activation and remission of psoriasis. We aimed to investigate contact sensitization rates in patients with psoriasis in the study. Material and Methods: Contact sensitization was investigated with the application of European standard series in twenty patients with psoriasis, twenty patients with contact dermatitis, and twenty healthy persons. Results: Among the whole study cases, positivity rate of patch test against one allergen at least was 25%. rate of patch test was 25% in patients with psoriasis, 35% in patients with contact dermatitis, and 15% in healthy persons. There were no significant differences between the groups according to sensitization to one or more allergens (p>0.05). There were no significant difference in clinical subgroup of psoriatic patients according to contact sensitization (p>0.05). The allergens in patients with psoriasis on patch test were as the followings: phenyldiamine, potassium dichromat, nickel, and cobalt. Conclusion: We think that the patch test has a major role in the diagnosis and elimination of allergens in patients with the chronic and resistant diseases and palmoplantar and flexural psoriasis.

Objective: Isotretinoin (ISO) is a synthetic retinoid that is a preferred drug for unresponsive to conventional therapy in the treatment of severe cystic acne. In this study, to evaluate retrospectively laboratory values in patients with acne using oral ISO treatment was aimed. Methods: 40 patients were enrolled to the study that admitted to the dermatology clinic and clinically diagnosed as acne vulgaris and oral isotretinoin treatment was started. Patient's pre-treatment and 3rd month of the teatment values of liver function tests (AST, ALT), blood urea nitrogen and creatinine levels, total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL) and triglyceride (TG) levels were obtained by screening of files. Results: Compared to values of patients before and 3rd month of treatment, statistically significant differences was detected for total cholesterol, LDL, HDL, TG and AST values (p<0.001, p<0.001, p= 0.003, p= 0.01, p=0.001 respectively). Conclusion: We think that starting a good diet before treatment would be useful to prevent TG disorder. In addition, we believe it would be useful to do strict laboratory follow in patients with familial hypertriglyceridemia during treatment. We believe that it is more necessary to follow up the blood lipid values rather than liver and kidney function tests. However, we also think that it would be sufficient to follow up once every 2 or 3 months. [ABSTRACT FROM AUTHOR]

Objective: To determine the immunohistochemical and histopathological changes in facial skin after exposure to maneb (manganese ethylene bisdithiocarbamate), a fungicidal dithiocarbamate pesticide., Study Design: In the experimental group maneb was administered by inhalation to 10 male Wistar albino rats for 5 days each week for 3 weeks. As a biological control, the control group (n = 10) received distilled water by spray for the same time period. The experiment was terminated after 3 weeks. Sections of rat facial skin were examined histopathologically., Results: In the experimental group, microscopic examination of facial skin revealed degeneration of the epidermis, detection of mild inflammatory reaction, and vascular dilation in the connective tissue. Hair follicles and degenerative changes were observed in the deeper parts. In the experimental group, dilation of the blood vessels in the dermis and hemorrhage were supported by an increase in CD34 expression. In addition, a reduction in the number of melanocytes (hypopigmentation) was observed in the hair follicles and epidermis, along with a decrease in the expression of CD117., Conclusion: Epidermal degeneration, intradermal cell infiltration, vascular changes, and reduction in the number of melanocytes in the follicle and content of cytokeratin in both the epidermis and hair follicle keratinocytes were detected after maneb application. These findings may have important implications in the association with main signaling pathways, including keratinocyte proliferation and differentiation. Disruption of these pathways may cause some dermatoses.

Background: We aimed to determine the demographic and clinical features of patients with Behcet's disease (BD) in Southeastern Turkey., Methods: In this study, files of 132 patients with BD (76 females and 56 males) who were diagnosed with BD according to the International Study Group criteria at the Department of Dermatology of Dicle University Faculty of Medicine from 2005 to 2009 were evaluated retrospectively. Demographical and clinical characteristics of the cases were recorded., Results: Mean age of the cases was 32.40 ± 9.4 years (range 15 - 59 years) and male/female ratio was 0.73. The mean age at diagnosis was 28.71 ± 9.1 years. Six cases were diagnosed as juvenile BD (4.45%). Oral aphthous lesions (100%) and genital ulcers (94%) were found to be the most common findings of the disease, followed by pathergy positivity (75%), papulopustular lesions (74.2%), erythema nodosum (43.2%), thrombophlebitis (6.8%) and extragenital ulcers (6.1%). Systemic involvement was noted as joint involvement in 79.5%, ocular involvement in 28.8%, vascular involvement in 9.8%, pulmonary involvement in 2.3%, neurologic involvement in 2.3% and genitourinary system involvement in 0.8%. There was no significant difference between mucocutaneous findings and systemic involvement ratios of male and female cases., Conclusion: Demographic and clinical features of BD may vary according to geographical region, gender and ethnicity. We hope that this study will contribute to the epidemiologic data of BD which may exhibit different clinical and demographic features in different parts of the world.

Background: The purpose of this study was to determine the prevalence of childhood dermatoses in Diyarbakir, which is located in the southeastern region of Turkey., Material and Method: This cross-sectional study was carried out in April 2008 among students of eight randomly selected public primary schools in Diyarbakir. Students were examined and questionnaire was applied to determine socioeconomic levels and socio-demographic features., Results: A total of 1932 students were examined by dermatologists. Nine hundred and fifty three (49.32%) girls, mean age was 11.06±2.13 (range 6-17). The overall point prevalence of skin disorders was 59.1%. Among this sample 776 children (40.2%) had only one skin disease whereas 299 (15.5%) had two and 67 (3.5%) had at least three. The point prevalence of skin disorders was 33.1% among students in grade 1 and 78.9% among students in grade 8 (p<0.05). The most common skin disease was eczema (32.8%), followed by pigmentation disorders (17.2%), skin infections (13.4%), scalp disorders (10.1%) and acne vulgaris (9.6%). Infectious skin problems, pigmentation disorders, hair and scalp disorders and acne vulgaris were more common among girls compared to boys (p<0.05). In addition, infectious skin problems were more common among boarders (p<0.05) compared to day students., Conclusion: Skin disorders affected 59.1% of the studied children. Skin disorders were more common among girls and boarders in this study, this group of children should be given specific attention in formulating preventive measures.
