Abstract
Dermatofibrosarcoma protuberans (DFSP) is a malignant, slowgrowing, locally aggressive tumor of the skin with a high rate of recurrence. It is a very uncommon malignant skin tumor, especially in the head and neck area (10-15% of cases). This case report discusses a rare case of scalp DFSP.

Background: To our knowledge, there is a hypothesis regardingthe association of vitiligo with other autoimmune disorders.Organ-specific autoantibodies are found more frequently in theserum of vitiligo patients. Recent studies have demonstratedthe role of alterations in serum transforming growth factor-beta(TGF-beta) released from regulatory T cells in the pathogenesisof depigmentation observed in vitiligo. It has been shown that incomparison with patients without autoimmune diseases, serumTGF-beta levels increase in patients whose vitiligo is associatedwith autoimmune diseases. We hypothesized a relationshipbetween serum TGF-beta levels and organ-specific autoantibodiesthat could predict other autoimmune diseases in vitiligo patients.Method: Forty-five patients with a mean age of 35.96±13.34years who had stable vitiligo since 1 year ago and involvementof up to 30% body surface area were enrolled. Organ-specificautoantibodies (ANA, anti mitochondrial Ab, anti TPO (antithyroid microsomal Ab), anti parietal cell Ab, anti thyroglobulinAb) and serum TGF-beta level were evaluated.Result: Twenty-three patients (51.11%) had at least one positiveorgan-specific autoantibody. Anti TPO in 16 patients, antithyroglobulin Ab in 9 patients, anti parietal cell Ab and ANAeach in 5 patients, and anti mitochondrial Ab in 4 patients werepositive. Mean serum TGF-beta level was 105.82±30.33; there wasno significant difference in serum TGF-b level between patientswith and without positive organ-specific autoantibody (P=0.26).Conclusion: Although another study showed the relationshipbetween serum TGF-beta levels and autoimmune disordersin vitiligo patients, we did not find a significant difference inserum TGF-beta levels in these patients regarding the positivityof organ-specific antibodies. It may be due to the fact that ourpatients had autoantibodies without clinical autoimmune diseaseexcept vitiligo.

Background: Recent studies suggest that psoriasis may be a pathogenic factor for the metabolic syndrome and atherosclerosis. The aim of our study was to investigate the metabolic state in psoriatic patients in order to clarify the association between psoriasis and insulin resistance.Methods: This single-centre, case- control study was performed between 2008 and 2010 to evaluate the metabolic state of thirty chronic plaque type psoriatic patients in comparison with the control group. The criteria of insulin resistance (Body Mass Index (BMI), Systolic Blood Pressure, Fasting Plasma Glucose, Oral Glucose Tolerance Test (OGTT), Serum Insulin and Lipid Profile) were assessed for each participant.Results: Thirty psoriatic patients with a mean disease duration of 3.94 + 2.96 years and 30 healthy controls were recruited for the study. Only one patient in each group filled the criteria of insulin resistance, and there was no significant difference between the two groups. The mean Fasting Plasma Glucose (FPG), Triglyceride (TG) and Systolic Blood Pressure (SBP) levels were significantly higher in psoriasis patients as compared to the controls (p=0.044, p=0.014 and p=0.001, respectively). In contrast, no statistically significant differences were observed in mean BMI, OGTT, insulin and HDL levels between the two groups.Conclusion: Despite the absence of any significant association between insulin resistance and psoriasis, it could be concluded that psoriasis may be an independent risk factor for diseases such as Ischemic Heart Disease (IHD) and Diabetes Mellitus (DM), hypertension and obesity.
