RESUMO

We report two cases of proliferating trichilemmal cyst in a 61-ear-old woman and a 44-year-old woman who had a solitary tumor, on the left temporal area of the scalp and right flank, respectively. Histologically, the tumors were localized in the dermis and corisised of multilobulated cysts. The cyst walls were composed of liquamous epithelium showing trichilemmhl keratinization. Some of the cells had clear cytoplasm and were positive on PAS staining. Individiial cell keratinization, mild nuclear atypia were also found in the cyst walls. For the treatment, surgical excision was performed with sufficiert margin.

RESUMO

BACKGROUND: Many physiologic, pharmacologic and immunologic abnormalities were reported in atopic dermatitis but the cause and pathogenesis of the disease remain obscure. OBJECTIVE: This study was done to investigate the systemic immunologic abnormalities in atopic dermatitis. METHOD: To evaluate the cell mediated immunity, me quantified pei ipheral blood T lymphocytes and their subsets, using flow cytometery, and assessed plasma neopteiin levels by means of radioimmunoassay. To evaluate the abnormal humoral immunity, we assessed the serum IgE levels by means of enzyme-immunoassay. RESULTS: Mean proportions of peripheral blood T lymphocytes and, heir subsets in atopic Dermatitis patients were within normal limits. Hut the suppvessor/cytotoxic T lyrphocytes(T8) were significantly decreased in the group of se"ere atopic dermatitis compared with the group of mild atopic dermatitis(P0.05). Mean serum IgE levels in the patients with atopic dermatitis were higher than reference value. But there was no significant difference between the mild and severe atopic dermatitis group. Serum IgE levels ivere negatiiely correlated with T8(r=-0.3774, P<0.05) and positively with T4/T8 ratio(r =0.5007, P<0.05). Conclusions : These data;uggest that the atopic der matitis has abr ormalities in cell mediated immunity as well as elevated IgE level.
