Two Cases of Proliferating Trichilemmal Cyst / 대한피부과학회지

ABSTRACT

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.
