Cutaneous "fibroma-like" perivascular epithelioid cell tumor: A case report and review of literature.

abstract：:A 46-year-old man had a cystic mass on the right side of his scalp. Histological examination revealed a cystic dermal nodule composed of relatively circumscribed lobules of proliferating squamous epithelium, with atypical mitoses and dyskeratotic cells of invasive structure, which was diagnosed as proliferating tricho...
