Abstract

An apocrine hydrocystoma is a translucent cystic nodule that looks like adenomatous cystic proliferation of an apocrine gland, which originated from a hair germ. Dermoid cyst is a cystic teratoma that contains developmentally mature skin appendages, such as hair follicles, sweat glands, and other tissues derived from the ectoderm. Many investigators believe that dermoid cysts re originated from the ectoderm, specifically the hair germ cells. A 58-year-old woman was presented with a purple, asymptomatic, dome-shaped nodule on her right lower eyelid that had been slowly increasing in size for several years. Histopathological examination revealed two well-demarcated cysts: one was lined with stratified squamous epithelium with mature hair and sebaceous glands and the other contained large cystic spaces, which papillary projections extended. We report a rare case of a dermoid cyst, combined with an apocrine hydrocystoma, occurring in the right lower eyelid.
