Eccrine Hidrocystoma of Eyelid Masquerading as Epidermal Inclusion Cyst: A Rare Case Report with Review of Literature.

Abstract

Eccrine hidrocystomas are rare, benign cystic lesions that usually affect the scalp, cheeks, and eyelids. They are thought to originate from the sweat glands. These lesions can be single or many in nature and frequently worsen in the summer from increased perspiration. They are caused by dilated ducts of eccrine sweat glands. Clinically, they seem like small, transparent cystic lesions that are painless, and they usually affect middle-aged or older people. However, a histological study is necessary to make a final diagnosis. We present a case of a 35-year-old woman who had an epidermal inclusion cyst first identified as a single, painless cystic growth on her right lower eyelid.
