What is steatocystoma?
Steatocystoma is a benign (noncancerous) skin cyst that arises from a sebaceous gland [1,2].
Steatocystoma simplex refers to a presence of a single cyst, which is usually acquired, and steatocystoma multiplex refers to a condition with multiple cysts, which is usually hereditary .
The term steatocystoma arises from “stear” (fat) and “cystis” (cyst).
In steatocystoma multiplex, after puberty, numerous nontender yellowish or flesh-colored cysts appear on various parts of the body, mainly on the chest, abdomen, upper arms, armpits, neck and face [1,2]. The cysts measure from 3 millimeters to 3 or more centimeters in size, are semi-translucent, soft or firm and without openings [1,4,5]. They contain sebum (a normal content of the sebaceous glands), which appears as a yellow liquid .
Steatocystoma rarely appears in children .
Steatocystoma very rarely develops into cancer .
