A Case of Pigmented Apocrine Hidrocystoma Occuring on the Vulva

Abstract

A 7-year-old female was presentd with two black papules and linear pigmentation between papules on the vulva. No other abnormalities were found in her personal and family history. Histopathological examination was consistent with the apocrine hidrocystoma and the pigment in the luminal cells was iron negative and Fontana Masson positive, confirming its melanin nature. We herein report a 7-year-old female patient with pigmented apocrine hidrocystoma occuring on the vulva with the evidence of melanin as the underlying mechanism of the pigmentation.
