Two Cases of Coccygeal Polypoid Eccrine Nevi Presenting as Skin Tags

Abstract

An eccrine nevus is a rare hamartoma characterized by an increase in the number or size of eccrine glands. Eccrine nevi usually present as localized hyperhidrosis and are not associated with overlying skin abnormalities. However, among the cases that have been reported in the literature, some unique presentations of eccrine nevi have been demonstrated, including a pigmented patch, a depressed nodule, linear papules, and a sacral skin tag. Herein, we report two unusual cases of coccygeal polypoid eccrine nevi and review the literature. (Ann Dermatol 21(4) 440∼442, 2009)

Coccygeal polypoid eccrine nevus associated with imperforate anus and unilateral multicystic kidney dysplasia

“…The unusual location of the coccygeal eccrine nevus (CPEN) has been reported in four cases (Table ) . Our review of the English‐language literature emphasizes the interest of separating this entity from other eccrine nevi.…”
