Eccrine Nevus Presenting as a Perianal Skin Tag

Abstract

We present the case of a 9-year-old girl with a perianal skin tag. This asymptomatic lesion was removed for cosmetic reasons and demonstrated a polypoid lesion with a slightly acanthotic epidermis. The dermis was filled with mature-appearing eccrine ducts and glands but with no other cutaneous appendages, adipocytes, or abnormal vascularity. We believe this to represent a polypoid eccrine nevus and that its presentation is unique.
