Eccrine Poroma of the Auricle: A Case Report

ABSTRACT

Eccrine poroma is described as a benign neoplasm originating from the intraepidermal eccrine duct of sweat glands. This tumor is known to arise in bare skin areas, but more rarely appeared in head and neck region. A 54-year-old female presented with a mass on the retroauricular aspect of the left auricle. There was a soft, protruding, and purple-colored, solitary mass of about 1.0x1.0 cm in size. After authors performed an excisional biopsy, eccrine poroma was confirmed histopathologically. Thus, we report a rare case of eccrine poroma of the ear with the review of literature.
