Abstract

Malignant eccrine poroma is a rare skin appendageal tumor arising from the intraepidermal ductal portion of the eccrine sweat gland. It may develop either spontaneously or from a long-standing eccrine poroma. It usually affects the aged and is located most commonly on lower extremities. We report a case of malignant eccrine poroma occurring on the suprapubic area of a 75-year-old Korean man. He underwent wide excision and flap coverage.
