title: An unusual case of porocarcinoma arising on the scalp of a 22-year-old woman.
abstract: Porocarcinoma is a rare malignant neoplasm that arises from the intraepidermal ductal portion of the eccrine sweat glands. This neoplasm most often presents in elderly individuals on the lower extremities. We present an unusual case of porocarcinoma arising on the scalp of a young patient. To the best of our knowledge, there have been fewer than 20 cases of porocarcinomas arising at this site reported in the literature.
