Eccrine Porocarcinoma of the Scalp: A Rare Case Report with Review of Literature

Abstract

Eccrine porocarcinoma (EPC) is a potentially lethal neoplasm of the skin that arises from the intraepidermal portion of the eccrine sweat glands. It was previously known as eccrine adenocarcinoma or malignant eccrine poroma. It commonly occurs between 60 to 80 years of age, usually arising from hands and feet. However, few case reports on involvement of rare sites such as scalp, face and eyelids are present in literature. We herein report an unusual case of porocarcinoma arising on the right parieto occipital region of scalp in a 29-yearold young female patient. To the best of our knowledge, there have been fewer than 20 cases of porocarcinoma arising on scalp with fewer than 10 cases seen in younger age group reported previously in the literature.
