Eccrine Porocarcinoma (EPC) is a very rare malignant sweat gland tumor, first described by Pinkus and Mehregan in 1963 as Epidermotropic eccrine carcinoma. The term “eccrine porocarcinoma” was later coined by Mishisma and Morikoin 1969. It is considered as the malignant counterpart of eccrine poroma, a benign tumor of the intraderamal sweat gland. Porocarcinoma is commonly found in elderly, usually in the lower extremities. The scalp is a rare site of affliction. The tumor may present as nodular, infiltrative, ulcerated or polypoid growth. Surgical resection is the treatment of choice. We report a case of EPC of scalp arising from a pigmented eccrine poroma in a 66-year-old male treated with surgery.
