Malignant Eccrine Poroma of Abdomen Brief case report.: Jin Ja Park, Young Hee Choi, Kyung Chan Choi, Young Euy Park; Korean J Pathol. 1998;32(4):312-314.

Abstract PDF: Eccrine porocarcinoma is a rare tumor of the skin. A case report of an eccrine porocarcinoma metastasizing to epidural space of spinal cord and inguinal area with a nine year follow up is described. The patient had a nodular growth of the abdomen with both inguinal lymphadenopathy three years before its first excision. After a follow up of nine years, he complained a weakness of lower extremities and back pain. Extradural mass of 10th thoracic vertebra and left inguinal mass were found. Subsequently, the masses histologically identical to the skin tumor were found.

Eccrine Poroma: A report of five cases.: Young Shin Kim, Seok Jin Kang, Byoung Kee Kim, Sun Moo Kim; Korean J Pathol. 1991;25(4):357-362.

Abstract PDF: The eccrine poroma was described first by Pinkus et al. in 1956 as a subgroup of benign solid hidradenoma with the histologic structure resembling acrosyringium. The histologic appearance of eccrine poroma greatly resembles that of seborrheic keratosis and basal cell carcinoma. But the clinical lesion is fairly unique and the tumor is most commonly found almost exclusively on the foot, in the skin of the plantar surface. During the past four years, the authors experienced five cases of eccrine poroma which were diagnosed by histopathological examination of the tumor mass. All the cases occurred in the sole and lateral sides of the foot as well. Clinical and pathological features were reviewed and a brief review of the literatures was done.
