Eccrine porocarcinoma of the lower extremity: A case report and review of literature

Abstract

Eccrine porocarcinoma is a rare malignancy of the eccrine sweat gland. It is usually found frequently on the lower extremities, and it affects both sexes equally usually in the sixth to seventh decade. In our case, we present a 42-year-old male patient with a recurring exophytic tumor on the right lower extremity without local extension. The initial tumor was biopsied, excised and diagnosed as an eccrine poroma. The tumor then recurred 6 years later, was re-excised, reconstructed with a soleus muscle flap and diagnosed as an eccrine porocarcinoma. © 2011 Chang et al; licensee BioMed Central Ltd.
