Abstract
- Eccrine poroma is a benign neoplasm, arising from the eccrine sweat duct. It generally occurs in middle aged individuals and is most commonly found on the sole or the sides of the foot, followed by the hands and fingers. It presents as a solitary, soft or a rather firm consistent, sessile or often slightly pedunculating, tumor. A 47-year-old woman presented with a 2.5x1.5 sized brownish to erythematous pedunculating mass on the left flank. According to histopathologic finding and immunohistochemical staining (epithelial membrane antigen), the final diagnosis was consistent with eccrine poroma. We report here on an interesting case of eccrine poroma presenting as pedunculating mass on the flank, which is an unusual location.
