Multiple poromas in a bone marrow transplant recipient: A case report.

A poroma is a benign epithelial neoplasm that most commonly presents as a solitary papule on the palm or sole. We report the case of a 25-year-old male, with a history of acute myelogenous leukemia, who developed multiple poromas on the feet. Poromatosis - the occurrence of multiple poromas - has been described in six adults and one child; it appears to be more prevalent in patients with a history of lymphoproliferative disorder or radiation exposure.
