Pedunculated dermatofibrosarcoma protuberans (DFSP) on the lower abdomen

Abstract

A 56-year-old Japanese female came to our hospital because of a rapidly growing tumor with pedunculated appearance. From the histopathological and immunohistochemical findings, we diagnosed the patient's condition as DFSP. A pedunculated appearance is relatively rare for DFSP. There have been only six reports, all of which have been from Japan. The reason for the appearance of this tumor is unknown. However, we speculated that the location of the tumor or a racial difference may affect its pedunculated appearance. [Skin Cancer (Japan) 2004; 19: 340-343]
