A Case of Dermatofibrosarcoma Protuberans in the Skin over the Breast.

Dermatofibrosarcoma protuberans (DFSP) is a slow-growing but locally aggressive, fibrous tumor that has a high rate of local recurrence after surgical resection. This tumor occurs most commonly in the trunk and proximal extremities. In this report we present a case of dermatofibrosarcoma protuberans in the skin over the breast which was re-excised after pathological diagnosis, considering cosmetic aspects. Only three other cases of dermatofibrosarcoma protuberans of the anterior chest wall have been encountered in our hospital, and all of these cases were male. The presence of this tumor in the skin over the breast appears to be rare in females. Careful complete resection is recommended for this type of tumor.
