DERMATOFIBROSARCOMA PROTUBERANS : A CASE REPORT

Abstract

Dermatofibrosarcoma protuberans is a protuberant tumor developing in the skin, which is relatively rare in Japan. The tumor respected here developed on the shoulder and was treated by surgery and irradiation. A 24-year-old female had complained of a tumor on the right shoulder for ten years. She was admitted to our hospital because of rapid growth of the tumor over the previous year. The tumor was 8.4 × 6.8cm in size, elastic and soft in consistency. Its surface showed teleangiectasia. A uniform, low density echo pattern was observed in the internal region by ultrasonography. At surgery the tumor was well fixed to the skin and had abundant blood vessels on its surface, but it was loosely adherent to the fascia. The tumor was excised with the skin and connective tissues. The pathological findings exhibited a typical pattern of dermatofibrosarcoma protuberans. To prevent recurrence, Linac irradiation was done. The patient is well 11 months after the operation.
