영문 초록

Bednar tum or is a rare variant of dermatofibrosarcoma protuberans that is characterized by slow growth and a unique storiform pattern and in some cases by the presence of melanin pigment. We recently experienced a case of Bednar tum or arising in the left chest wall. A 25-year old man came to the hospital with a chief complaint of 2.5 cm sized palpable mass on the chest wall. Onset time was unknown, b니t size of tum or increased grad니ally. An excisional biopsy was done and disclosed a well circumscribed tumor consisted of spindle cells arranged in a storiform pattern with some scattered melanin pigmented cells. There were some nuclear atypia and a few atypical mitoses. This tumor invaded extensively peritumoral adipose tissue therefore the boundary of the tumor was uncertain. Immunohistochemically， tumor cells have immunoreactivity for CD34 and C-kit, but not for S-100, desmin and HMB-45. These findings suggested that the mass was consistent with the Bednar Ujmor. W e herein report a case of Bednar tum or with review of the literature.
