Giant-cell fibroblastoma with pigmented dermatofibrosarcoma protuberans component. 1994

Department of Pathology, General Hospital, Trencín, Slovakía.

A unique case of giant-cell fibroblastoma that contained a pigmented dermatofibrosarcoma component (Bednár tumor) is described. The melanin pigmented dendritic cells found in the dermatofibrosarcoma component were round or spindle-shaped and had bipolar extensions. They were S-100 protein positive. Our case indicates the close histogenetic relationship between giant-cell fibroblastoma and dermatofibrosarcoma protuberans. The occurrence of the pigmented melanin-laden dendritic cells in our tumor further substantiates the theory that Bednár tumor is a pigmented variant of dermatofibrosarcoma protuberans.

D018223	Dermatofibrosarcoma	A sarcoma of the deep layers of the skin. The tumors are locally aggressive tends to recur but rarely metastatic. It can be classified into variants depending on the cell type tumors are derived from or by its characteristics: Pigmented variant from MELANIN-containing DERMAL DENDRITIC CELLS; Myxoid variant, myxoid STROMAL CELLS; Giant cell variant characterized by GIANT CELLS in the tumors; and Fibrosarcomatous variant chracterized by tumor areas histologically indistinguishable from FIBROSARCOMA.
