Fibroblastoma desmoplastic D23.-

Rare, mostly extensive, benign, predominantly subcutaneous, more rarely cutaneously localized, fibroplastic tumor, which occurs mainly in adult male patients.

Back, upper and lower extremities, also head and neck area (oral area, orbit)

Slowly growing, deep-seated, usually large-volume, plate-like or nodular tumour masses, which, depending on their location, disturb local functions.

Cell-poor, easily delimitable tumour of fibroblastically differentiated cells in a collagen-rich stroma. No increased proliferative activity. No cell atypia. Tumor cells express vimentin and alpha smooth muscle actin, but not desmin, CD34 and S-100 protein. A translocalization t(2;11) (q31;q12) could be detected in the tumor cells (Nishio J et al.).
