Abstract
- Benign fibrous histiocytomas are relatively common nodules that are histologically characterized by a proliferation of fibroblastic and histiocytic cells in the dermis. Rarely, some show such cellular atypia that there are some difficulties in differentiating the lesion from sarcoma. Herein we report a 42-year-old man with asymptomatic, solitary, 11 cm sized, red-to-brown colored, broad-based, and firm nodule on the right forearm for about 2 years. Histologically, the lesion was composed of histiocytes, fibroblasts and pleomorphic, bizarre multinucleated giant cells. Despite the cellular atypia, mitotic figures were not found.
