Metastatic cellular fibrous histiocytoma

Fibrous histiocytoma is a common benign cutaneous tumor. Although most cases of fibrous histiocytoma pursue an indolent course, rare cases have been reported that show aggressive courses with metastases and fatality despite a benign pathology. Here, we present a 30-year-old man with metastatic cellular fibrous histiocytoma. To our knowledge, this is the first case report of such a disease entity in Taiwan.
