Abstract

Aneurysmal benign fibrous histiocytoma, which is a rare variant of benign fibrous histiocytoma, usually occurs as a solitary nodule on the limbs of young to middle aged adults. The clinical diagnosis of fibrous histiocytoma is seldom considered in the differential disgnosis, which may include malignant melanoma, hemangioma, neurorfibroma, and nonspecific cyst. Histopathologically, aneurysmal benign fibrous histiocytoma is characterized by the presence of large blood-filled tissue space which is surrounded by histiocyte, fibroblast, hemosiderin pigment, and capillaries. We report a case of aneurysmal benign fibrous histiocytoma in a 15-year-old boy, who had a solitary nodular lesion on the left knee for a 2 year duration.
