Abstract

Benign fibrous hitiocytoma of the infrapatella fat pad is very rare. It has usually do not induced a pain or a symptom because it was located deep tissue. So it was very difficult to be diagnosed. We experienced a case of deep benign fibrous histiocytoma in a 53-year-old woman. It was diagnosed by MRI. Diagnostic arthroscopic procedure was performed and the lesion was completely resected by open excision. We report a rare case of benign fibrous hitiocytoma presenting as an intra-articular tumor in the joint causing pain and limitation of movement.
