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.

Figure

  • Figure 1 The initial plane X-ray shows no specific sign of bone.

  • Figure 2 (A) MRI of her right knee. The ovoid mass like lesion in the infrapatellar fat pad area, shows isointense on sagittal SE T1-weighted image. (B) MRI SE T2-weighted image of her right knee. This mass is relatively well defined margin and homogenous signal intensity.

  • Figure 3 Arthroscopic picture of the mass presents as a single mass measuring 36×30×20 mm in diameter. It has well defined capsule, and varies in color from reddish brown to dark brown.

  • Figure 4 (A) Microsopic finding of a benign fibrous histiocytoma. Characteristically most are composed of apindle cells arranged in fasicular form and round histiocyte like cells (H & E, ×200). (B) Microsopic finding of a benign fibrous histiocytoma stained by vitmentin (×400) presented positive.
