3.P.20 MALIGNANT GIANT CELL TUMOR OF THE TENDON SHEATH OF THE ANKLE: A CASE REPORT



Abstract

Giant cell tumor of the tendon sheath (nodular synovitis) is a benign soft tissue tumor, usually affecting older women, that most often occurs in the interphalangeal joints of the fingers, wrist or knee. Malign giant cell tumor of the tendon sheath is rare.

We present a case of a 56-year-old woman presented with a slow-growing, painless mass on the anteromedial aspect of the ankle 5 year duration. Apparent rapid enlargement of the mass was observed and went under surgery. The resected tumor, measuring 50x21x28 mm.cm, was encapsulated and located on the tibialis anterior tendon sheath of the ankle.

The tumor was intracapsular and its margins was clear. We performed radioterapy. The patient was quite well at the last follow-up 12 months after wide excision. It seems likely that may expect the good outcome, superficial location and the minority of the tumor composed of malignant component. However, long-term follow-up is mandatory, due to the poor prognosis.
