Teno-synovial giantcell tumor (TSGT) is a rare disease of joint and other synovial tissues. These tumors occur in as circumsribed and in a diffuse form.

The etiology of this benign tumor is still unknown.

Surgical treatment with complete resection in cases with circumscribed forms and compelte synovectomy in cases of the dissue form are recommended.

We report a follow-up of 54 patients treated siurgically between 1960 and 1997.

The mean age was 37.3 years (range, 2-80), the ratio male : female 25:29.

43 patients suffered from the diffus and 11 from the circumscribed TSGT.

Anatomically, mostly the knee joint was involved in both.

Circumscribed TSGT had been treatged by local resection, diffus TSGT with synovectomy.

Follow-up examination of these patients exhibited: excellent/good: 31/53 (58.5%); fair in 34% and poor in 4/53 (7.5%). The rate of recurrence was 21%, all in diffuse TSGT.

Adjuvant radiotherapy was given in 5 patients but had no influence on the long-term follow-up.


Surgical treatment of TSGT is sufficient in the circumscribed form.

All recurrences occured in the diffus form. Regarding the role of adjuvant strategies such as radiotherapy or radio-synoviorthesis no reliable data exist.

Our rate of recurrence is nearly 10% lower than that reported in the literature.
