Recurrent Giant Cell Tumor of Tendon Sheath: A Case Report

Giant cell tumor of tendon sheath (GCTTS) is a benign tumor, yet its recurrence appears to be a concern of many surgeons. GCTTS is commonly seen in the hand, and it presents as a slow-growing, painless mass. The best treatment of GCTTS and its recurrence remains controversial. However, it is recommended to perform tissue diagnosis via fine needle aspiration cytology (FNAC) for preoperative planning, then a complete excision under magnification to reduce the recurrence rate of GCTTS. This article illustrates the management of a case of recurrent GCTTS of the flexor digitorum profundus of the right hand by complete excision.
