Unveiling the Enigma: Uncommon Hand Giant Cell Tumor within the Tendon Sheath

Abstract

Introduction: Giant cell tumor of tendon sheath (GCTTS), also known as tenosynovial giant cell tumor or pigmented villonodular tenosynovitis, is a rare benign soft-tissue tumor with an unclear cause. It is the second most frequent soft-tissue tumor in the hand after ganglion cyst.

Case report: We described a female patient, age 19, who has had a 3 cm × 2 cm firm swelling on the palmer aspect of the right second metacarpal region for 7 years. The bulge developed spontaneously and moved quite slowly. It is required to do a histological and radiographic evaluation to determine whether or not to pursue additional treatment. Excision surgery was done, and the tumor was entirely removed. According to histopathology, this mass was compatible with GCTTS without being malignant.

Conclusion: It is an uncommon instance of GCTTS at the hand, to sum up. The tumor should be entirely excised due to its high risk of recurrence to lower the likelihood of recurrence and restore hand function.

Keywords: Giant cell tumor of tendon sheath; pigmented villonodular tenosynovitis; soft-tissue tumor; tenosynovial giant cell tumor.
