Abstract:
Ulnar tunnel syndrome (UTS) is a compressive neuropathy of the upper extremity that shows various clinical symptoms according to the anatomic region of the compression site. Numerous factors may cause UTS, and most publications are case reports describing various etiologies; thus, obtaining a correct diagnosis is often challenging. Giant cell tumor of the tendon sheath (GCTTS) is well described to be a common benign soft tissue tumor of the hand; however, it is rarely reported to cause UTS. We report a case of GCTTS in Guyon's canal causing UTS that was misdiagnosed as handlebar palsy.
