Diffuse Tenosynovial Giant Cell Tumor of the Wrist with Joint Destruction and Invasion

Abstract

Abstract A 54-year-old man took antitubercular drugs for 1 year for right wrist pain, swelling, and restriction of movements, with no improvements. Magnetic resonance imaging wrist reported multiple nodules and soft-tissue mass with intraosseous erosions involving carpal bones, distal radius, and ulna. Resection of the mass, excision of the distal ulna, and wrist arthrodesis were done. The histopathology confirmed a diffuse tenosynovial giant cell tumor (TSGCT). No postoperative radiotherapy or systemic therapies were given. The patient remained symptom-free at 2 years of follow-up. Diffuse TSGCT with joint destruction and invasion of the wrist is rare. Therefore, a high index of suspicion is required before considering the most common infective etiologies in the wrist.
