Abstract

BackgroundGiant cell tumor of the tendon sheath (GCTTS) is a benign soft tissue (synovial membrane) tumor that rarely involves the hands or wrists. And Tendon impairment caused by GCTTS is extremely rare.Case presentationHere, we reported a case of a 60-year-old female with a 10-year history of gradually increasing mass in her left dorsal wrist. The EIP tendon was partially impaired by the mass.The patient was treated with surgical excision of the mass and reconstruction of the EIP tendon. The histopathological examination suggested the presence of GCTTS. After surgery, the patient had adequate functional recovery and no tumor recurrence after 2 years’ follow-up.ConclusionGCTTS in hands and wrists rarely damages the tendon. Early diagnosis and proactive interventions may likely contribute to good prognostic outcomes.

Highlights

Giant cell tumor of the tendon sheath (GCTTS) is a benign soft tissue tumor that rarely involves the hands or wrists
Giant cell tumor of the tendon sheath (GCTTS), which originally arises from the synovial cells of tendon sheaths or tendinous spaces, is a slow progressing benign tumor [1,2,3]
GCTTS is composed of synovial mononuclear cells and osteoclast-like multinucleated giant cells [12]

Summary

Introduction

Giant cell tumor of the tendon sheath (GCTTS) is a benign soft tissue (synovial membrane) tumor that rarely involves the hands or wrists. We present a case report of localized GCTTS in the wrist. MRI scans (Fig. 1) showed a mass in her left dorsal wrist, arising from the extensor indicis proprius tendon, and a partial tear in the left wrist triangular fibrocartilage disc.
