Giant cell tumor of tendon sheath—Use of fine-needle aspiration cytology for diagnosis

Neha Meena, Pooja Arora


Giant cell tumour of the tendon sheath (GCTTS) is a slow-growing, usually painless benign lesion of soft tissues. We report the case of a 38-year-old male with a painless, slowly enlarging swelling on right thumb in order to highlight the role of fine-needle aspiration cytology (FNAC) in diagnosing GCTTS.
