Abstract

We reported two cases of giant cell tumor of the tendon sheath (GCTTS) with intraosseous invasion of the carpal and metacarpal bones.<BR>The first case was a 26-year-old female. She noticed an asymptomatic mass on the dorsal aspect of her left wrist. Radiographs showed bony erosion like a punched-out lesion of the fourth and fifth carpometacarpal joints. MRI showed intraosseous invasion of tumor. Needle biopsy revealed that the tumor was GCTTS. Simple resection and bone curettage were performed. At 1 year and 5 months after the surgery, no recurrence was seen.<BR>The second case was a 60-year-old male. Resection of the tumor at the volar wrist was performed six years ago and its diagnosis was GCTTS. Three years after the previous surgery, he noticed soft mass on the volar and dorsal aspects of the left wrist. The mass increased in size gradually. He was referred to us and radiographs showed bony indentation of the third and fourth carpometacarpal joints. We diagnosed this tumor as a recurrence of GCTTS and performed a second resection. At two years and two months after the second surgery, no recurrence was seen.
