Giant Cell Tumor of the Tendon Sheath (GCTTS) with Multiple Bone Destruction of Different States: A Case Report

Abstract

Giant cell tumour of tendon sheath (GCTTS) is considered benign, but well known for its high recurrence rate. Bone involvement of GCTTS is not uncommon and closely related to local recurrence after surgery. Radiologic findings of bone involvement are pressure erosion, circumscribed cortical destruction and degenerative arthritis. The treatment involves complete resection of tumor including bone lesion. This case presents GCTTS of young male patient with multiple bone destructions of different state, treated by complete excision of the tumor and curettage of bone lesion.
