Giant cell tumor of tendon sheath
Chapter: 26
Benign tumor of giant cells in the vicinity of a joint. This lesion is probably non-neoplastic, and is closely related to pigmented villonodular synovitis. The latter condition is characterized by an exuberant, heavily pigmented villous synovial overgrowth containing pigmented cells, lipid-laden histiocytes, and multinucleated giant cells.
