Primary giant cell tumor of soft tissue in the finger

Abstract

Primary giant cell tumor of soft tissue (GCTST) arising in a finger is a rare event. We report a case of a 54-year-old man with a primary finger giant cell tumor that appeared histologically identical to giant cell tumor of bone. The patient presented with a cystic mass of the finger. The magnetic resonance imaging showed no relation between the nodule and bone, tendons or synovial tissues. The distinction of this entity from other more common primary finger tumors with giant cell morphology is emphasized.
