Giant cell tumor of the tendon sheath: a rare periungual location simulating myxoid cyst

Abstract

ABSTRACT Giant cell tumor of the tendon sheath is a benign soft tissue tumor most frequent between the third and fifth decades of life. It can mimic and make differential diagnoses with several hand tumors. Definitive diagnosis and the treatment of choice are reached with complete resection and histopathological examination. Here we describe a case with clinical presentation similar to that of a myxoid cyst.
