A Case of Giant Cell Tumor of Tendon Sheath on the Palm / 대한피부과학회지

ABSTRACT

A 36-year-old female presented with a 5-month history of an indurated asymptomatic nodule on the left palm. A skin biopsy was done and the histopathological findings were consistent with those of a giant cell tumor of tendon sheath (GCTTS). A GCTTS occurs in the tendon sheath of digits or in the joints of the extremities, and most commonly involves the distal fingers. However, palmar involvement of this tumor is unusual. We present a case of GCTTS on the palm.
