A Case of Giant Cell Tumor of the Tendon Sheath Developing on the Dorsum of the Foot / 대한피부과학회지

ABSTRACT

We report a case of giant cell tumor of the tendon sheath involving the foot, in a 21-year-old female patient, who presented with an asymptomatic tumor on the dorsum of her right foot. Histopathologically the tumor is surrounded by thin fibrous connective tissue. The characteristic findings of the excised specimen revealed a typical mixture of abundunt round or polygonal histocyte-like cells with varying portions of spindle-shaped fibroblast-like cells and multinucleated giant cells. Variable amounts of hyalinized fibrous stromal tissue were also present. After excision, local recurrence has not been observed for 3 months.
