Recurrent Multifocal Giant Cell Tumor of Tendon Sheath of the 5th Finger Flexor Digitorum Profundis Tendon: A Case Report

Giant cell tumors of the tendon sheath (GCTTS) typically present as discrete, solitary nodules along a tendon near the joints in the fingers and toes. Multifocal GCTTS along a single tendon is a rare entity in which only a handful of cases have been described. In this article, we present a case of GCTTS in which four separate lesions along the flexor digitorum profundus (FDP) were surgically removed and then recurred fifteen weeks later on the fifth finger of the same hand. This report characterizes the presentation of a GCTTS, the surgical removal, and the post-operative course for this patient.
