Giant cell tumor of the tendon sheath (GCT-TS) is predominantly encountered in the hand, ranking as the second most common solid tumor after ganglion cysts. Contrary to its prevalence in the upper extremity, GCT-TS manifestation in the foot is exceptionally rare. This report delineates a unique presentation of GCT-TS in the foot of a 25 y old female, who presented with a painful, progressively enlarging mass in the lateral aspect of her foot. This case underscores the diagnostic challenges and therapeutic considerations in managing such an atypical presentation of GCT-TS.
