A Rare Case of Multifocal Giant Gell Tumor of the Tendon Sheath Involving Both the Hand and the Foot

795 aspect of the IP joint and the proximal phalanx of the right thumb. Both masses were solid, well-defined, and slightly tender. Mass was measured to be 2 cm on right thumb, 1.5 cm on left plantar region, respectively. On plain radiography of the right thumb, the mass showed a well-defined soft-tissue shadow. There were neither periosteal reactions nor articular involvement (Fig. 1). On plain radiography of the lesion on the left plantar region, there were no notable findings. Surgery was performed under general anesthesia with tourniquet control, using magnifying loupe. Bruner’s incision to the volar aspect skin of the thumb was performed at the level of proximal phalanx. A meticulous dissection was performed with caution to achieve a complete resection of the tumor. Thus, the diaphysis of the right proximal phalanx was exposed. The mass had contact to neurovascular structures as well as both extensor pollicis longus (EPL) and flexor pollicis longus (FPL) tendons. The mass was removed along with the capsule. It was unavoidable, however, A Rare Case of Multifocal Giant Gell Tumor of the Tendon Sheath Involving Both the Hand and the Foot
