Giant cell tumor of the tendon sheath occurs most often in the hand. Pedal involvement is usually at the dorsal and lateral aspects of the foot. We present an unusual medial localization of giant cell tumor of the tendon sheath in the foot, causing tarsal tunnel syndrome. ? 2011.[SDGs]SDG3adult; article; cancer surgery; case report; electromyography; foot pain; foot radiography; giant cell; giant cell tumor; human; human cell; laboratory test; male; medical history; mononuclear cell; nerve conduction; nuclear magnetic resonance imaging; paresthesia; physical examination; priority journal; tarsal tunnel syndrome; tendon sheath; tumor localization; tumor volumejournal article10.1016/j.fjmd.2011.03.0082-s2.0-79956048638
