Ganglion cysts have been recorded in many areas throughout the body. Intratendinous ganglion cysts in the foot are very rare. We present the case of 51-year-old woman with a recurrent right foot ganglion cyst. Surgical excision revealed a ganglion cyst in the tendon sheath of the extensor digitorum longus. It is important to be aware of potential tendon involvement for ganglion cysts, as surgeons must be prepared to perform tendon repairs in addition to mass excisions if the tendon is compromised.
