The case report of a 58 years patient is described. She went to the Orthopedics and Traumatology Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba because she began to notice progressive increase of volume in the back of the left hand around 5 years ago, near the metacarpusphalangic articulation of the third finger that made its extension difficult and was unsightly. By means of the scan, a well defined echogenic image that infiltrated the thickness of the tendon was observed, reason why the exeresis of the tumor was carried out. The infiltration of this tendon was confirmed, which was dried up and substituted with self-graft of the accessory tendon that sends the ring finger tendon. The results of the histologic studies reported that it was a giant cell tumor of the sheath with tendinous infiltration. The hand was immobilized during 3 weeks and the functional recovery was completed at 45 days.
