Fibroma of tendon sheath

Three cases of fibromas involving tendon sheath of right index finger, left ring finger, and tibial ligament in a 62-, a 54-, and a 30-year-old male patients, respectively, are described. Two cases (1 and 2) represented painless, slowly enlarging masses that limited motion of the involved digits. The third case was discovered at surgery during the repair of a tibial ligament after a motorcycle accident. Following surgical excisions, no recurrences were present 18 months and 9 months after resection. The fibromas of tendon sheath origin are distinct entities and should be separated from other lesions of tendon sheaths. Trauma should be considered as the etiology. The fibromas are benign lesions but may recur.
