Fibroma of Tendon Sheath Presenting Limited Flexion of the Fingers

Abstract

A 35-year-old Japanese man presented with a 1-month history of limited flexion and radiating pain in the left middle and ring fingers. A physical examination revealed a hard nodular mass in his left palm. Magnetic resonance imaging showed a 2 × 1.5 × 1 cm mass of low intensity on T1-weighted images and high intensity on T2-weighted images and gadolinium enhancement. The tumor was marginally resected, adhering to the flexor digitorum profundus of both the third and fourth fingers. The histological diagnosis was fibroma of tendon sheath. After the surgery, the range of motion and hand function were improved. No recurrence has been observed. Fibroma of tendon sheath usually arises on the fingers and hands with strong attachment to the tendon or tendon sheath. The tumor in the present case probably limited the range of flexion of the fingers by obstruction of the transverse carpal ligament.

A Case of 14-Year-Old Male with Fibroma of Tendon Sheath of the Hand with Novel Chromosomal Translocation 4;10

“…Uncommonly, antecedent trauma is reported [10]. The differential diagnosis should include giant cell tumor, mucinous cyst, lipoma, synovial sarcoma, epidermal cyst, and leiomyoma [3]. Clinically, FTS most commonly behave like giant cell tumors of tendon sheath in that they are firm masses with an intimate anatomic relationship to the tendon sheath.…”

“…Clinically, FTS most commonly behave like giant cell tumors of tendon sheath in that they are firm masses with an intimate anatomic relationship to the tendon sheath. They additionally exhibit similar signal patterns on MR imaging with low to intermediate signal intensity on T1-weighted sequences and intermediate to high signal intensity on T2-weighted images [3, 6, 11, 12].…”

“…The literature on FTS is sparse and largely limited to case reports or small series [3–7]. Commonly, patients present with a painless, minimally tender solitary mass.…”

Fibroma of Flexor Tendon Sheath of Finger: A Rare Tumor of Hand-Revisited

“…The tumors known to cause "trigger wrist" are FTS and tenosynovial giant cell tumor, both tend to adhere to the tendon [11]. However, there have been few reports of the tumor causing complete and flexion limitation of the finger and even limited flexion of multiple fingers [12].…”

“…Commonly, patient presents with a painless, minimally tender solitary mass. However, cases associated with triggering or compression neuropathies have been described when underlying tendons or nerves are affected [3][4][5][6][7][8].…”
