Abstract

Tenosynovial giant cell tumors (TGCTs) are typically benign neoplasms of the joint, bursa, and tendon sheath. Usually, TGCT presents as a small localized tumor on the hand and wrist. The diffuse-type TGCT is more aggressive and mainly affects large joints such as knees, hips, ankles, and elbows. Diffuse-type TGCT of small joints is rare. To our knowledge, this is a very rare case of a huge diffuse-type TGCT on the wrist. We report a huge TGCT, which grew gradually over 10 years.

  Fig. 1. (A) A magnetic resonance imaging scan showed an extensive multi-lobulated soft tissue mass in the volar aspect of the patient's wrist, arising from the flexor tendons. (B) A magnetic resonance imaging scan showed an extensive multi-lobulated soft tissue mass in the volar aspect of his hand, arising from the flexor tendons.

  Fig. 2. (A) Mass located only on the surface of the flexor tendons. It had partially infiltrated the tendons. (B) The mass consisting of multiple pieces of dark-brown soft tissue with soft consistency measuring 60 × 30 × 18 mm was removed.
