case_images: Hematological parameters, as well as radiographs of the right wrist and hand, were normal (Fig. 1).

case_images: A tenosynovial mass around the flexor tendons located along the carpal tunnel at the level of the distal radioulnar joint, suggestive of PVNS, was discovered on magnetic resonance imaging (MRI), which was performed to further assess the cause of any underlying pathology (Fig. 2).

case_images: Under close supervision, the dissection was continued until the transverse carpal ligament was released (Fig. 3).
case_images: Photomicrograph (high power 40x magnification) showing multiple synoviocytes with an inconspicuous cytoplasm and round central nuclei, with hemosiderin deposition in a few cells.

case_images: Macroscopic findings showed a yellowish-brown colored mass with few nodules and fibrous septae in between, and microscopic findings showed multiple synoviocytes with an inconspicuous cytoplasm as well as round central nuclei, with hemosiderin deposition in a few cells (Fig. 4).
