A diffuse granulomatous inflammation secondary to a trauma of hand: a case report.

Granulomatous inflammation is rare in the musculoskeletal system and difficult to diagnose. Here we describe a case of a 62-year-old woman with a history of being stabbed by a fishbone presented with a soreness, swelling, and limitation of movement of her right palm and wrist for 4 months. Surgery was done and the histopathology of specimens demonstrated granulomatous lesion, which was negative for acid-fast bacilli. This case demonstrates the diagnosis of granulomatous tenosynovitis on MRI, ultrasound, and surgical examination under anesthesia.
