Synovial Chondromatosis of Distal Radioulna Joint with Features of Lytic Lesion in a 29 years Male: A Case Report and Review of Literature

Abstract

Background: Synovial chondromatosis is a rare, benign condition characterized by proliferation of synovial lining and metaplasia. The disease is usually mono articular and commonly involves knee joint, but it can also occur in shoulder, elbow, hip, ankle and wrist joints. A review of the literature produced 30 case reports of synovial chondromatosis of the wrist with only five cases showing recurrence (5/30, 17%). Because of its low prevalence and nonspecific symptoms, it can present diagnostic difficulties and lead to a delay in treatment. Case: We report a 6 month follow up case of a 29 year old right hand dominant male who presented with complaint of pain and swelling in right wrist joints of four months duration. Plain X-ray revealed lytic lesion at distal end of right ulna with multiple radio opaque deposits. MRI and FNAC were in favour of Synovial chondromatosis. Patient underwent synovectomy and excision of calcific lesion through a dorsoulnar approach and a separate incision over radial styloid under general anaesthesia. Histopathology confirmed the diagnosis of Synovial chondromatosis. Patient had no recurrence till last follow up (6 Month). Conclusion: Synovial chondromatosis of wrist joint is extremely rare. A close coordination between the clinician, radiologist and pathologist is essential for accurate diagnosis and management.
