Abstract

Multiple rice body formation is a complication of chronic bursitis frequently associated with seronegative rheumatoid arthritis or tuberculosis. It resembles synovial chondromatosis on imaging and clinically. We report on a pathologically diagnosed multiple rice body formation in subacromial and subdeltoid bursitis in a 44-year-old man who was treated by surgical removal and bursectomy. At 16 months after the removal, range of motion of affected shoulder was normal. No evidence of recurrence of rice body in plain X-ray and ultrasonography. Multiple rice body formed in chronic subacromial and subdeltoid bursitis could be treated with surgical removal and bursectomy successfully.

  Figure 5. Microscopic finding shows a free rice body consists of a collagenous core with interspersed chronic inflammatory cells surrounded by a thin fibrin layer in hematoxylin and eosin stained specimen. There is no evidence of unmineralized metaplastic cartilage. (A) ×20. (B) ×400.
