Abstract: Rice bodies are known to form in patients with certain inflammatory conditions such as rheumatoid arthritis and seronegative inflammatory arthritis. However, in this article, we focus on the infectious causes of tenosynovitis of the hand, especially mycobacterial infections, and the importance of diagnosis before treatment, especially before a steroid injection is given. We present a patient with tenosynovitis of the flexor tendon of the third finger who underwent an incision and drainage procedure. During the operation, multiple soft white beads were discovered and identified as rice bodies. Cultures of the specimen were positive for Mycobacterium avium intracellulare.
