Septic arthritis due to Mycobacterium avium complex (MAC) is extremely rare. While MAC infection is classically associated with HIV/AIDS and immunosuppressed states, it may occur in immunocompetent individuals. We report a case of MAC septic arthritis of a native wrist joint in an immunocompetent host. The diagnosis of septic arthritis due to MAC is commonly delayed and initially misdiagnosed, warranting a high level of suspicion to make an accurate and timely diagnosis. Suspecting the diagnosis when there are atypical features present in the clinical history may be crucial in identifying affected patients.
