Mycobacterium avium complex olecranon bursitis in a patient treated with alefacept

Description: We report the first case, to our knowledge, of Mycobacterium avium complex (MAC) olecranon bursitis in a 57-year-old man who was treated with a 12-week course of alefacept for psoriasis. Atypical organisms,including mycobacteria, should be considered in the differential diagnosis of infections developing in patients taking alefacept or in those with a history of recent alefacept use, especially when routine cultures are negative and patients do not respond to conventional antimicrobial therapy.
