A cutaneous lesion in a patient with AIDS: an unusual presentation of infection due to Mycobacterium avium complex.
A patient with AIDS developed a purplish, necrotic skin lesion followed by fevers, constitutional symptoms, and watery diarrhea. Stains of samples from the skin lesion and of stool and bone marrow revealed acid-fast bacilli, and Mycobacterium avium was isolated from cultures of these specimens and blood. With the initiation of multiagent oral antimycobacterial therapy, the patient's symptoms abated and the cutaneous lesion reepithelialized. We believe this lesion to be a manifestation of disseminated infection due to Mycobacterium avium complex (MAC). As the population of patients with AIDS who have CD4 cell counts of < 100/mm3 increases, new and unusual manifestations of disseminated MAC infection can be expected. New oral agents with increased activity against MAC may make early recognition and treatment of MAC infections more rewarding.
