Mycobacterium marinum infection in a patient with the acquired immunodeficiency syndrome.

A variety of mycobacterial organisms may infect patients with acquired immunodeficiency syndrome. A patient with acquired immunodeficiency syndrome, lymphoma, and sporotrichoid Mycobacterium marinum is described. The patient responded completely to antimycobacterial therapy but relapsed when he discontinued his medications six months into his course. Disease persistence in spite of therapy had been noted in other immunocompromised states but not previously in acquired immunodeficiency syndrome. Patients with acquired immunodeficiency syndrome may require prolonged treatment or suppressive therapy for Mycobacterium marinum infections.
