Cutaneous nodules secondary to Mycobacterium avium complex in a patient with human immunodeficiency virus.

We present a patient with human immunodeficiency virus who developed multiple painful lesions that previously in the past had speciated as Cryptococcus neoformans cutaneously, and in the lung. Despite induction therapy for presumed re-infection, the patient did not improve so a biopsy was performed and this was speciated as Mycobacterium avium complex, with final diagnosis being disseminated Mycobacterium avium complex. This case highlights the importance of considering a broad differential diagnosis for any new lesions regardless of prior culture data.
