Disseminated Mycobacterium intracellulare from a Deep Cutaneous Infection.

Primary cutaneous Mycobacterium avium complex (MAC) infection is a rare diagnosis in both immunocompetent and immunocompromised hosts. Disseminated MAC almost always occurs in the setting of advanced HIV infection and typically results from initial pulmonary or gastrointestinal disease. We describe a case of a 70-year-old female with systemic sclerosis and severe tumoral calcinosis that developed disseminated MAC infection secondary to deep cutaneous disease. Treatment was complicated by multiple significant drug interactions, patient comorbidities, as well as an inability to safely and completely surgically resect her infected soft tissue for source control.
