Ecthyma gangrenosum-like lesions associated with disseminated nontuberculous mycobacterial infection in an HIV-infected patient.

Ecthyma gangrenosum typically occurs in patients who are immunocompromised. It is most often associated with a Pseudomonas aeruginosa bacteremia but other pathogens can be found. We report an HIV-infected patient with disseminated nontuberculous mycobacterial infection who presented with fever, mucous bloody diarrhea and cutaneous lesions on both legs. The cutaneous lesions had ecthyma gangrenosum feature and the histopathology was compatible with erythema induratum. Hemoculture was positive for nonchromogen slowly growing mycobacteria.
