Broad Spectrum of Dermatologic Manifestations Caused by Mycobacterium haemophilum Infection

Abstract

Mycobacterium haemophilum typically infects superficial tissues in immunocompromised persons and can lead to systemic illness. Its natural habitat is unknown, although most cases have been reported from cities near large bodies of water. 1 No cases have been previously reported from the northwestern area of the United States. We report 2 cases of M haemophilum infection that demonstrate the broad spectrum of dermatologic manifestations in varied clinical settings; both cases occurred in the state of Washington.
