Although nontuberculous mycobacteria (NTM) infection is often thought of as a pulmonary disease, it can manifest on the skin in rare cases. In this report, we describe two cases of cutaneous
Mycobacterium szulgai
that presented as nonhealing rashes that were initially thought to be caused by bacterial cellulitis but did not respond to broad-spectrum antibiotics. In both cases, the rash began on the upper extremities. We believe that these cases will be of interest as they demonstrate a rare cutaneous infection and an unusual presentation for NTM. It is important to consider NTM, and
M. szulgai
specifically, in an immunocompromised patient with a nonhealing rash and initiate appropriate diagnostic studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
