Successful management of Mycobacterium haemophilum lower extremity cutaneous infection in a matched-unrelated donor stem cell transplant recipient

Nontuberculous mycobacterial infections can often occur in individuals with adequate immune function. Such infections typically have cutaneous involvement and are caused by rapidly growing mycobacterium. Other nontuberculous mycobacteria species, like Mycobacterium haemophilum, almost always present as opportunistic infections occurring in severely immunocompromised hosts. Here, we present a complicated and protracted course of diagnosing M.haemophilum lower extremity cutaneous infection in a matched-unrelated donor stem cell transplant recipient.
