Disseminated infection caused by nontuberculous mycobacteria (NTM) is very rare, with an incidence of 1.0 to 1.8 cases per 100,000 persons, and typically only occurs in severely immunocompromised hosts. Burn patients suffer a loss of the natural cutaneous barrier as well as injury-induced immune dysfunction, and as a result, commonly develop infections, especially with multidrug-resistant organisms. However, very few NTM infections in burn patients have been reported in the literature. Disseminated NTM infection, in particular, can be a challenge to diagnose in burn patients due to burn-related physiology such as hyperpyrexia and widespread skin injury. We present a case of disseminated infection leading to bacteremia caused by Mycobacterium abscessus in a critically ill burn patient with a 74% total body surface area burn. M. abscessus belongs to the subgroup of NTM known as rapidly growing mycobacteria, which are notable for their ability to form colonies in a matter of days, rather than weeks, and because they are often highly drug-resistant, which complicates antimicrobial therapy. This is the third reported case of bacteremia caused by NTM in a burn patient and the second case that was successfully transitioned from intravenous antimicrobials to an oral regimen.
