Nontuberculous mycobacteria (NTM) are becoming increasingly important cutaneous pathogens as the number of susceptible patients increases. Nevertheless, primary cutaneous infection by one particular species, Mycobacterium avium complex (MAC), remains relatively unusual, particularly in immunocompetent patients. We review the English-language literature on primary cutaneous MAC in patients who were neither immunocompromised nor pharmacologically immunosuppressed. We offer an additional report of a healthy patient who presented to our clinic with primary cutaneous MAC following seemingly innocuous trauma to the leg.
