Abstract

Mycobacteria cause a range of diseases in both immunocompetent and immunosuppressed individuals. An increase in non-tuberculous mycobacterial (NTM) infections targeting skin has been described. Many hypotheses have been developed in order to explain it: the increasing burden of immunocompromised individuals, immigration from endemic countries, improved laboratory identification techniques, and changes inhuman behavior that expose individuals to this NTM. Mycobacterium mucogenicum group comprises M. mucogenicum, Mycobacterium aubagnense, and Mycobacterium phocaicum. This group of organisms was first named Mycobacterium chelonae-like organism in 1982. Most clinically significant cases of those organisms involved catheter-related infections. Nevertheless, we report an interesting patient with a cutaneous infection produced by M. mucogenicum mimicking a squamous cell carcinoma; an excellent response to combined therapy with rifampicin and clarythromicin was observed.
