Rapidly Growing Mycobacterial Infections of the Skin and Soft Tissues Caused by M. fortuitum and M. chelonae

Purpose of Review Non-tuberculous mycobacteria (NTM) have emerged as pathogens of clinical importance in human health as etiological agents of opportunist infections. Although NTM are known to cause systemic infections in immunocompromised subjects primarily in HIV patients, yet the growing number of immunosuppressed patients with new therapies and even more recently in non-immunocompromised subjects often localized infections of the lungs or skin and soft tissues (S&STI) but with a new clinical spectrums. Our goal is to report distinct patterns of infections according to the clinical and immunological settings and management options.
