Skin and soft tissue infection by Mycobacterium intracellulare in an immunocompetent patient

Nontuberculous mycobacteria (NTM) infections still represent a large group of insidious diseases hard to deal with. Traditionally, immunocompromised patients suffer from NTM infections, especially with respiratory involvement or disseminated diseases due to MAC (Mycobacterium avium complex). Here we report a rare case of Mycobacterium intracellulare infection involving skin and soft tissue, manifested as a chronic cutaneous ulcer in an immunocompetent patient with several comorbidities, including seizures. Accurate diagnosis of species was obtained with in vitro culture and RT-PCR (Real Time-Polymerase Chain Reaction) following a high clinical suspicion. Despite the high complexity of NTM infections, it is possible to achieve diagnostic goals through the appropriate employment of recent DNA-molecular technologies and an adequate management
