“…Pneumonia, with or without pleural empyema, and soft-tissue abscesses represent uncommon complication of NTS infection, accounting for 10% [4] and from 3.7% [3] to 7.3% [5], respectively, of extra-intestinal focal infections. To the best of our knowledge, chest wall abscesses caused by non-NTS have been reported only in 6 patients between 1990 and 2011: 4 of them had no underlying disease or predisposing condition [11–14] and 2 patients had AIDS [15,16]. Most extra-intestinal localizations of NTS infections develop in pediatric patients and in patients with underlying diseases or predisposing conditions, such as malignancies, diabetes mellitus, immunosuppressive therapies, liver cirrhosis, renal insufficiency, or HIV infection [4–9].…”
