The aim of the present study was to summarize the clinical characteristics of nocardiosis caused by Nocardia otitidiscaviarum in order to improve the knowledge of nocardiosis. A case of dissemination nocardiosis caused by N. otitidiscaviarum in an immunocompetent host is reported and the associated literature reviewed. Informed consent for publication of this case report was provided by the patient. The present patient was a young immunocompetent man suffering from disseminated nocardiosis induced by infection with N. otitidiscaviarum. Following a poor response to β‑lactam antibiotic, a combination of sulfonamide with minocycline was administered, which successfully ameliorated the symptoms. Previous studies published in English were retrieved from PubMed with ̔Nocardia otitidiscaviarum̓ used as the search keyword. A total of 23 articles were retrieved from the PubMed database, supporting the assertion that N. otitidiscaviarum is a rare Nocardia species. Among these 23 cases, there were 11 cases of lymphocutaneous (48%), 5 of pulmonary (22%), 2 of brain (9%) and 1 of pyothorax (4%) infection, and 4 cases of disseminated infections (17%). Analysis of the immune state of these patients demonstrated that 9 were immunocompetent (39%), 7 of whom had cutaneous infections (30%) with a predominant history of trauma (6/7), and 14 were immunosuppressed, 9 of whom were treated with prednisolone. Microbiology and histopathology were necessary in all cases for definite diagnosis. Among th...
