Gordonia spp. are gram-positive bacteria that have previously been reported to cause mycetoma. Here, we report a case of Gordonia soli (initially misidentified as Nocardia spp.) as the etiological agent of actinomycetoma in a 64-year-old patient. After a literature search in the Cochrane Library, LILACS, SciELO, MEDLINE, PubMed, and PubMed Central databases, we concluded that this is the first case report of mycetoma caused by Gordonia soli. The current case highlights the importance of microbiological diagnosis of mycetoma and the challenges in its management.
