title: Actinomycetoma in arm disseminated to lung with grains of Nocardia brasiliensis with peripheral filaments.
abstract: Actinomycetomas represent 97.8% of mycetomas in Mexico, where 86.6% are produced by Nocardia brasiliensis. We report a case of actinomycetoma in the arm by Nocardia brasiliensis disseminated to lung. Uncommon grains were observed which present outside peripheral filaments and also numerous filaments loosing the grains. These characteristics of the grains are due probably because for the long treatment with antibiotics of the patient. In situ antibiotic action against the microcolonies is discussed.
