The lesions observed in the histopathological study consisted of lymphadenitis and pyogranulomatous pneumonia, with necrosis, mineralization, abundant multinucleated giant cells (some of Langhans), and a moderate amount of eosinophilic polymorphonuclear leukocytes. Although these lesions are not the most characteristic of tuberculosis, no structures compatible with parasites, fungi or bacteria could be observed and tuberculosis could not be ruled out. The microbiological culture allowed to isolate an abundant growth of Corynebacterium pseudotuberculosis, it was therefore a case of Caseous Lymphadenitis.
