Examinations were made to know the distribution of gross and histopathological lesions in 74 slaughtered swine suspected of atypical mycobacteriosis (in Hamamatsu). Gross lesions first appeared at the mesenteric lymph nodes and extended to the liver, then to the lungs and spleen, and then to the kidneys and somatic lymph nodes. When lesions were present on the lungs and spleen, it was highly probable that histopathologic lesions would be present on the somatic lymph nodes. In some cases, histopathologic lesions occurred on some parenchymatous organs and somatic lymph nodes, even when gross lesions occurred on only one parenchymatous organ. These findings make it clear that, for the sake of correct diagnosis, thorough examinations, including histopathologic tests, must be conducted
