Manson’s sparganosis, which can affect any of various sites of the body, was recognized as a breast mass in a 66-year-old woman. The infection manifested as a breast mass measuring 13 mm in diameter detected by ultrasonography and mammography. Breast cancer was suspected initially and the microbe was detected by fine needle aspiration. Hematological and immunoserological examinations revealed no significant abnormalities. Since this disease is generally transmitted by the intake of unboiled water or raw meats, including of snakes, chickens, etc., the dietary history is useful for the diagnosis. In our patient reported here, the route of infection could not be ascertained, because she gave no history of drinking unboiled water or consuming raw meat.
