Sparganosis is not a common disease. Uncooked snake or frog, infected water and fresh water fish are the usual important source of sparganosis. Most cases of sparganosis are found in subcutaneous or adipose tissue of the abdominal and thoracic wall, and also in the inguinal inguinal regions, but the lesions are rarely found in the breast. We experienced 2 cases of sparganosis in the breast of a 69-year-old female & in the breast of a 37-year-old female. Among them, the 37-year-old female had a history of drinking impure water. The diagnosis was confirmed by surgical excision of the mass, and the plain mammography showed the characteristic finding of an irregular shaped, heterogenous mass lesion. We report here on this case and we briefly review the related literature.
