[Multifocal carcinoma of the small intestine]

A recently observed case of carcinoma of the small intestine is report because of its rarity and the exceptional nature of polycentrism in these neoplasias. Interest in the case was also due to the onset of carcinoma in a patient who had already undergone gastrosection, a condition which permitted endoscopic diagnosis. The literature did not throw up any other cases of small intestine carcinoma with localization at the afferent loop of a previous gastroenteroanastomosis.
