[Eosinophilic granuloma of the ascending colon (author's transl)]

An unusual case of a tumorlike eosinophilic granuloma of the ascending colon is presented. In physical examination, radiographic picture and at operation this tumor appeared suspicious of a malignant obstructive neoplasm, thus leading to the resection of the right colon and to ileocolic anastomosis. Correct diagnosis can be established only by histology.
