The authors study 19 personal cases of inflammatory tumour of the caecum and 60 cases found in the world literature over the same period. Without disputing the definition and classification of these inflammatory tumours which were perfectly drawn up by Bremen and Flamand in 1958, they emphasize the difficulty in determining the precise etiology. Struck by the large number of right hemicolectomies carried out for often benign lesions, they propose in order to reduce their number, the use of new investigations, such as selective arteriography, colonoscopy, and attempt whenever possible, to reduce the inflammation by medical treatment.
