Abstract Seventy operated cases of cecal tumor are studied in this report. Carcinoma was found in 56 instances, tuberculosis in 9, chronic inflammation in 2, lymphosarcoma in one, polyposis in one and one of undetermined pathology. Other tumors occasionally found are cyst, gummas, lipomas, tuberculomas, papillomas, cholesyteotomas, liomyomas and actinomycoses. The ileocecal region is the site of predilection for tuberculosis because of the right lymphatic supply. Five of the 9 tuberculosis cases were of the hyperplastic type without a demonstrable primary focus. One had an involvement of the right lung and the cecal growth was considered to be secondary. Three others were tuberculomas. The Friedreich resection was performed in all the tuberculous tumors with no mortality and a symptomatic cure. Only an appendectomy was done in 3 tuberculomas. The cecum has a predisposition to malignant degeneration because of its physiological and anatomical relationship. Regional glandular metastasis was found in 25 per cent, of the cases previously reported. The ileocecal valve was involved in 48 per cent. The signs and symptoms most frequently found were pain, loss of weight, a mass and marked anemia. Roentgen examination was the most accurate aid in diagnosis. The Friedreich operation was the method of choice, being performed in 47 of the 56 cases of carcinoma, with a mortality of 21.4 per cent, in 37 cases reported previously. Of 22 cases since January, 1927, 12 were male, 8 were female and 2 of sex not recorded.
