Studies of the pathologic enlargements of the ileocecal region usually have been confined to the commoner conditions; for example, neoplasms, tuberculosis and other granulomatous processes of definite etiology. Difficulty usually does not arise in establishing the identity of a malignant condition of the cecum. Earlier diagnosis of these lesions is desirable, however. Similarly, the inflammatory swellings of definite etiology, especially tuberculosis and actinomycosis, usually are readily recognized. But there remains a conspicuous absence of early diagnostic signs. A brief review of some of the less common cecal tumefactions seems advisable before our series of cases is presented. Lymphomas occur fairly commonly, but in comparison to carcinomas they are rare lesions. Cinaglia1 considered lymphomas in considerable detail. The closely allied condition lymphosarcoma was recently reviewed by Rankin and Chumley.2 Cholesteatoma is one of the rarest of the cecal tumors. Humiston and Piette3 reported a case in 1921, and
