The most common form of carcinoma of the stomach is the one presenting a more or less sharply demarcated tumor near the pylorus. Less frequently there is simply a diffuse thickening of the stomach wall with not very sharply defined margins. Occasionally the latter type involves almost the entire extent of the stomach, causing a diffuse thickening of the stomach wall. The former type usually has an ulcerated surface; in the latter often the mucosa remains intact. When there is a very extensive involvement of the stomach in a diffuse growth the term "leather bottle stomach" has been applied, and it is not an inapt descriptive term. Such cases are uncommon, and it seems worth while to place another on record, especially since in this case a large extent of both esophagus and duodenum in addition to almost the entire stomach were involved.
