[Primary neoplasms and hyperplasias of the gastric mucosa in the dog].
During the past 15 1/2 years (from 1969 to the middle of 1984) 35 canine primary gastric neoplasms (32 necropsies and 3 partial gastric resections) were examined. Brought into relation with the total number of necropsies carried out in dogs (12,494) the incidence of stomach tumours in the dogs is 0.3%. The tumours are classified as 12 benign (1 adenomatous polyp, 11 leiomyomas) and 23 malign neoplasms (20 carcinomas, 3 sarcomas). In addition a circumscribed hyperplasia of the gastric mucosa is reported. The average age of the dogs with carcinomas is 8.9 years. The tumours were most frequently located in the pyloric region and combined with ulcerations. Most of them had metastases. According to a classification of human gastric carcinomas, which also is applied to animals, 18 tumours are of the "diffuse type", two of the "intestinal type". The described cases are compared with corresponding data of the literature. The pathogenesis and the etiology of gastric carcinomas are discussed.
