The results from gross and microscopic examination of the stomachs of Lundehunds and examination of stomachs of control dogs from other breeds were compared. Over a 13‐year period, 12 of 14 autopsied Lundehunds have been diagnosed as having intestinal lymphangiectasia. In the present study, histological examination revealed gastritis as manifested by an increase in the number of mononuclear cells infiltrating the lamina propria in all the Lundehunds. The inflammation was chronic and restricted to the fundic and body regions, except in one Lundehund where antral gastritis was also present. Computer‐assisted morphometric analysis was used to quantify the increased number of mononuclear cells. Atrophy of mucosal fundic glands was prominent in most Lundehunds and mucous metaplasia was often present. Conventional morphometry revealed a significant decrease in the height of the gastric mucosa. A relative expansion in area of the basal part of the lamina propria in Lundehunds with chronic atrophic gastritis corresponded to the observed increase in mononuclear cells and stromal elements. Primary gastric carcinoma with neoplastic cells infiltrating layers of the stomach wall was found in four Lundehunds. The high incidence of gastric carcinoma and the consistent presence of gastritis in Lundehunds suffering from intestinal lymphangiectasia suggest that these changes represent features of a single pathogenetic process.
