Granulomatous gastritis and Whipple's disease.

Granulomatous gastritis is an uncommon morphological diagnosis. An etiopathogenetic diagnosis can be reached only by combining the morphological examination with clinical and laboratory investigations. The diagnosis of Whipple's disease in our patient was based upon a classical clinical picture and upon the likewise classical morphological appearance of the small intestinal mucosal biopsy. To our knowledge, this case report is the first to describe granulomatous gastritis in a patient with Whipple's disease.
