    Abstract:
    Pyloric gland adenoma (PGA), also called adenoma with gastric differentiation, is a rare neoplasm of the gastric mucosa that can appear as gastric heterotopia in several organs. A 49-year-old woman presented with gastric reflux and chronic elevation of liver enzymes. She had a history of type 2 diabetes mellitus, hypothyroidism and an unspecified allergy treated with deflazacor, and a family history of autoimmune diseases. A liver biopsy showed macro- and microvesicular steatohepatitis. Hepatitis B and virus serum tests were negative. Autoimmune hepatitis was suspected and investigated. As an evaluation for dyspeptic symptoms an upper gastrointestinal endoscopy was performed, showing diffuse gastroduodenitis. A few polyps were found and resected from the gastric fundus; histopathology revealed a pyloric gland adenoma. There is very few clinical data on this tumor type because it is frequently underdiagnosed and reported as dysplasia. Further research is needed on the pathophysiology of this disease.
