Lymphocytic gastritis (LG) is a rare form of gastritis characterized by lymphocytosis in the gastric mucosa, while microscopic colitis (MC) is the chronic inflammatory disease of the large intestine with lymphocytic or collagenous colitis as two distinct histologic forms. These lymphocytic disorders of the gastrointestinal tract (GIT) have various associations, commonly gluten-sensitive enteropathy, infection and while others are less commonly associated. We report a case of a 24-year-old patient with concomitant lymphocytic gastritis and microscopic colitis diagnosed via histopathologic analysis of tissue specimens from stomach and colon.
