Background: We have assessed gastroduodenal, endoscopical and histopathological findings in a series of patients with microscopic colitis (MC).

Methods: We studied 75 patients with MC, 27 with collagenous colitis (CC) and 48 with lymphocytic colitis (LC), and 60 controls. Data of endoscopical findings were collected and biopsies were assessed.
