Phlegmonous gastritis is a rare complication of endoscopic procedures, or may occur in the fetus [ 1 ]. Two cases have been reported: one followed India ink marking and the other followed polypectomy [ 2 ] [ 3 ]. Several conditions can predispose to the development of phlegmonous gastritis, including conditions associated with reduced immune response, gastrointestinal bleeding, and abdominal surgery [ 4 ] [ 5 ]. We encountered a case of phlegmonous gastritis and report it here because of its rarity.
