Key words: gastric foreign body, hemorrhagic gastric ulcer, rice cake

A 62-year-old man visited our hospital because of epigastric pain and black stools. He had a history of successful Helicobacter pylori eradication. Computed tomography (CT) revealed a 33-mm diameter mass in the stomach (Figure 1A). Esophagogastroduodenoscopy revealed a solid, whitish object (Figure 1B) and two gastric ulcers in the antrum (Figure 1C). One of the ulcers had a visible vessel (Figure 1D), and hemostatic clips were applied. The whitish object was thought to be hardened rice cake because of its high density on CT (1) and his history of swallowing a whole rice cake one month ago. We cut the rice cake into pieces with a snare and retrieved it. Thereafter, his symptoms rapidly resolved.

A freshly-cooked rice cake is soft and viscous. However, it solidifies at body temperature and may not pass through the pyloric ring if a large piece is swallowed. In the present case, the rice cake had stagnated for a month, and hemorrhagic gastric ulcers developed because of the mechanical stimuli (1).
