A rare case of acute gastric mucosal lesions (AGML) accompanied by Gastrosprillum hominis (G. hominis). A 50-year-old Japanese woman had complained of sudden epigastralgia. Endoscopic examina-tion showed AGML which were characterized by several irregular-shaped hemorrhagic erosions in the antrum, and some spotty hemorrhagic erosions in the lower body.
