Gastric abscess is a localized pyogenic inflammation of the gastric wall, which is a rare form of suppurative gastritis. The rarity of gastric abscess may be associated with the difficulty of early diagnosis and high mortality as a result. In general, subepithelial lesions (SELs) of the stomach are incidentally detected during the course of upper endoscopy without specific clinical symptoms and signs. However, some gastric SELs present rarely as a form of hemorrhage, obstruction, perforation, and abscess. Here we report a 45-year-old man with gastric SEL presenting as a gastric abscess, which was diagnosed as an ectopic pancreas of the stomach, along with a review of the literature. Although gastric SEL presenting as an abscess is known as a serious and life-threatening lesion, the patient made a complete recovery through surgical resection as well as medical treatment.
Core tip: Suppurative gastritis is a rare disorder characterized by a purulent, exudative inflammatory process involving the submucosa that may extend to involve the entire gastric wall and may be divided into two categories: phlegmonous, or diffuse type; and localized, gastric abscess type. Predisposing conditions of phlegmonous gastritis or gastric abscess include alcoholism, diabetes mellitus, decreased gastric acidity, and immunosuppression, such as HIV infection. High mortality rate of suppurative gastritis, between 37% and 84%, has been reported. Medical treatment, such as endoscopic drainage and antibiotics, and surgical resection of the mass should be considered.
