title: An extremely rare case of gastric subepithelial tumor: gastric endometriosis.
abstract: Endometriosis is a disease characterized by the presence of endometrial tissue outside of the uterine cavity. It is common in women of childbearing age, and is most frequently located in the pelvic cavity. Approximately 10% of endometriosis cases occur outside of the pelvic cavity in locations such as the intestines, genitourinary system, kidneys, lungs, and skin. However, there have been few reports of endometriosis in the stomach. Here, we report a rare case of endometriosis that presented as a subepithelial stomach tumor.
