Gastric wall endometriosis in a postmenopausal woman

Endometriosis is the presence of endometrial tissue outside of the uterus. It is common in women of childbearing age, and is frequently located in the pelvic cavity. Approximately 10% of endometriosis cases occur in extrapelvic locations. However there are few reports of gastric wall endometriosis. Here, we report a rare case of endometriosis in postmenopausal woman. The patient presented with epigastric pain. The investigations included ultrasound (US) and contrast enhanced computed tomography (CECT) where she was diagnosed with gastric wall neoplasm. She underwent surgery where the mass was excised. The histopathological examination surprisingly came with the diagnosis of gastric wall endometriosis.
