title: Primary extraskeletal Ewing sarcoma of the stomach: a rare disease in an uncommon location.
abstract: We report the case of a 63-year-old female undergoing evaluation of symptomatic anemia, gastroesophageal reflux disease, and abdominal pain. After a thorough diagnostic workup, a large, ulcerated mass was identified in the patient's stomach, and surgical pathology in combination with molecular analysis yielded a diagnosis of primary extraskeletal Ewing sarcoma. In our report, we discuss the epidemiologic, clinicopathologic, and radiographic features of this rare disease and provide a review of the existing literature.
