Abstract:
A male patient in his 70s was admitted with bloody stool. Upper gastrointestinal endoscopy revealed active bleeding from a submucosal lesion located opposite the duodenal papilla. Hemostasis was difficult to achieve, and histopathological analysis of the biopsy specimen revealed only necrotic tissue and inflammatory changes. Endoscopic ultrasonography (EUS) revealed a 35-mm hypoechoic lesion within the submucosal layer. EUS-guided tissue acquisition suggested a poorly differentiated or undifferentiated tumor. Given these findings, the patient underwent pancreaticoduodenectomy. The final diagnosis was primary duodenal epithelioid angiosarcoma.
