Angiosarcomas are malignant neoplasms that originate from endothelial cells. The symptoms exhibit a non-specific nature, and achieving a preoperative diagnosis is frequently challenging. They are seldom encountered in the abdomen, and their occurrence in the pancreas is even rarer. Here we document a 67-year-old man with pancreatic angiosarcoma and analyse the literature to outline the clinicopathologic characteristics of this rare phenomenon. This patient with family history of pancreas cancer presented with abdominal pain, and the CT-scan revealed a 4 cm mass at the neck of the pancreas but CA19-9 was normal. Radiologic findings were unusual for ordinary pancreas cancer. Fine-needle aspiration biopsy through endoscopic ultrasound revealed "undifferentiated malignant cells for which the diagnosis of "carcinoma" was favoured. Total pancreatectomy, splenectomy and portal vein reconstruction were performed and epithelioid angiosarcoma were diagnosed. Despite an uneventful postoperative period, discharge on postoperative day 8 without any complications, as well as diligent post-discharge clinical care, the patient died 65 days postoperatively, attributed to the presence of extensive metastasis. A comprehensive literature search has identified a limited number of documented cases of primary pancreatic angiosarcoma, with only ten cases reported to date. Pancreatic angiosarcomas are very rare and prone to misdiagnosis. The formation of a more demarcated but high-grade tumour with necrosis is a feature that distinguishes angiosarcomas from ordinary carcinomas of this organ. Pathologic diagnosis is also highly challenging closely resembling undifferentiated carcinomas. Angiosarcomas are highly aggressive when they occur in the pancreas. Prompt diagnosis at an early stage is crucial as surgery with curative intent serves as the primary treatment approach.
