Epithelioid hemangioendothelioma of the pancreas presented as massive hematemesis

INTRODUCTION: Hemangioendotheliomas are vascular tumors characterized by the presence of an “epithelioid” or “histiocytoid” endothelial cell. They consist of blood filled spaces mixed with cellular areas that mostly occur in the liver, but other organs can be affected. These lesions cause a wide spectrum of clinical presentations depending on the organ involved. Complete surgical excision is the primary form of treatment; they tend to recur after surgery in some cases. PRESENTATION OF CASE: A-45-year old lady presented with 2 attacks of massive hematemesis. Upper GIT endoscopy was done which showed a vascular tumor arising from the duodenal ampulla, biopsy was not taken because of the risk of bleeding. Laparotomy and duodenotomy were performed, there was a soft irregular 3 cm mass with areas of hemorrhage arising from the duodenum, complete excision was done and frozen section examination showed a benign lesion. Two months later the patient presented with melena and anemia. CT-scan of the abdomen showed a mass at the head of pancreas. Second surgery was done and during surgery a firm mass was found in the region of the head of pancreas, pancreaticoduodenectomy was done and the sample was sent for histopathological examination which showed an epithelioid hemangioendothelioma of the head of the pancreas. DISCUSSION & CONCLUSION: The treatment strategy should be tailored to the individual patient, the clinical presentation, and the rate of progression of the tumor. The natural history of the disease is still poorly understood and there is no uniform treatment form for such tumors.
