Gastric epithelioid haemangioendothelioma.
Epithelioid haemangioendothelioma (EHE) is a rare tumour of vascular origin, characterised by celular proliferation, endotelial, epitelioid or hystiocitoid. It may develop in any organ, but it is more common in lung and liver. Surgery is the recommended treatment; however, in case of a potentially benign situation, an expectant attitude should be adopted. The case reports a 71-year-old female who underwent a laparotomy for a colonic adenocarcinoma. During surgery, a polypoid lesion in the dependency of the gastric wall was found incidentally, which was removed. Histopathology and immunohistochemical analysis confirmed the diagnosis of EHE. Gastric vascular neoplasms represent about 0.9-3.3% of all gastric tumours. Usually have a good prognosis, but due to the borderline biological behaviour of these tumours, it is important to have a detailed clinical evaluation at follow-up of these patients.
