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.
上皮样血管内皮瘤（EHE）是一种罕见的血管源性肿瘤，其特征为细胞增殖，呈内皮、上皮样或组织细胞样。它可发生于任何器官，但在肺和肝脏中更为常见。推荐的治疗方法是手术；然而，在可能为良性的情况下，应采取观察等待的态度。该病例报告了一名71岁女性，因结肠腺癌接受剖腹手术。手术期间，偶然发现胃壁附属处有一个息肉样病变，并将其切除。组织病理学和免疫组化分析确诊为EHE。胃血管肿瘤约占所有胃肿瘤的0.9 - 3.3%。通常预后良好，但由于这些肿瘤的生物学行为处于临界状态，对这些患者进行随访时进行详细的临床评估很重要。
