Hemangiopericytoma is a vascular tumor originating from the pericytes which surround the capillaries. The tumor occurs anywhere in the body preferably at head and neck and the extremities. In less than 3% it grows in the stomach. In spite of surgical excision local recurrence or hematogene metastases must be expected. We report a case of primary hemangiopericytoma of the stomach which could only be diagnosed by metachrone liver metastases. This case shows that hemangiopericytomas and their metastases belong to the differential diagnosis of cystic liver lesions. Diagnostic procedure, therapy and prognosis of this rare tumor is discussed by an analysis of the literature.
血管外皮细胞瘤是一种起源于围绕毛细血管的周细胞的血管肿瘤。该肿瘤可发生于身体的任何部位，以头颈部和四肢最为常见。不到3%的病例发生在胃部。尽管进行了手术切除，但仍可能出现局部复发或血行转移。我们报告一例胃原发性血管外皮细胞瘤，仅通过肝转移才得以诊断。该病例表明，血管外皮细胞瘤及其转移瘤属于肝囊性病变的鉴别诊断范畴。通过文献分析讨论了这种罕见肿瘤的诊断方法、治疗及预后。
