Congenital (infantile) hemangiopericytoma is a rare soft-tissue tumor that has been described as a distinct subtype of the classic hemangiopericytoma. We report the ultrastructural, immunocytochemical, and flow cytometric features of a case diagnosed in a male neonate 3 days after birth. The tumor appeared structurally similar to its adult counterpart, meriting the designation hemangiopericytoma, but the improved prognosis that has been reported in young children supports according the infantile form the status of an entity rather than merging it with its adult counterpart.
先天性（婴儿型）血管外皮细胞瘤是一种罕见的软组织肿瘤，已被描述为经典血管外皮细胞瘤的一种独特亚型。我们报告了一例出生3天后诊断出的男性新生儿病例的超微结构、免疫细胞化学和流式细胞术特征。该肿瘤在结构上与其成人对应物相似，值得命名为血管外皮细胞瘤，但据报道幼儿预后较好，这支持将婴儿型视为一个独立的实体，而非将其与成人对应物合并。
