Hemangiopericytoma is a rare tumor of vascular origin. This tumor has a malignant potential and often recurs or metastasize. A case of primary pulmonary hemangiopericytoma which recurred locally 10 years after the first surgery is presented. The histological appearance of the tumor had some findings of malignant potential in both of the primary and recurrent lesions. We discussed on malignant potential of this tumor in the number of mitotic figures, cellular atipia, and DNA ploidy pattern.
血管外皮细胞瘤是一种罕见的血管源性肿瘤。该肿瘤具有恶变潜能，常复发或转移。本文报告1例原发性肺血管外皮细胞瘤，首次手术后10年局部复发。肿瘤的组织学表现显示原发性和复发性病变均有一些恶变潜能的特征。我们从核分裂象数量、细胞异型性和DNA倍体模式等方面对该肿瘤的恶变潜能进行了讨论。
