A case of low grade hemangiopericytoma of three years duration occurring in the upper end of the femur of a 70 year old man is described. Radiologically, the upper third of the right femur showed a destructive expansile osteolytic lesion with soft tissue extension. The tumour was partially encapsulated. Mitoses were 0-1 per 10 high power fields, suggesting the low grade malignant nature of the lesion. It is felt that all hemangiopericytomas occurring in bone should be considered biologically malignant.
本文描述了一例发生在一名70岁男性股骨上端、病程三年的低度恶性血管外皮细胞瘤。放射学检查显示，右股骨上三分之一处有一个破坏性、膨胀性溶骨性病变，并累及软组织。肿瘤部分有包膜。每10个高倍视野中有0至1个有丝分裂象，提示该病变为低度恶性。认为所有发生于骨的血管外皮细胞瘤均应视为具有生物学恶性。
