摘要
眼眶血管外皮瘤２０例，其病理特点为：丰富的血管网，血管之间大量增生的梭形细胞，单个瘤细胞外有网状纤维包绕。根据肿瘤的异形程度及核分裂的数量诊断为良性、低度恶性及恶性血管外皮瘤，１０岁以下患者诊断恶性要慎重。良性者局部切除应彻底，以防复发，恶性者应尽早行眼眶内容剜出术。放射治疗效果不肯定。本组病例平均随访６．３年，随访率１４／２０（７０％）．死亡率３／１４（２１．４％），健在者９例，存活最长者１６年。
The clinical and pathologic aspects of twenty cases of orbital hemangiopericytomas are reported. In histopathology the tumors were characteristically full of blool vessels, between which there were abundant prolliferative spindle cells surrounded by reticular fibers. The benign and malignant tumors were differentially diagnosed accoring to the degree of cellular atypia and number of mitosis. Diangosis of malignant hamangiopericytoma should be made with caution for children under ten. The benign tumors should be completely resected while for malignant ones the enucleation must be performed as early as possible. The effect of radio therapyremains to be uncertain. In this series, 14 patients have been followed for an average of 6. 3 years, among them 3 died (21.4%),the longest duration of survival was 16 years.
