血管外皮细胞瘤甚少见,仅占全部血管性肿瘤的1％强。该肿瘤发生于耳鼻咽喉科领域内者更少,自1949年Stout报告的病例中有两例分别生长在口咽和鼻部以来,连同本文报告的一例,迄今文献中仅得14例。作者报告的患者为一男性,61岁,肿瘤发生于右筛窦和鼻腔,经手术切除加钴疗后,观察一年半,无残留,复发或转移。本病原因不明,可能与外伤或长期使用类固醇激素有关。组织学上发源于毛细血管及毛细血管后微静脉周围的圆形或梭形的外皮细胞。可发生于任何年龄,但以50～60岁居多。无性别差异。约1/3病例发生于头颈部,其大小随肿瘤所在部位而异。发生于鼻部的有报告其大达21.5×1.7×1.3cm者,临床表现因肿瘤大小及其所在部位而定。肿瘤呈局限性,结节状、硬而无痛。肿瘤本身并不含神经,但当其压迫局部神经末梢 Hemangiopericytoma is rare, accounting for only 1% of all vascular tumors. There are even fewer cases of this tumour occurring in the otolaryngology area. Since two of the cases reported in Stout in 1949 have been found in the oropharynx and the nose, together with one case reported in this paper, only 14 cases have been reported to date in the literature. The author reported that the patient was a male, 61 years old. The tumor occurred in the right ethmoid sinus and nasal cavity. After surgery plus cobalt treatment, the patient was observed for one and a half years without residual, recurrence or metastasis. The cause of the disease is unknown and may be related to trauma or long-term use of steroid hormones. Histologically arises from the circular or fusiform epithelial cells surrounding the capillaries and capillaries behind the venules. Can occur at any age, but mostly 50 to 60 years old. There is no gender difference. About one-third of cases occur in the head and neck, and their size varies with the location of the tumor. Occurrences in the nose are reported to be as large as 21.5 x 1.7 x 1.3 cm, and the clinical manifestations are determined by the size of the tumor and its site. The tumor was localized, nodular, hard and painless. The tumor itself does not contain nerves, but when it oppresses local nerve endings
