侵袭性骨化纤维瘤临床少见,文献上曾用过多种不同命名,如侵袭性骨样骨瘤、侵袭性幼年骨化纤维瘤、侵袭性纤维结构不良、小梁状韧带样骨母细胞瘤等。为探讨其肿瘤生物学特性及复发的可能原因,本文报告1例,对其电镜观察予以介绍。 患者 男,49岁。主因左眼球突出3个月于1992年9月收住我科。查体:左中鼻甲骨质增生、变硬,左眼球向前外方突起,X光片(图1)显示左筛窦前后组密度增高影。采用额筛窦手术进路,见筛窦被 Invasive ossifying fibroids are clinically uncommon and many different names have been used in the literature, such as aggressive osteoid osteoma, invasive juvenile ossifying fibroma, poorly constructed invasive fibrous structures, trabecular ligament-like osteoblastoma Wait. In order to explore the biological characteristics of the tumor and the possible causes of recurrence, we report 1 case and introduce its electron microscope observation. Male patient, 49 years old. Mainly because of left eyeball prominent 3 months in September 1992 to accept our department. Physical examination: left middle turbinate bone hyperplasia, harden, the left eyeball forward protrusion, X-ray (Figure 1) shows the left ethmoid before and after the group increased density shadow. The amount of ethmoid sinus surgery approach, see the ethmoid
