【摘要】 本文对心脏粘液瘤做了35例光镜和8例电镜观察。认为:(1)该肿瘤是真性肿瘤,来源于心内膜细胞;(2)该肿瘤细胞不超过弹力板。但是,该瘤细胞属于活跃性细胞,瘤体内有幼稚低分化细胞存在。瘤蒂小动脉穿过弹力板深达肌层,小动脉与粘液瘤细胞产生有关,故手术时应力求将瘤蒂连同周围组织0.5～1.5厘米和卵圆窝组织全层切除。更多还原

【Abstract】 35 cases of cardiac myxoma were examined by the light microscop andelectron microscops Some ideas of the report are: 1. Cardiac myxoma repre-sent true neoplasm. 2. The tumor cells does not invade the elastic layer, butthere are some young and lower differential cells with active character in theneoplasm. The small arteries of the tumor stalk penetrate elastic layer intothe myocardium. However, the development of the tumor cells may be relatedto the endothelial cells of the small arteries in tumor stalk. The authorsemphasize that the tumor must be excised together with the tumor stalk, inc-luding the neighboring area of atrial sept ranging from 0. 5-1. 0 cm duringoperation.更多还原
