(四)卵巢肿瘤的某些组织来源与发生: 1.上皮性肿瘤:包括起源于卵巢生发上皮的肿瘤,卵巢生发上皮为被盖卵巢部分的浆液性腹膜,与腹腔的腹膜同属于间皮性组织。均来源于原始泌尿生殖嵴的体腔上皮。后者又是苗勒氏管的起源,而苗勒氏管又为卵管、宫内膜及宫颈上皮的来源,所以卵巢生发上皮仍为苗勒氏组织系统的组成部分,具有转化为各种苗勒氏上皮的潜能。从肿瘤发生学的观点,生发上皮在陷入卵巢皮质后,可直接
(D) of some ovarian tumor sources and occurrence: 1. Epithelial tumors: including tumors originated in the ovarian germinal epithelium, ovarian germinal epithelium is covered part of the ovarian serous peritoneal, and abdominal peritoneal with the same mesothelioma organization. All originate from the body cavity epithelium of the original urogenital crest. The latter is the origin of Müller’s tube, which in turn is the source of the oviduct, endometrium and cervical epithelium, so the ovarian germinal epithelium is still part of Müllerian’s tissue system and has the potential to be transformed into various Müllerian epithelial potential. From the perspective of oncology, germinal epithelium in the ovary cortex, can be directly
