本周病例(2015.7.6—2015.7.12)
1、你考虑什么诊断?
假黄色瘤样输卵管炎(Pseudoxanthomatous salpingitis)
Pseudoxanthogranulomatous salpingitis is a rare disorder characterized by the accumulation of histiocytes containing iron, lipofuscin and hemosiderin in the lamina propria of the fallopian tube, with accompanying chronic inflammatory cells. A recent study of 49 cases indicated a history of endometriosis in 20%, but histologic evidence of endometriosis was identified in the fallopian tubes in 35% and at all sites in 65%. An iron stain was positive in pseudoxanthoma cells lacking hemosiderin in 78%, confirming its close association with endometriosis, often ovarian, as well as IUD use and radiotherapy. It may be due to actively bleeding ovarian endometriosis, which leaks blood into the lumen of the fallopian tube.
2、需要做什么鉴别诊断?
黄色肉芽肿性输卵管炎(xanthogranulomatous salpingitis)、脂质代谢性疾病、血色病等
3、本病预后如何?
本病为良性,输卵管切除即可。但若伴有子宫内膜异位,会导致其他伴随症状。

本期病例比较典型,结合临床病史、组织学形态,必要时辅以免疫组化和特殊染色不难诊断。综合回答思路,rattlebox、nwl123321、月儿yuer加一分,沁园小区累积半分!
