ectopic decidualization with gross involvement of the peritoneum is one of the rare findings in pregnant women particularly when ectopic decidualization disseminated as an asymptomatic intra-abdominal nodule. we present here a case of an ectopic decidualization in a 33-year-old pregnant woman with symptoms of irritable bowel syndrome during pregnancy.

CONTEXT Decidualization of the endometrium involves the morphological and biochemical reprogramming of the estrogen-primed proliferative endometrial stromal compartment under the continuing influence of progesterone. OBJECTIVES The aim of this study was to evaluate the involvement of the extracellular matrix contractility of eutopic and ectopic endometrial stromal cells during the tissue remo...

The implantation of trophoblast cells at extrauterine sites still results in decidualization. The objective of the present study was to compare decidualization at eutopic and ectopic implantation sites. Tissues from women undergoing elective termination of uterine pregnancy and from women with ectopic pregnancy were used to detect the presence of cells important for the maintenance of pregnancy...

background:   acute appendicitis with appendicial endometriosis is a very infrequently encountered condition during pregnancy. decidualization is the hypertrophy of endometrial stromal cells by the effect of progesterone. similarly, in pregnancy, ectopic stromal endometrial cells in endometriosis can also be transformed by the same mechanism and ectopic decidua (deciduosis) may occur case: here...

Here we describe an unusual case of decidualized endometriosis detected in pelvic lymph nodes. The presence of intranodal ectopic decidua in pregnant women has been described. A few cases of decidualization of endometriotic foci in the pelvic or para-aortic lymph nodes have also been associated with pregnancy. However, decidualized intranodal endometriosis occurring in a postmenopausal woman ha...

The endometrium in early pregnancy undergoes decidualization and functional changes induced by local trophoblast, which are not fully understood. We hypothesized that endometrium from tubal ectopic pregnancy (EP) could be interrogated to identify novel genes and pathways involved in these processes. Gestation-matched endometrium was collected from women with EP (n = 11) and intrauterine pregnan...

BACKGROUND Expression of the tryptophan catabolizing enzyme, indoleamine 2,3-dioxygenase, in the mouse placenta has been shown to be critical in preventing immunological rejection of the fetal allograft. To clarify the physiological importance of indoleamine 2,3-dioxygenase in human pregnancy, we have studied how the expression of this enzyme changes during decidualization of human endometrium ...

The occurrence of decidualization outside the endometrium, is called as ectopic decidual reaction. It can involve any abdominal organs, such ovary, fallopian tube, cervix, uterine surface, omentum, etc. and present grey white nodules. These nodules grossly mimic metastatic disease granulomas, causing a diagnostic dilemma. Decidual reaction benign condition regress spontaneously in postpartum pe...
