Code Diagnosis Comment Score
anonymous Endometrium with decidual change and Arias-Stella reaction (100%). To exclude ectopic pregnancy.  100
anonymous Abortion (Epithelial inclusion seen, favor Biotin inclusion(not herpes simplex), suggestive of gestational endometrium) nil  100
anonymous Haemorrhagic and necrotising decidua. No evidence of chorionic villi or placental site reaction. 1. Embed all the tissue. 2. Look for pregnancy outside the uterus. 3. Exclude endogenous and exogenous hormonal intake.  100
anonymous Decidua and Arias-Stella reaction (100%) nil  100
anonymous ARIAS-STELLA REACTION The possibility of vascular lesions of the decidua should be excluded by clinical correlation and more sampling.  100
anonymous Decidua. 100% Embed all the whole specimen.  100
anonymous Decidua, focal Arias-Stella reaction. No chorionic villi 100% nil  100
anonymous Decidua and Arias Stella reaction nil  100
anonymous Decidua, Arias-Stella Reaction nil  100
anonymous Decidualized endometrium with focal Arias-Stella phenomenon, with hemorrhage, exudation and presence of few cells suggestive of intermediate trophoblastic cells suggestive of intrauterine pregnancy. Need to do, betaHCG, hPL, cytokeratin for confirmation.  100
anonymous Decidua Please correlate with clinical history and pregnancy test result.  100
anonymous Decidua, no products of gestation May need to embed all tissue to look for products of gestation  100
anonymous Decidua and gestational type endometrium, no products of gestation or placental site reaction detected (100%). Correlate with clinical findings to exclude the possibility of extrauterine pregnancy.  100
anonymous Decidua and Arias-Stella reaction, take more blocks to look for chorionic villi and need to exclude ectopic pregnancy (100%Probability). nil  100
anonymous Decidual tissue 100% Correlate with clinical history to rule out ectopic pregnancy, or hormonal effect.  100
anonymous Decidua with Arias-Stella reaction. No definite POG Consider additional sampling for presence of POG  100
