| 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, 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 |
