[Morphologic changes of endometrium in patients with ectopic pregnancy]
Objectives:
To study the morphologic changes of endometrium in patients of ectopic pregnancy.
Methods:
The pathologic appearance of endometrium obtained during uterine curettage in 217 cases of ectopic pregnancy in our hospital were analysed retrospectively.
Results:
Seven types of endometrial changes were observed: (1) decidua and/or Arias-Stella (A-S) reaction 147 cases (67.74%), (2) hypersecretory changes 13 cases (5.99%), (3) asynchronous secretory changes between the glands and the stroma 27 cases (12.44%), (4) partial secretory and partial proliferative changes in glands 18 cases (8.29%), a type of small A-S gland was found in 11 of them, (5) early, mid, or late secretory changes 9 cases (4.15%), (6) proliferative changes 2 cases (0.92%) and (7) glandular-cystic hyperplasia 1 case (0.46%). The above morphologic changes of endometrium were correlated with the occurrence and duration of vaginal bleeding and the urinary hCG levels.
Conclusion:
The appearance of decidua and A-S reaction should not be considered the only diagnostic basis for ectopic pregnancy. Patient's history and laboratory findings should also be taken into account in order to acquire an accurate diagnosis.
