Microscopic evaluation
Molar pregnancy is evidenced by:[1]
- Heterogeneity in villous size with one one hand large, hydropic villi, and small, fibrotic villi on the other.
- Enlarged villi being irregularly shaped with scalloped borders and trophoblastic pseudoinclusions, and sometimes cistern formation
- Trophoblastic hyperplasia
In case of molar pregnancy, perform immunohistochemistry for p57. p57 negative cases with molar morphology are diagnosed as complete hydatidiform moles without genotyping. p57+ cases should be subjected to genotyping.[2]
