Abstract:
A case of persistent gestational trophoblastic disease that developed after ectopic (cervical) pregnancy with complete hydatidiform mole (CHM) in a 56-year-old patient is presented. The diagnosis of CHM was made retrospectively based on immunohistochemical analysis of archival material using p57 and Ki67 antibodies. Observation shows the difficulty of objective diagnosis of hydatidiform mole in early pregnancy due to the lack of typical cystic transformation of the stroma of villi, focal proliferation of villous trophoblast. Application of the p57 marker for the differential diagnosis of CHM and other variants of cystic villi transformation may be especially important in cases of ectopic pregnancy, in which morphological changes in the chorion do not always correspond to the classical picture. The presence of ectopic pregnancy with CHM in a 56-year-old patient requires special attention of clinicians.
