The gynecologist's role in preventing overdiagnosis of ectopic molar pregnancy: a case report.

BACKGROUND

Ectopic hydatidiform mole is a rare, yet overdiagnosed, entity. A diagnosis of ectopic molar pregnancy requires close follow-up, has implications on future fertility, and may require chemotherapy. Patients diagnosed with a hydropic abortus do not require hormone surveillance or abstinence from pregnancy for the extended time period generally recommended for patients diagnosed with a complete or partial hydatidiform mole. The correct classification of products of conception is clinically important because each of the three diagnoses has a different potential for malignant transformation.

CASE: A 29-year-old woman, G5P2104, with ectopic pregnancy and without clinical or laboratory data suspicious for molar pregnancy required ancillary histopathologic testing for accurate diagnosis.

CONCLUSION

This case illustrates the vital role of the gynecologist in assimilating information to prevent over-diagnosis of ectopic molar pregnancy. General gynecologists must therefore understand the histopathologic options available for differentiating hydropic products of conception, partial hydatidiform mole and complete hydatidiform mole.
