Clinically and pathologically, it closely resembles partial molar pregnancy and complete hydatidiform mole with a coexistent healthy fetus, both of which are associated with malignant trophoblastic disease. PMD, however, has no risk of malignant trophoblastic disease and can result in the birth of a normal fetus, highlighting the need for clinician awareness of PMD in order to avoid unnecessary termination of a viable and potentially healthy fetus.<\/jats:p>","DOI":"10.1097\/01.jaa.0000527704.93074.1a","type":"journal-article","created":{"date-parts":[[2017,12,27]],"date-time":"2017-12-27T17:50:16Z","timestamp":1514397016000},"page":"36-40","source":"Crossref","is-referenced-by-count":10,"title":["Cystic
