OBJECTIVE: To study whether nontriploid partial hydatidiform moles truly exist.
STUDY DESIGN: We conducted a reevaluation of pathology and ploidy in 19 putative nontriploid partial hydatidiform moles using standardized histologic diagnostic criteria and repeat flow cytometric testing by the Hedley technique.
RESULTS: On review of the 19 moles, 53% (10/19) were diploid nonpartial moles (initially pathologically misclassified), and 37% (7/19) were triploid partial moles (initial ploidy misclassifications). One additional case (5%) was a diploid early complete mole (initially pathologically misclassified).
CONCLUSION: Nontriploid partial moles probably do not exist: careful reevaluation of putative specimens will probably uncover pathologic or ploid errors in almost all cases.
