Two cases of complete hydatidiform mole with coexistent live fetus are presented with special considerations on diagnosis and management. Incidence in the west is 1:10,000 to 1:100,000 pregnancies. These cases are only 2 of the 3 cases diagnosed in the Philippines. Diagnosis can be made by morphology, immunostaining and cytogenetics. Prognosis is unpredictable. Clinical symptoms vary from an aggressive disease requiring termination of pregnancy becuase of high risk of persistent trophoblastic disease or a more stable group that may reach viability. Clinical management should be decided on an individual basis, taking into account the risk to the mother of continuing the pregnancy and the parents wishes. (Author)
