title: Gestational trophoblastic neoplasia following molar ectopic pregnancy: a case report.
abstract: BACKGROUND
  Ectopic molar pregnancy is a gestational trophoblastic disease (GTD) of rare occurrence and therefore not always remembered as a diagnostic possibility.
  
  
  METHODS
  We describe a case of molar ectopic pregnancy in a primiparous woman who developed gestational trophoblastic neoplasia and required chemotherapy to achieve remission.
  
  
  CONCLUSIONS
  This case stresses the important role of histopathologic examination in establishing a diagnosis of ectopic molar pregnancy. Moreover, close follow-up of human chorionic gonadotropin levels is required when a GTD is suspected.
