AB Molar  pregnancy  is  part  of  a  spectrum  of  gestational  trophoblastic  tumors  that  include  benign  hydatidiform  moles,  locally  invasive  moles,  and  choriocarcinoma.  The  classic  clinical  presentation  is  painless  first-trimester  or  early  second-trimester  vaginal  bleeding  with  a  uterine  size  larger  than  the  estimated  gestational  age  based  on  the  last  menstrual  period.  Signs  of  preeclampsia  (hypertension,  headache,  proteinuria,  and  edema)  in  the  1st  trimester  or  early  2nd  trimester  are  highly  suggestive  of  this  diagnosis  as  well.  Hyperthyroidism  is  found  in  roughly  5%  of  cases.  Acute  respiratory  distress  may  occur  due  to  embolization  of  trophoblastic  tissue  into  the  pulmonary  vasculature,  thyrotoxicosis,  or  simple  fluid  overload.
