Acquired hemophilia A is a rare bleeding disorder with estimated incidence of 1.5 cases/million/year with only 7% of these being post partum. To the best of our knowledge, there has been no case in the literature of acquired post partum hemophilia where an autopsy has been conducted. We present a case of 33-year-old lady who underwent elective caesarean after an uneventful ante partum period and developed fatal complications arising due to post partum hemophilia A characterized by hemorrhage, septicemia, consumptive coagulopathy and multiorgan dysfunction syndrome leading to death.
