Breus' mole is a massive, subchorionic, tuberous hematoma formed from maternal blood in the uterus during pregnancy.
Breus mole is reported to be found in the placentas of macerated stillborn foetuses, indicating that massive subchorionic hematoma could have been the cause of their demise.
[2] A massive Breus' mole can cause disturbances in blood flow in the spiral arteries and might result in intrauterine growth restriction of the foetus.
Clinically, Breus' mole may be asymptomatic, or may present with signs of decreased blood flow to the foetus such as growth restriction and foetal distress.
[4] If discovered antenatally, serial USG and/or Doppler scans are indicated to monitor the size of the hematoma and the well-being of the foetus.
