Umbilical cord hematoma describes the formation of a hematoma secondary to bleeding from the umbilical cord.


The hematomas can be either spontaneous or iatrogenic. Spontaneous bleeding is very rare and documented to be around 0.02% of pregnancies. Majority of the cases are iatrogenic related to procedures like cordocentesis.
