Caput succedaneum

Alternative names:

caput

Definition:

A diffuse swelling of the scalp in a newborn; occurring after a head first (vertex) delivery.

Causes, incidence, and risk factors:

A caput succedaneum is caused by the mechanical trauma of the initial portion of scalp pushing through the initially narrow cervix. The swelling may be on any portion of the scalp, may cross the midline (as opposed to a cephalhematoma) and may be discolored because of slight bleeding in the area. There may also be molding of the head, which is common in association with a caput succedaneum.
