Caput Succedaneum

A caput succedaneum presents as a diffuse edematous swelling of the soft tissues of the scalp above the periosteum involving the presenting part of the neonate during delivery.1 It is most frequently seen on the vertex and the occipital midline of the head (Figures 1 and 2). The swelling is pitting in nature, not sharply defined, and usually crosses over cranial suture lines.1 Discoloration of the scalp may occur secondary to petechiae and/or ecchymosis.
