What term describes the newborn skull condition where the scalp shows diffuse edema due to birth pressure and crosses suture lines?

• A. Caput succedaneum
• B. Cephalohematoma
• C. Moulding
• D. Mongolian spot

Answer: (A)

Caput succedaneum is diffuse swelling of the scalp caused by pressure during birth. Because it involves the soft tissues over the skull, the edema crosses suture lines, which helps distinguish it from other conditions. It’s typically present at birth and resolves within a few days without intervention. This sets it apart from cephalohematoma, which is a collection of blood beneath the periosteum and does not cross suture lines, often taking longer to resolve. Moulding refers to temporary shaping of the skull bones during delivery, not diffuse edema, and Mongolian spot is a benign skin pigment variation unrelated to the skull.
