Halo Scalp Ring: A Form of Localized Scalp Injury Associated with Caput Succedanum

Abstract

Caput succedaneum is a common birth injury attributed to cervical, uterine, or vaginal pressure on the fetal presenting part. It usually consists of diffuse soft tissue swelling and bruising, which resolve in a few days without sequelae. We have seen two patients who had an unusual alopecic "halo" ring on the scalp associated with a caput succedaneum.
