Neonatal cephalic pustulosis
Pronunciation: nee-oh-NAY-tal seh-FAL-ik pus-tyoo-LOH-sis
Also written as: NCP — Neonatal cephalic pustulosis
A benign self-limiting eruption of papules and pustules on the face and scalp of neonates, associated with Malassezia colonisation and often confused with neonatal acne.
Full Definition
Neonatal cephalic pustulosis (NCP) is characterised by inflammatory papules and pustules confined to the face, scalp, and neck of neonates typically presenting in the first weeks of life. It is thought to represent an inflammatory response to Malassezia species rather than true acne, and lacks the comedones that characterise neonatal acne vulgaris. NCP is self-limiting and usually resolves without treatment, though topical antifungals are occasionally used. Editors should distinguish NCP from neonatal acne: the absence of comedones is the key differentiating feature and should be reflected accurately in clinical documentation.
Usage
Usage note: Distinguish carefully from 'neonatal acne' in any editorial context: comedones are absent in NCP. NCP acceptable as abbreviation after first definition.
