Nevus simplex
Pronunciation: NEE-vus SIM-pleks
A common vascular birthmark in neonates caused by capillary ectasia, typically appearing on the nape, glabella, or eyelids; also called a 'stork bite' or 'angel kiss.'
Full Definition
Nevus simplex is the most prevalent vascular birthmark in newborns, presenting as a flat, pink-to-red patch resulting from dilated dermal capillaries. Lesions on the face (often called 'angel kiss') typically fade within the first two years of life, while nuchal lesions (often called 'stork bite') may persist into adulthood. It requires no treatment and is clinically distinguished from port-wine stains by its tendency to blanch fully and its lack of progressive darkening. Editors must be careful not to conflate the colloquial names with the clinical term 'nevus simplex' in formal documents.
Usage
Usage note: The colloquial terms 'stork bite' and 'angel kiss' are acceptable in patient-education materials but should be replaced by 'nevus simplex' in clinical or formal editorial contexts.
