Not every vascular finding on newborn skin is an innocent nevus simplex. While stork bites are benign, parents and clinicians should know the subtle signs distinguishing simple birthmarks from true vascular tumors or deep midline malformations.

Port-wine stains (nevus flammeus) look flat and pink at birth, resembling nevus simplex. However, port-wine stains typically present unilaterally, cross distinct sensory nerve distributions across the face (such as the V1 ophthalmic branch of the trigeminal nerve), and do not fade. These true capillary malformations can correlate with Sturge-Weber syndrome, a neurocutaneous disorder that requires pediatric ophthalmology and neurology evaluations to monitor for glaucoma and vascular abnormalities in the brain.

Infantile hemangiomas present another common scenario. Though often flat at birth, these rapidly proliferating vascular tumors grow into raised, bright red plaques over the first 3 to 6 months. While most resolve without intervention, hemangiomas near the airway, eye, or lips demand prompt assessment to determine if oral propranolol therapy is necessary. By contrast, a faint, symmetrical pink patch on an infant's nape or between the eyebrows requires no interventions, no detox regimens, and no genetic investigations.
