Complications

While nevus simplex itself is benign, it can sometimes be associated with other conditions. For instance, midline lumbosacral nevus simplex, sometimes called a butterfly-shaped mark, may indicate spinal dysraphism if accompanied by other local skin anomalies. Nevus simplex can also occasionally be observed in infants with genetic syndromes such as Beckwith-Wiedemann syndrome, macrocephaly-capillary malformation syndrome, and others. However, these associations are rare, and the presence of nevus simplex alone does not necessarily indicate these conditions.
In cases where nevus simplex is associated with other anomalies, further evaluation and diagnostic testing may be necessary. Imaging studies such as ultrasound or MRI can help identify any underlying conditions that may require treatment. It is important for healthcare providers to consider these potential associations and to conduct a thorough evaluation when additional risk factors are present.
Cosmetic Concerns
For lesions that persist into adulthood, particularly on visible areas such as the face or neck, cosmetic treatments like laser therapy can be considered to reduce their appearance. It is important to discuss these options with a dermatologist to understand the potential benefits and risks.
Laser therapy can effectively lighten the color of persistent nevus simplex lesions, making them less noticeable. This treatment is generally safe and well-tolerated, with minimal side effects. However, it is important to have realistic expectations and to understand that multiple treatment sessions may be required to achieve the desired results. Consulting with a dermatologist who specializes in laser treatments can provide valuable guidance on the best approach for managing persistent nevus simplex.
Prevention
Reducing Risk
There is no known way to prevent the appearance of nevus simplex or other birthmarks. These vascular malformations are a normal occurrence in newborns and are present in a significant proportion of infants.
Since nevus simplex is a common and benign condition, there are no specific preventive measures that can be taken to avoid its development. The condition is thought to result from normal variations in fetal development, and its occurrence is not influenced by any specific actions or interventions.
Outlook / Prognosis
Stork bites and other forms of nevus simplex are harmless and add a unique cosmetic feature to your baby’s appearance. They do not need treatment and pose no threat to your child’s overall health.
It is normal for the color of your child’s stork bite to turn bright pink, red, or purple and become more noticeable when your child cries or gets too warm. If your child’s stork bite grows in size, shape, or turns a different color than normal, visit your child’s healthcare provider for an examination.
Stork bites are generally a benign and self-limiting condition. Most will fade over time, and any residual marks are usually covered by hair or are not prominent enough to cause concern. Parents can be reassured that the presence of nevus simplex does not indicate any underlying health issues and that the condition will likely resolve without the need for medical intervention.
Duration
Stork bites are present at birth and may fade after your child turns one to two years old. The birthmark could last through childhood but will often be present when your child reaches adulthood.
For most children, the appearance of nevus simplex will diminish significantly within the first few years of life. However, some lesions, particularly stork bites, may persist into adulthood. These persistent lesions are typically covered by hair and do not pose any health risks. The duration and persistence of these birthmarks can vary, but they generally do not cause any long-term problems.
When to Seek Medical Advice
If you notice your child’s stork bite changes color to something different than pink, red, or purple, if your child’s birthmark grows in size, or if the skin around the birthmark
