  It may appear as a yellow or tan waxy patch of alopecia at birth. During puberty the lesion becomes raised, thick, and verrucous. It is usually treated with local excision. [medical-dictionary.thefreedictionary.com]

  There is a report on initial presentation as neonatal alopecia [ 5 ]. [omicsonline.org]

To the authors' knowledge, this report represents the largest surgical series and suggests a reliable approach to the treatment of the cutaneous manifestations of this syndrome. [ncbi.nlm.nih.gov]

Treatment Options The surgical option of choice is excision. Physical treatment with photodynamic therapy (PDT), CO2 laser, and dermabrasion has been reported, but these are not preferred treatment modalities. [dermatologyadvisor.com]

Etiology LNSS is a sporadic disease. It is hypothesized that the epidermal nevus syndromes are the result of genetic mosaicism involving a dominant gene. [orpha.net]

Etiology Schimmelpenning syndrome is caused by sporadic (not inherited) somatic mutations in a cell belonging to the ectodermal germline in the embryo. This is a post-zygotic mutation, and usually affects the HRAS, KRAS and NRAS genes. [news-medical.net]

Etiology Pathophysiology The cause of this condition is unknown, but it is possibly linked to postzygotic somatic gene mutation involving PTCH gene. Maternal human papillomavirus (HPV) may be a risk factor. [dermatologyadvisor.com]

Other investigations for the etiology of hemiplegia (hematological, immunological and infectious) were normal. [indianpediatrics.net]

Summary Epidemiology The incidence of sebaceous nevi at birth is estimated at 1 in 1000 but the prevalence of these lesions in association with other anomalies, as in the case of LNSS, varies between case reports to around 1:10,000. [orpha.net]

EPIDEMIOLOGY Epidermal nevi occur in approximately 1 to 3 per 1000 live births; males and females tend to be equally affected [ 2 ]. [uptodate.com]

Image from the Dermatology Atlas Epidemiology Estimated prevalence is 0.3% of all newborns worldwide, with an equal sex distribution [ 2 ]. [patient.info]

Epidemiology Nevus sebaceous occurs in approximately 0.3% of all newborn infants [1]. Both sexes are equally affected [5]. There is no racial and or ethnic predominance [2]. [austinpublishinggroup.com]

Etiology Pathophysiology The cause of this condition is unknown, but it is possibly linked to postzygotic somatic gene mutation involving PTCH gene. Maternal human papillomavirus (HPV) may be a risk factor. [dermatologyadvisor.com]

OP onset is often prevented using a tetravalent human papillomavirus (HPV) vaccine. However, since LEN is not an infectious pathology, there is no preventive treatment ever described [ 6 ]. [hindawi.com]

Current medical research has not established a way of preventing a Nevus Sebaceous. [dovemed.com]

Previous studies reported as much as a 10% risk of developing BCCs in nevus sebaceous, leading to the recommendation of excision to prevent “skin cancer”. However, it is now thought that less than 1% of lesions actually develop BCCs. [healio.com]

For those who do choose to reduce the appearance of their nevus sebaceous for cosmetic purposes or to prevent malignant growths, laser treatment can be an effective option. [healthline.com]
