For example, epilepsy may be treated by anti-seizure medications and certain skeletal and ocular malformations may also be treated surgically. In the medical literature, several cases have been reported where neurosurgery has been used to treat individuals with nevus sebaceus syndrome and epilepsy.

Some individuals may have a benign, yellowish-white, fatty tumor on the outer portion of the eyeball (epibulbarlipodermoid). A sebaceous nevus on the face can potentially involve structures in the eye including the eyelids and the thin, clear membrane that covers the outer surface of the eye (conjunctiva).

SN is commonly found on the scalp, temple, or preauricular region and is sometimes diagnosed at birth. Histologic analysis in children reveals epidermal hyperplasia and hypoplastic hair follicles and sebaceous glands. At puberty the sebaceous glands mature, and progression of the epithelial hyperplasia occurs. Progression to basal cell carcinoma (BCC) has been reported in up to 6% to 22% of adults.29

  2. Surgery may be performed to improve cosmetic appearance of individuals with nevus sebaceus syndrome. In the past, surgery was recommended because of the risk of malignancy. However, now that the risk of malignancy is much less than previously believed, this view is no longer advocated, especially if surgery will be disfiguring. In addition, the surgical excision of a lesion may not always be possible due to the specific location of the nevus.

Linear nevus sebaceous syndrome (LNSS), also known as epidermal nevus syndrome (ENS) or Schimmelpenning–Feuerstein–Mims syndrome, is a rare, highly variable congenital sporadic disorder that can feature, besides papillomatous epidermal hyperplasia and excess sebaceous glands, brain and eye abnormalities, focal or generalized skeletal disease and, in rare cases, hypophosphatemia leading to the development of rickets (Hoffman et al., 2005; Heike et al., 2005). Two recent reports have described increased FGF-23 concentrations in two patients, implying that this phosphaturic hormone contributes to renal phosphate wasting. While the skin lesions appeared to be the source of FGF-23 in one patient (Hoffman et al., 2005), the bone lesions were thought to secret this hormone in the other patient (Heike et al., 2005).Warnke PH, Russo PA, Schimmelpenning GW, et al.

Keratinocytic epidermal nevus (KEN) syndrome is a form of epidermal nevus syndrome involving a keratinocytic epidermal nevus (characterized by epidermal hyperplasia without enlarged and malformed sebaceous glands). The associated extracutaneous manifestations are similar to those seen in nevus sebaceus syndrome. The exact same postzygotic mutations of the KRAS and HRAS genes have been identified in KEN. KEN has also been associated with mutations in FGF3 and keratins 1 and 10 (causing epidermolytic KEN).

Updates regarding government operating status and resumption of normal operations can be found at USA.gov Hormonal changes at the time of puberty can cause a nevus sebaceous to grow larger and develop a wart-like appearance. A lesion typically has an orange, brown, or yellow tint. If the condition is left untreated, there is very small risk of the lesion becoming malignant. A hard, rough tumor can develop and potentially grow very large on the head. It is unlikely for the cancer to spread quickly to other areas of skin or elsewhere in the body, however.

In addition, HRAS and KRAS mutations have been found in isolated sebaceous nevus (in the absence of associated extracutaneous abnormalities). More research is necessary to further explore the relationship of ras mutations and the complex phenotype seen in some affected patients. Essentially, nevus sebaceous is a hairless skin lesion that is present from birth. The color is somewhat orange or yellow and the lesion may be slightly raised or irregular

Familial cases have been reported. [1, 2, 3] Mutations in pluripotential cells during embryogenesis may generate varying lines of differentiation included in organoid nevi. Nevus sebaceus appears to respond to hormonal influences, as the lesion can be raised at birth, become flattened in childhood, and become raised again during puberty. Although nevus sebaceus is known to develop various types of secondary neoplasms, it rarely causes carcinoma and only 14 cases of secondary sebaceous carcinoma have.. Nevus sebaceus occurs with equal frequency in males and females of all races. Of newborns, 0.3% are affected by nevus sebaceus.

On hair-bearing areas, the partial or complete lack of terminal hairs within the lesion makes it particularly conspicuous. The tawny color is a gross clue to the presence of sebaceous differentiation. As with the normal sebaceous glands, the abnormal glands of nevus sebaceus are under androgenic control; thus the lesions often become clinically more conspicuous at puberty, with development of a mammillated or pebbled surface and more intense orange hue; lesions removed in the years before “sebarche” may show relatively small sebaceous glands.

It may be nodular at birth and again after puberty, flattening during childhood. A variety of neoplasms, both benign and malignant, including basal cell carcinoma, develop in up to 15% of patients with sebaceous nevi. Development of neoplasms rarely occurs before puberty.Nevus sebaceous most often occurs as isolated finding and usually is not associated with any abnormalities in other organs. However, when it occurs with additional extra-cutaneous symptoms, the term, nevus sebaceus syndrome, is appropriate.

Fearfield LA, Bunker CB. Familial naevus sebaceous of Jadassohn. Br J Dermatol. 1998 Dec. 139(6):1119-20. [Medline]. Nevus sebaceus is the most common type of organoid epidermal nevus (which broadly encompasses abnormally formed adnexal skin elements such as hair follicles and glands within the skin). Epidermal nevi are usually present at birth (congenital), although they might not be identified until later during childhood or after puberty. Affected individuals may also have abnormalities affecting the brain such as seizures or intellectual impairment, the eyes such as clouding (opacity) of the cornea or partial absence of tissue of the iris or retina (coloboma), and the skeleton such as spinal malformations, craniofacial defects, and deformities of the arms and legs. Nevus sebaceus syndrome occurs randomly for no apparent reason (sporadically) during the formation and development of the embryo (embryogenesis), due to a mutation of a gene (ras) that occurs after fertilization (postzygotic mutation) and is present in only some of the cells of the body (mosaic pattern).

In most cases, lesions are benign and do not cause health problems, though there is a very small chance that a nevus can become cancerous late in life. Patches are typically noticed at birth or in early childhood and tend to be soft, smooth, and more orange or yellow than surrounding skin. By puberty, they may become bumpy or rough to the touch. Treatment in the form of excision surgery is only needed if a nevus sebaceous turns malignant or becomes a major aesthetic concern for a patient.

If treatment is chosen, surgical excision would be the treatment of choice; however, the timing of the surgery is controversial.Additional therapies that may be used to treat individuals with nevus sebaceus syndrome include remedial education, physical therapy and occupational therapy all of which should be individualized. Genetic counseling may be of benefit for affected individuals and their families.

Immature adipose tissue and extramedullary hematopoiesis have been reported.1595 Lesions with meningothelial and muscular components are usually classified as rudimentary meningoceles or meningothelial hamartomas (see p. 881).1596 A mild chronic inflammatory cell infiltrate of lymphocytes and plasma cells is often present. Merkel cells are increased in those cases with follicular germ structures or with a superimposed trichoblastoma.1597David F Butler, MD Former Section Chief of Dermatology, Central Texas Veterans Healthcare System; Professor of Dermatology, Texas A&M University College of Medicine; Founding Chair, Department of Dermatology, Scott and White Clinic David F Butler, MD is a member of the following medical societies: Alpha Omega Alpha, American Academy of Dermatology, American Society for MOHS Surgery, Association of Military Dermatologists, Phi Beta KappaDisclosure: Nothing to disclose.

In nevus sebaceus, postzygotic somatic mutations may result in various clinical expressions of mosaicism. Mutations in pluripotential cells may give rise to hamartomas with multiple cell lines.Neurological abnormalities often occur in individuals with nevus sebaceus syndrome including seizures, delays in attaining developmental milestones (developmental delays), intellectual impairment, damage to certain cranial nerves and abnormalities affecting certain structures of the brain. Such abnormalities include one side of the brain being larger than the other (hemimegalencephaly), malformation (dysplasia) of the certain brain vessels, absence (agenesis) of the bundle of nerves that connects the two cerebral hemispheres (corpus callosum), and defects of the folds of the brain including a smooth brain that lacks the distinctive folds (agyria), abnormally small folds (microgyria) and abnormally thickened folds (pachygyria).

Our Global Patient Services team is here to help international and out-of-area families every step of the way. Nevus sebaceous is a congenital hamartomatous skin lesion that is commonly associated with other abnormalities and is most frequently located on the face and head Most patients with small, noncancerous lesions do not need aggressive treatment. Patches on the scalp can usually be concealed with a hat or by parting the hair a certain way. If a nevus sebaceous is malignant or causes appearance concerns, it can be cut out during a fairly simple outpatient surgical procedure. Photodynamic therapy, which involves eroding a lesion with a combination of acid and laser light, is a new and promising nonsurgical option for some patients.

Small epidermal nevi do not require treatment. Nevus sebaceous carries a small risk of malignant degeneration. It may be excised at any time, depending on the size of the lesion, the benefits of surgical intervention versus the risks of anesthesia, and the preference of the patient and family but rarely becomes symptomatic or much of an issue until after puberty. Recent studies suggest that the risk of basal cell carcinoma, the most common malignancy to arise in nevus sebaceous, is closer to 1%, much lower than was reported in the past (Cribier et al., 2000).Copyright ©2020 NORD - National Organization for Rare Disorders, Inc.

Another rare association with LNSS is hypophosphatemic rickets, which usually presents within the first years of life, often as skeletal pain and insufficiency fractures.190 The primary cause of LNSS is currently unknown, but a report described elevated serum FGF-23 in a patient with simultaneous therapy-resistant hypophosphatemic rickets.191 Treatment with octreotide and excision of the nevus were followed by normalization of serum FGF-23 and regression of symptoms, implying a role of FGF-23 in the development of hypophosphatemic rickets in this disorder.191Daniel Mark Siegel, MD, MS Clinical Professor of Dermatology, Department of Dermatology, State University of New York Downstate Medical Center Daniel Mark Siegel, MD, MS is a member of the following medical societies: American Academy of Dermatology, American College of Mohs Surgery, American Association for Physician Leadership, American Society for Dermatologic Surgery, American Society for MOHS Surgery, International Society for Dermatologic SurgeryDisclosure: Nothing to disclose.
