Linear Nevus Sebaceous Syndrome: Clinical Presentation and Management Considerations

A relatively rare neurocutaneous condition known as linear nevus sebaceous syndrome (LNSS) is marked by a variety of symptoms as well as the unusual characteristics of developing mosaic RASopathies of phacomatoses. Mental retardation, seizures, and midline facial linear nevus sebaceous were the usual diagnostic triad. A hallmark of LNSS is the papillomatous growth of the epidermis, also known as nevus sebaceous. In this case report, we presented a case of a 13-year-old male with LNSS with a vascular conjunctival lesion and a coloboma of the optic disc.
