Nevus sebaceus - Hair and Scalp
Removal is recommended before adulthood due to the small risk of a malignancy developing within the lesion during adulthood. Traditionally, the risk of malignant transformation within lesions was approximated at 5%-15%, although this is now considered an overestimation. Other benign adnexal neoplasms, including trichoblastoma and syringocystadenoma papilliferum, occur more frequently. In rare cases, basal cell, squamous cell, sebaceous, or apocrine carcinomas can develop within a nevus sebaceous. For those who decline surgical excision, periodic skin examinations are advised.
In cases with a large plaque or multiple plaques, a diagnosis of nevus sebaceus syndrome may be considered. This condition may manifest with neurologic, ocular, and musculoskeletal abnormalities.
