NEVUS SEBACEOUS, SYSTEMATIZED

By Gary M. White, MD

systematized nevus sebaceous


The systematized nevus sebaceous (SNS) is a very large nevus sebaceous that may be associated with various systemic abnormalities. It often follows Blaschko's lines.

Workup

The patient should be evaluated for abnormalities of the CNS, skeletal system, eyes. Appropriate studies beyond a good HP include skeletal survey, head CT or MRI, u.a., liver and renal studies, and calcium and phosphate.

Treatment

The patient should be referred to a plastic surgeon for consideration of cosmetic repair. For any portions that cannot be excised, long term observation for development of BCCs and rarely other neoplasms is indicated.
