Abstract

PURPOSE: Nevus sebaceous is a distinctive growth commonly found on the scalp, forehead and retroauricular region. Nevus sebaceous has age-related changes in morphologic and histologic appearance. Secondary neoplasm including basal cell carcinoma is found in 20% of the nevus sebaceous which were not treated properly. So, we report a case of basal cell carcinoma that is arising in nevus sebaceous but has no malignant appearance.
METHODS
A 38 year-old female patient wanted to excise the lesion on scalp. It looked like typical nevus sebaceous because we didn't find any malignant appearances. We excised the lesion including minimal normal tissue.
RESULTS
After the excision of the lesion, pathologist reported the nevus sebaceous with multifocal basal cell carcinoma.
CONCLUSION
Many patients want to excise the nevus sebaceous that stands out to other people. But they don't know the potency of malignant changes. So, plastic surgeons have to notify the potency and make plan for proper treatment.
