Sebaceous Carcinoma Arising from Nevus Sebaceus / 대한피부과학회지

ABSTRACT

Nevus sebaceus is a hamartoma of both epithelial and non-epithelial components, which that undergoes age-related change. It commonly affects the head and neck, particularly the scalp. In 10-20% of nevus sebaceus cases, secondary benign or malignant neoplasms such as syringocystadenoma papilliferum, trichoblastoma or basal cell carcinoma occur between 40-80 years of age. In only rare instances does a sebaceous carcinoma develop within a nevus sebaceus. To our knowledge, only 3 cases of sebaceous carcinoma in nevus sebaceus have been reported in the Korean dermatologic literature. We present a case of a sebaceous carcinoma arising from nevus sebaceus in a 46-year-old Korean man.
