Nevus Sebaceus Associated with Trichilemmoma, Trichilemmal Carcinoma and Trichoblastoma / 대한피부과학회지

ABSTRACT

Nevus sebaceus is located on the scalp or the face as a single lesion and is already present at birth. In adulthood, various types of appendage tumor may develop secondarily within the lesion of the nevus sebaceus. A syringocystadenoma papilliferum is the most common secondary benign tumor that has been found in 8% to 19% of the lesion of nevus sebaceus. The malignant tumors arising from nevus sebaceus are basal cell carcinoma, squamous cell carcinoma, apocrine carcinoma and malignant eccrine poroma. The combination of a variety of tumor was found in the lesion of nevus sebaceus. We report a case of nevus sebaceus in a 66-year-old male associated with trichilemmoma, trichilemmal carcinoma and trichoblastoma.
