Multiple Adnexal Neoplasms Arising from Nevus Sebaceous / 대한피부과학회지

ABSTRACT

Nevus sebaceous is a tumor of primary epithelial germ cells that is generally first noticed at birth. Clinically, there is a yellowish waxy plaque with overlying alopecia on the scalp. Less commonly, it can be seen on the face, trunk, and extremities. Syringocystadenoma papilliferum is the most common benign growth from nevus sebaceous, whereas basal cell carcinoma is the most frequent malignancy. The proportion of the malignant tumors occurring on nevus sebaceous is highly variable according to the published series, and there are controversies on the nature of these neoplasms. We experienced a rare case of nevus sebaceous, superimposed of 5 multiple type tumors at the comparatively young age syringocystadenoma papilliferum, basal cell carcinoma, nevocellular nevus, sebaceous adenoma, and syringoma. We treated the patient with total excision, and followed up during 1 year. The patient showed no recurrence.
