Nevus Sebaceus


Simple surgical excision is preferable if the decision is made to remove the lesion. It is not necessary, however, to extirpate every nevus sebaceus, as was advocated in times past when trichoblastomas that often develop in them were thought to be basal-cell carcinomas. In fact, however, a malignant neoplasm may arise in the course of a nevus sebaceus, just as a melanoma may originate in conjunction with a melanocytic nevus. Not all nevi need to be excised, and so it is, too, for nevus sebaceus.
