A Case of Basal Cell Epithelioma Arising in a Nevus Sebaceus during Childhood

The potential for sebaceous nevi to evolve into secondary benign or malignant EuIror is well recognized. In general, malignant transformation does not occur until postpubertal life. We experienced a case of basal cell epithelioma arising in a nevus sebaceous on a 12-year-old boy´s parietal scalp. We recommended that surgical excision should be undertaken as early as possible to detect the malignant transformation of nevus sebaceous.
