Abstract
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.
