Sebaceous nevus is a congenital hamartoma commonly associated with the development of secondary neoplasms. It has a predilection for the scalp and less commonly manifests on the face, the neck, and the trunk. The lesions presented in our cases are from the trunk of a 19-year old man, the forehead of a 25-year old man, the scalp of a 22-year old woman and from the face of a 45-year old man. Two of four cases were associated with secondary neoplasms, syringoma and basal cell carcinoma. Dermoscopy of nevus sebaceous demonstrated yellowish-brown globular structures, presenting either singly or in clusters and pink-brown-grey papillary appearance. The specific dermoscopic findings in our case associated with basal cell carcinoma were fine arborizing and serpiginous vessels at the periphery of the lesion and exophytic grey papillary structures. Dermoscopy can be a useful diagnostic tool for diagnosing and monitoring nevus sebaceous in order to detect different tumors associated with nevus sebaceous and avoid unnecessary excisions and scars in aesthetically sensitive locations.
