Dermoscopic features of ocular and extraocular sebaceous carcinomas

Abstract

Sebaceous carcinomas are rare but potentially fatal malignant adenocarcinomas with varying degrees of sebaceous differentiation. Several dermoscopic findings of extraocular sebaceous carcinomas have been reported; however, there are no previous reports of ocular sebaceous carcinomas detected using dermoscopy. We present a case of ocular sebaceous carcinomas showing specific findings from dermoscopy, and describe the common dermoscopic characteristics. In our cases and a review of cases in the literature, we noted that polymorphous vessels and yellowish areas were observed in all eight cases. Thus, we consider that dermoscopic findings of polymorphous vessels with yellow backgrounds suggest sebaceous carcinoma.
