Unusual Presentation of Facial Porokeratosis: Dermoscopic Findings and Evolution

The term porokeratosis refers to a group of genetic dermatoses characterized by the histological presence of cornoid lamellae. Here, we report the case of a 12-year-old female with an unusual facial form of the disease that was restricted to the lower eyelid. We describe characteristic dermoscopic findings of this lesion in two distinct stages of its evolution. In addition, we highlight the diagnostic value of dermoscopy for porokeratosis.
