Porokeratosis is an autosomal dominantly transmitted disorder of keratinization predominantly affecting trunk and extremities. Many clinical variants have been described having a common histopathological feature of coronoid lamella-porokeratosis of Mibelli, superficial disseminate, disseminated superficial actinic porokeratosis, linear porokeratosis and punctuate palmoplantar porokeratosis. We present a case of 16-year-old female who had focal lesions of porokeratosis aggravated by sun exposure, over alae of nose confirmed by histopathology. The previous reports show quite a number of cases of isolated lesions of the disease on nose and perinasal area. This article highlights the actinic nature of focal facial porokeratosis.
