Abstract
- Disseminated superficial actinic porokeratosis (DSAP) is a rare keratinization disorder. It is histopathologically characterized by the presence of coronoid lamellae and clinically by lesions showing central atrophy with elevated borders. Squamous cell carcinoma originating in the classical Mibelli subtype of porokeratosis is well-documented; however, few reports have described squamous cell carcinoma in DSAP lesions. We report the case of a 76-year-old woman with DSAP who developed Bowen's disease, actinic keratosis, and keratoacanthoma on her face.
