There are five different types in the group of porokeratosis which is one of the keratinization disorders: disseminated superficial actinic porokeratosis, punctate porokeratosis, porokeratosis palmaris et plantaris disseminata, linear porokeratosis and porokeratosis of Mibelli (PM). PM is classic and the most common type that can be seen anywhere on the body skin. Disseminated superficial actinic porokeratosis is another type of porokeratosis which is characterized by widespread, bilateral and symmetric eruptions seen on sun-exposed areas. Although they are asemptomatic, treatment is recommended because of the possibility of developing skin malignancies. However, none of the current treatment approaches is fully effective. Here, we report two male patients diagnosed with PM and disseminated superficial actinic porokeratosis who demonstrated improvement with acitretin treatment.
