PP is characterized by verrucous plaques, often resembling psoriasis plaques, that affect the buttocks, most commonly the gluteal cleft, and can also involve the extremities, most commonly the lower legs and feet. Due to its characteristic verrucous appearance, designations such as verrucous or hyperkeratotic porokeratosis are occasionally used. Besides its predilection for specific locations, PP also has a significant predilection for men …
