Darier disease (DD) is an autosomal dominant genodermatosis characterized by multiple keratotic and crusted papules over seborrheic areas, along with a variable involvement of oral mucosa, palmoplantar region, and nails. Segmental subtypes (type 1 and 2) are uncommon clinically limited forms of DD that usually present at middle age with few cutaneous lesions following Blaschko´s lines. We report a case of extensive multi segmental DD type 1 that developed in an elderly man, an unusual clinical onset of DD that dermatologists should bear in mind.
