Eruptive pruritic papular porokeratosis.
Three cases of an unusual variant of porokeratosis (Mibelli) were described. Patients with disseminated superficial porokeratosis for some years suddenly developed intensively pruritic erythematous papules. Skin biopsies revealed that these papules contained cornoid lamellae on their tops. Pruritic papules subsided in several months, leaving slightly hyperkeratotic brown annular lesions which were shown to contain typical cornoid lamellae histopathologically. This type of porokeratosis has not been reported in the literature.
