RESUMEN
Inflammatory disseminated superficial porokeratosis is an unusual pruritic variant of disseminated superficial porokeratosis, and this was first described by Kanzaki in 1992 as eruptive pruritic papular porokeratosis. Since the first report, 8 cases of inflammatory disseminated superficial porokeratosis have been reported in English language dermatologic literature and only one case has been reported in the Korean dermatologic literature. The condition is clinically characterized by an acute pruritic exacerbation of disseminated superficial porokeratosis, which had been asymptomatic for several years. Usually the skin lesions show improvement after several months, leaving brownish atrophic lesions. Histopathologic examination reveals the cornoid lamella with an infiltration of eosinophils and lymphocytes in the upper dermis. Herein, we report on an 81-year-old Korean man with inflammatory disseminated superficial porokeratosis, and this was clinically and histopathologically diagnosed.
