Abstract:
Disseminated superficial porokeratosis (DSP) is an autosomal dominant specific disorder of keratinization. Clinically, the lesions show a sharply demarcated and hyperkeratotic plaque with central atrophy, with a predilection for the extensor surface of the extremities. Unusual cases of DSP accompanied by severe pruritus have been reported as "eruptive pruritic papular porokeratosis" or "inflammatory DSP." Histopathologically, inflammatory DSP is characterized by the presence of cornoid lamella with a dense infiltration of lymphocytes in the perivascular area of the upper dermis. Here we report a case of inflammatory DSP in an 80-year-old man with choledocholithiasis.
