Abstract:
Prurigo pigmentosa is a chronic pruritic inflammatory dermaoss characterized by erythematous papules in a reticulated pattern that resolve leaving a reticulated, mottled hyperpigmentation. Most cases have been reported from Japan. Two cases of prurigo pigmentosa have been reported in Korean women. We experienced a casc of prurigo pigmentosa in a Korean man of 20 years of age. Histopathological findings of reddish papule showed exocytosis, sponsiosis, intraepidermal vesicles, hydropic degeneration of basal cells in the epidermis, and hyphohistiocytic infiltration in the upper dermis. Direct irnmunofluorescence was negetive. Therapy with dapsone, 50 mg given daily, resulted in a rerinable regression of the reddish papules. The daily dose of clapsone was reduced to 25mg; however, no new reddish, pruritic papules have appeared.
