Abstract:
Prurigo pigmentosa is a chronic inflammatory dermatosis characterized by reticulated erythematous papules, hyperpigmentation with severe pruritus and usually occurs in young femals around their twenties. Most cases have been reported from Japan, but only twelve cases have been reported in Korea. Histopathologic findings of erythematous papules shows spongiosis, exocytosis, liquefaction degeneration of the basal cell, perivascular lymphohistiocytic infiltration in the dermis and finally dermal fibrosis and deposit of dermal melanophages in hyperpigmented lesions. We report three cases of prurigo pigmentosa which showed various histopathologic features of early, fully-developed and late stage, respectively.
