Prurigo pigmentosa: An underdiagnosed disease in patients of Iranian descent?

BackgroundPrurigo pigmentosa (PP) is a rare inflammatory disease of the skin typified by recurrent, pruritic erythematous macules and papules that resolve leaving behind netlike pigmentation.ObjectivePP is diagnosed most commonly in Japanese women. Preponderance of the disease in other ethnic populations has yet to be identified.MethodsWe conducted a clinicopathologic case study in 4 Iranian women.ResultsThe clinical diagnosis of PP was confirmed by typical histopathologic findings, elucidating the morphologic spectrum of the disease.LimitationsThe small number of patients in this study is a limitation.ConclusionWe suspect that PP may have a proclivity in the Iranian population.
