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