Prurigo pigmentosa: an underdiagnosed disease in patients of Iranian descent?
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.


CONCLUSIONS
The small number of patients in this study is a limitation.


CONCLUSIONS
We suspect that PP may have a proclivity in the Iranian population.
