Abstract:
Prurigo pigmentosa - a rare dermatosis described first by Nagashima in 1971 - presents as intensely pruritic papules arranged in a reticular pattern and distributed symmetrically on the back of young women. Individual lesions involute within weeks, leaving net-like pigmentation, but recurrences are the rule. According to the recent report of Ackerman et al., prurigo pigmentosa shows discernable characteristic histopathologic stages successively in its natural course. We report two cases of prurigo pigmentosa with clinico-histopathologic analysis - one, occurred in 24-year old man who recovered spontaneously after 7 months of morbidity and the other, occurred in 23-year old woman who responded dramatically to dapsone.
