Abstract

Prurigo pigmentosa (PP) was originally described 45 years ago, yet because of its variable histopathological manifestations it remains an under-recognized inflammatory dermatosis clinically characterized by recurrent pruritic, erythematous macules, urticarial papules and papulovesicles that eventuate in symmetric reticulated pigmentation.1 Although the majority of cases have been reported in women of Asian descent, it also has been described in various ethnicities worldwide. Of the approximately 400 reported cases of PP, fewer than 10 have been reported from the United States.
