Prurigo Pigmentosa Caused by Sweating


Prurigo pigmentosa is a peculiar pruritic pigmented dermatosis characterized by the sudden appearance of reddish papules accompanied by severe pruritus. The etiology still remains unknown but environmental factors may play a role, in which physical trauma or friction from wet clothing induces the skin lesions. It has a seasonal preference for spring to summer when there is increased sweating. We report a case of prurigo pigmentosa which may be triggered by sweating and cured with minocycline.
