Two Cases of Dieting-associated Prurigo Pigmentosa / 대한피부과학회지

ABSTRACT

Prurigo pigmentosa is a rare inflammatory dermatosis of unknown etiology characterized by recurrent, pruritic, erythematous papules with gross reticulate hyperpigmentation. The cause of prurigo pigmentosa is unknown. Exogenous factors, fasting, dieting, ketosis, diabetes mellitus and pregnancy have been reported to be associated with prurigo pigmentosa. We now present two cases of prurigo pigmentosa associated with dieting. These findings suggest that the ketosis produced by dieting may well contribute to the pathogenesis of prurigo pigmentosa.
