Prurigo pigmentosa is a rare skin disease of unknown etiology which is most common in Japan where nearly 200 cases have been reported. Only a few cases, instead, have been described in the Western countries. Prurigo pigmentosa is a recurrent pruritic dermatosis characterized by red papules continuously formed that eventually coalesce to form a characteristic reticulated mottled pattern. Later the reddish papules resolve leaving residual areas of non itching pigmentation. The lesions are usually asymmetrically found on the neck and the trunk, but there are reports of other localisations on the breasts, limbs, abdomen, antecubital fossa, lumbosacral region, face and forehead. The pathological finding is that of a lichenoid reaction in the dermis. The Authors describe two cases of prurigo pigmentosa in two female patients respectively 33 and 25 y.o. Oral dapsone led to a dramatic improvement in both the patients.
