title: [Notalgia paresthetica, "posterior pigmented pruritic patch" and macular amyloidosis. Three stages of a disease].
abstract: We report on nine cases of notalgia paresthetica, a cutaneous condition that has rarely been described in the dermatological literature and is characterized by localized pruritus, burning and hyperesthesia and/or paresthesia on the back. Histological and immunohistochemical studies have not clarified the pathogenesis of this disease. Several factors might be involved in various cases, including increased cutaneous innervation and neuropathy. The so-called posterior pigmented pruritic patch and macular amyloidosis may be considered as progressive evolutional stages of notalgia paresthetica.
