NOTALGIA PARESTHETICA, POSTERIOR PIGMENTE D PRURITIC PATCH AND MACULAR AMYLOIDOSIS - 3 STAGES OF THE SAME DISEASE

We report on nine cases of notalgia paresthetica, a cutaneous conditio n 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 studi es have not clarified the pathogenesis of this disease. Several factor s might be involved in various cases, including increased cutaneous in nervation and neuropathy. The so-called posterior pigmented pruritic p atch and macular amyloidosis may be considered as progressive evolutio nal stages of notalgia paresthetica.
