Macular posterior pigmentary incontinence: its relation to macular amyloidosis and notalgia paresthetica

Abstract

Patients with clinical features of dorsal macular amyloidosis but without subepidermal amyloid deposits were followed for 2-11 years. The clinical appearance was fairly stable during this period of time, with little tendency of healing. Only 2 of the patients developed typical macular amyloidosis during the follow-up. It is concluded that a condition strongly resembling macular amyloidosis but without amyloid is an entity, and the designation "macular posterior pigmentary incontinence" is proposed. The relationship between macular posterior pigmentary incontinence and the two conditions macular amyloidosis and notalgia paresthetica is discussed.
