AbstractLocalized neuropathic pain (LNP) is a type of neuropathic pain characterized by consistent and circumscribed area(s) of maximum pain, which are associated with negative or positive sensory signs and/or spontaneous symptoms typical of neuropathic pain. This description outlines the clinical features of a group of pathologies, in which a LNP can be diagnosed and for whom topical targeted treatment with 5% Lidocaine medicated plaster can be suggested. Indeed both American as well as European guidelines already suggest 5% Lidocaine medicated plaster as a first line treatment in post herpetic neuralgia and in general in the treatment of conditions such as diabetic painful polyneuropathy and post surgical pain where a LNP can be ascertain. In a daily practice of a Pain Unit however the usual case mix encompasses also other causes of LNP, most of them with a scanty pain control in spite of a ongoing polytherapy. Aims of this paper were to focus on 5% Lidocaine medicated plaster as a first line treatment in LNP and to add new insight on its possible use as add-on therapy reporting our data on a consecutive series of 42 patients affected by LNP under unsatisfactory polytherapy in which 5% Lidocaine medicated plaster was able to achieve a satisfactory pain control.
