Neuropathic pain, which is defined as pain caused by direct nerve lesions, may have different causes and a variety of clinical presentations. A correct management of chronic neuropathic pain requires a thorough understanding of the potential causes, the diagnosis and the pathophysiological mechanisms.

Methods. An extensive literature review was performed using Pubmed citations.
Results and conclusions. This article, which is based on extensive literature review, aims at providing a concise review of the current knowledge regarding aetiology, diagnosis and pathophysiology of neuropathic pain.
