Background:
Most clinicians easily diagnose typical clinical signs and symptoms of herpes zoster. However, in certain circumstances and in special populations, herpes zoster can present with rare manifestations and can cause potentially life-threatening complications. Clinicians must be aware of these presentations and be prepared to perform appropriate diagnostic studies. Clinical importance of herpes zoster arises from mainly its complications. Quick identification of these complications and proper early management are essential to decrease their severity and improve outcomes.
