Abstract:
The varicella-zoster virus (VZV), a member of the Herpesviridae family (HHV-3), is the pathogen responsible for causing herpes zoster, the skin eruption known as shingles. This report describes a rare presentation of herpes zoster involving cutaneous vasculitis in the unilateral upper extremity in an immunocompetent patient. Histologic evaluation confirmed a diagnosis of leukocytoclastic vasculitis and yielded a positive VZV immunoperoxidase stain. An approach to histologic evaluation of this case is discussed.

Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
