In herpes zoster ophtalmicus the Varicella Zoster Virus reproduces and causes an inflammatory proccess of ophtalmic-trigeminal facial skin, and occassionally other divisions ot this nerve. It may be associated with orbitary complications (potentially leading to blindness), and oral, auditive and muscular alteraions if caudal branches are affected. Skin lesions present an histology of sterile vasculitis and granulomatous liponecrosis. As a result skin necrosis may appear, as well as alveolar necrosis, teeth loss and fistulae. Late arteritis of the temporal artery as a complication of herpes zoster is an extremely uncommon proccess, in which it is not possible to demonstrate viral particles. It is considered a consequence of the proximity extension of the granulomatous vsaculitis to the carotid system, not a direct viral invasion. We present to cases of this entity. One affecting the ophtalmic and maxillary divisions, causing orbitary disease and gingivitis. The other one was an inmunodepressed patient with acute retinal necrosis and aggressive intracraneal vasvulitis. Both presented scalp necrosis requiring surgery.
