Multidermatomal Herpes Zoster of the trigeminal nerve in an immunocompetent patient: a case report

Abstract

Herpes Zoster is a neurocutaneous viral infection caused by the reactivation of the Varicella Zoster Virus in the dorsal root ganglion. It is characterized as vesicular rash along a unilateral dermatome, usually associated with pain or paresthesia of the involved area. Multidermatomal involvement is rare in immunocompetent patients. We report an unusual case of Herpes Zoster involving the maxillary(V2) and mandibular(V3) branches of the trigeminal nerve in a healthy immunocompetent lady. Keywords: herpes zoster, neurocutaneous viral infection, trigeminal nerve
