Herpes Zoster with Post Herpetic Neuralgia Involving the Right Maxillary Branch of Trigeminal Nerve: A Case Report and Review of Literature.

Herpes Zoster (HZ) is an acute, self-limiting, neuro cutaneous viral infection caused by the reactivation of the Varicella Zoster Virus (VZV) that remains latent in the dorsal root ganglion. About 50% of occurrence is seen in older age groups and immunocompromised patients. Less than 5% occur in children. HZ is characterized by the unilateral pain, burning and tingling sensation followed by the vesicular eruptions limited to the single dermatome that are innervated by the single cranial ganglion, sometimes it leads to Post Herpetic Neuralgia (PHN). We report a case of a HZ in a 22-year-old young female patient involving the right maxillary branch of the trigeminal nerve along with PHN.
