    Insights

    This case report details Herpes zoster affecting only the mandibular nerve in an elderly man. The rare distribution suggests a specific latent virus site within the trigeminal nerve

    Area of Science:

    • Neurology
    • Infectious Diseases
    • Ophthalmology

    Background:

    • Herpes zoster, commonly known as shingles, is caused by the varicella-zoster virus (VZV).
    • VZV reactivation typically manifests with a characteristic unilateral, dermatomal rash.
    • Ophthalmic involvement is a known complication, but isolated mandibular nerve zoster is infrequent.

    Observation:

    • A rare case of Herpes zoster exclusively affecting the mandibular nerve is presented.
    • The patient was an 80-year-old male.
    • The clinical presentation involved lesions limited to the distribution of the mandibular nerve.

    Findings:

    • Herpes zoster infection limited to the mandibular division of the trigeminal nerve is uncommon.
    • The study proposes a unique latent site of the varicella-zoster virus within specific neurons of the gasserian ganglion.
    • This specific neuronal localization is hypothesized to explain the isolated mandibular nerve involvement.

    Implications:

    • This case highlights the diverse clinical presentations of Herpes zoster.
    • Understanding specific viral latency sites may aid in predicting and managing atypical VZV reactivation patterns.
    • Further research into neuronal tropism of VZV could refine diagnostic and therapeutic strategies for trigeminal nerve involvement.

    Herpes01:28

    Herpes

    Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
    Chickenpox01:20

    Chickenpox

    Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
    Poliomyelitis01:17

    Poliomyelitis

    Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
    Rabies01:28

    Rabies

    Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
    Genital Herpes01:23

    Genital Herpes

    Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
