Study Notes
Oral Sores and Herpetic Infections
- Sores primarily affect the lips and oral mucosa of medical and dental personnel, often following minor injuries.
- Herpes Simplex Virus (HSV) types 1 and 2 are implicated as potential causes of these lesions.
- Lesions may appear as confluent, pustular, or hemorrhagic blisters, often complicated by bacterial superinfection.
- Eczema herpeticum can lead to viral dissemination into internal viscera, posing life-threatening risks.
Chicken Pox and Ramsay Hunt Syndrome
- Chicken pox establishes latent infections within sensory ganglia.
- The virus can infect neurons, leading to potential reactivation years later, resulting in shingles.
- Ramsay Hunt syndrome may involve the geniculate nucleus, leading to facial paralysis in affected patients.
Verruca Vulgaris (Common Warts)
- Known as common warts, typically occur on the dorsal aspect of fingers and hands.
- Associated with HPV types 2, 4, and 7, these lesions are painless, pruritic, and circumscribed papules (1-10 mm) with hyperkeratotic surfaces.
- Generally self-limited, warts may persist for several months or up to years and are notorious for autoinoculation, especially through the Koebner phenomenon.
HPV and Oncogenic Risks
- Low-risk oncogenic HPVs (types 6 and 11) are associated with condyloma acuminata.
- High-risk oncogenic HPVs (types 16, 18, 31, 33, 35) are linked to anogenital squamous cell carcinoma, with HPV-16 being the most frequent cause.
- Condyloma acuminata appears as soft, tan, cauliflower-like masses, commonly resulting from high-risk HPV infections.
Koebner Phenomenon
- The phenomenon results in the formation of new warts at sites of trauma, especially if the lesions have been scratched.
- It illustrates how dermatological conditions can manifest in response to skin injury or inflammation.
Cowdry Type A Inclusion Bodies
- Typically encountered in children, indicative of herpetic infections.
- Primarily caused by Herpes Simplex Virus (HSV) type 1.
- Microscopic findings include the presence of Cowdry Type A inclusion bodies in infected tissues.
Vesicular Eruptions
- HSV type 1 presents with vesicular eruptions and cervical lymphadenopathy, which may include swollen and tender lymph nodes.
- HSV type 2 primarily affects the genital area, presenting with vesicles on mucous membranes and external genitalia.
- Vesicles from HSV type 2 rapidly progress to superficial ulcerations upon bursting.
Histopathology
- The earliest change in the skin involves nuclear swelling of keratinocytes at the basal layer, eventually affecting the entire epidermis.
- Histological examination reveals multinucleated giant cells (polykaryons), a hallmark of HSV infections.
Special Cutaneous Forms
- HSV can lead to unique skin manifestations, characterized by distinct lesions and ulcerations at various body sites.
- Early skin changes serve as indicators for diagnosing HSV and require specific histopathological evaluation for confirmation.
