What is herpetic stomatitis commonly known as, and what virus is it caused by?
Where does HSV1 survive in dormant state?
In the nerves ganglion corresponding to site of infection (on face usually trigeminal ganglia)
What is Moniliasis?
Another name for Candidiasis or "thrush"
Is candidiasis easily scraped off?
What type of conditions predispose someone to candidiasis?
immunocompromised (e.g. HIV)
What is a mucocele?
Obstruction of oral mucosa mucous gland resulting in a cystic dilation of duct filled with mucin. Due to trauma or inflammation. Not neoplastic.
T/F- Leukoplakia and erythroplasia are potentially premalignant lesions?
Can leukoplakia be removed by simple scraping of the lesion?
What causes leukoplakia?
irritation and inflammation
T/F- leukoplakia is usually malignant?
False, only 1-15% are pre-cancerous
Looking at leukoplakia under a microscope, what two characteristics will you see?
2. mucosal epithelial hyperplasia
Is erythroplasia more or less likely to progress into cancer than leukoplakia?
T/F- in general prognosis worsens corresponding to the further back in the mouth/phayrnx the lesion is?
What is the most common malignant tumor of the oral region?
squamous cell carcinoma
What virus is often responsible for causing rhinitis?
Repeated episodes of allergic rhinitis can lead to what condition of the nose?
thick mucosa and nasal polyps
Name 2 causes of necrotizing granulomatous sinusitis
1. wegeners granulomatosis
2. Mucor (zygomycetes) fungal infection

T/F- mucor (zygomycetes infection is rarely fatal
False, fatal infections often occur due to extension of fungal elements into the brain. This is a medical emergency.

-patients with GI reflux
-Treat with medical or surgical therapy
Benign, NEOPLASTIC, squmous cell papillomas of the larynx are treated with surgical therapy. What virus can cause multiple recurrences of this, particularly in juveniles?
