ch 09 allergies and immunologic diseases Flashcards
- Unknown etiology but could be irritation, stress, GI disease, hormonal changes, URI, viral infection or topical hypersensitivity.
- Elevated painful fungiform papillae, often red, white or yellow in color.
- Resolve on their own but steroid, anesthetics and coating agents have been tried.
transient lingual papillitis
-One of the most common oral mucosal pathoses
-Prevalance - 5% to 66%
-Pathogenesis: various theories = different
things in different people
-primary immunodysregulation
-decrease of the mucosal barrier
-increase in antigenic exposure
recurrent aphthous stomatitis
the three clinical variations of recurrent aphthous stomatitis
- minor apthous ulcerations
- major aphthous ulcerations
- herpetiform aphthous ulcerations
Multisystem disorder
n Oral lesions first manifestation in 25% - 75% soft palate and oropharynx
n Oral involvement at some point 99% n Genital lesions 75%
n Ocular lesions 70% - 85%
n CNS involvement – 10% to 25%
Behcet’s syndrome
A multisystem granulomatous disorder of unknown etiology
n Blacks affected 10 – 17 times more frequently than whites.
n Bimodal age predilection: 25-25 & 45-65
n Commonly appears acutely
n Dyspnea, dry cough, chest pain, fever, malaise, fatigue, arthralgia, weight loss
n Lungs, lymph nodes, skin, eyes, and salivary glands
Sarcoidosis
noncaseating granulomas
sarcoid lesions
Idiopathic abnormal immune reaction to ? n Biopsy shows multinucelated giant cells and granuloma, so you have to rule out Sarcoid, Crohn’s disease, Fungus infection, Foreign body reaction
orofacial granulomatosis
Orofacial granulomatosis + facial paralysis + fissured tongue
Melkersson-Rosenthal syndrome
allergic mucosal reactions to systemic drugs
“stomatitis medicamentosa”
allergic contact stomatitis
-food, gum, topicals, acrylics etc
latex allergy:
allergic contact dermatitis
unique inflammatory skin disease that involves the circumoral area
perioral dermatitis
-tx: metronidazole
lichenoid contact stomatitis from dental resotorative materials
- amalgam
- similar to lichen planus
- Diffuse edematous swelling
- Subcutaneous and submucosal connective tissue
- GI or respiratory tract
- Mast cell degranulation leads to histamine release
- IgE-mediated hypersensitivity reactions n Foods, cosmetics, topicals, rubber dam
angioedema (angioneurotic edema; quincke’s disease)
