Study Notes
Vesiculobullous and Ulcerative Lesions
- Oral ulcerative lesions can result from various causes, including trauma, infection, and systemic diseases.
- Recurrent aphthous stomatitis (RAS) is common, characterized by painful ulcerations in the mouth.
Recurrent Aphthous Stomatitis (RAS)
Minor Aphthous Ulcerations
- Most prevalent type (80% of RAS cases).
- Diameters range from 3 to 10 mm, typically manifesting as multiple lesions (1 to 5 per episode).
- Symptoms include burning, itching, and stinging prior to ulcer formation.
- Ulcers have a yellow-white membrane and an erythematous halo, healing without scarring within 7-14 days.
- Commonly occur on buccal and labial mucosa, with pain often disproportionate to ulcer size.
Major Aphthous Ulcerations
- Present in 10% of RAS patients, larger (1 to 3 cm) with longer healing periods (2-6 weeks).
- Can affect any oral surface, frequently involving labial mucosa and soft palate.
- May lead to scarring after healing and onset typically occurs post-puberty.
Herpetiform Aphthous Ulcerations
- Characterized by numerous small lesions (1 to 3 mm) that may coalesce into larger ulcers.
- May mimic primary herpes simplex virus lesions but show weak evidence of viral causes.
- Up to 100 small lesions can be present per episode, usually healing within 7-10 days.
- More common in females and may emerge in adulthood.
Diagnosis and Treatment of RAS
- Review medical history for systemic issues.
- Treatment options include dexamethasone solution as mouth rinse, topical corticosteroids (0.05% augmented betamethasone, fluocinonide, clobetasol).
- Recalcitrant cases may require systemic corticosteroids, preferring prednisolone oral suspension.
Lichen Planus
- Characterized by white reticular lines (Wickham striae) and papules on buccal mucosa.
- Common in individuals of color, leading to benign reactive melanosis in lesions.
- Erosive lichen planus can cause desquamative gingivitis with gingival erythema.
Mucous Membrane Pemphigoid (MMP)
- Large, irregular oral ulcers follow the rupture of bullae.
- Often presents as desquamative gingivitis when gingival tissues are the only areas affected.
- Ocular involvement may lead to complications like entropion and trichiasis, and severe scarring can result in blindness.
- Patients with MMP may show ocular inflammation and complications over time, necessitating careful management.
Key Notes
- Recognition and understanding of ulcerative lesions are critical for effective treatment planning.
- Biopsy and further laboratory testing may be required for accurate diagnosis in uncertain cases.
- Regular follow-ups are recommended to monitor systemic involvement and response to treatments.
