Emergency And Acute Medicine – Aphthous Ulcers
Overview:
Painful, ovoid or round ulcerations of the mucous membranes of the mouth, tongue, or genitals, commonly referred to as canker sores.
Etiology And Risk Factors:
The cause is unknown and likely multifactorial. Associations include immunologic dysfunction with altered cell-mediated immunity, infections, food hypersensitivities (e.g., gluten), vitamin deficiencies, pregnancy, menstruation, trauma, stress, ethnicity, immunodeficiency, and medications such as β-blockers and anti-inflammatory agents. Aphthous ulcers most commonly affect children and young adults, with peak onset between 10–19 years. They are the most common inflammatory ulcerative condition of the oral cavity, affecting 20–40% of the population, occur more frequently in women, and may be familial.
Clinical Features:
Minor aphthous ulcers account for 70–90% of cases and are typically <5 mm in diameter, painful, shallow, with necrotic centers, raised margins, erythematous halos, and a gray-white pseudomembrane. they affect non-keratinized mucosa of the anterior oral cavity heal within 10–14 days without scarring.< />pan>
Major aphthous ulcers (Sutton disease) are larger, deeper, more painful, last weeks to months, may scar, and are often associated with systemic disease.
Herpetiform aphthous ulcers present as clusters of numerous small ulcers that may coalesce; despite appearance, herpes simplex virus is not isolated.
History And Examination:
Patients often report a prodrome of burning or pricking 1–2 days before ulcer appearance. History should explore autoimmune disease, inflammatory bowel disease, Behçet disease, reactive arthritis, gluten sensitivity, HIV, malignancy, sexual history, and medication use. Examination focuses on oral lesions, hydration status, secondary infection, and signs of systemic disease.
Evaluation:
Diagnosis is clinical. Further workup is reserved for ulcers persisting longer than three weeks, recurrent severe disease, or associated systemic symptoms. Directed laboratory testing and biopsy may be indicated based on clinical suspicion.
Differential Considerations:
Trauma, medication reactions, viral and bacterial infections, erythema multiforme, autoimmune disease, inflammatory bowel disease, hematologic disorders, and malignancy must be considered, particularly in atypical or persistent cases.
Management Approach:
Treatment is guided by severity and duration, with the primary goal of pain control and inflammation reduction.
Therapeutic Options:
Mild to moderate disease is managed with avoidance of oral trauma and acidic foods, topical anesthetics, protective bioadhesives, topical anti-inflammatory agents, and antimicrobial mouth rinses.
Severe disease may require short courses of systemic corticosteroids or, in refractory cases, specialist-guided immunomodulatory therapy.
Disposition And Follow-Up:
Admission is reserved for patients unable to maintain oral intake, those with dehydration, or abnormal vital signs. Most patients may be discharged once pain is controlled and fluids are tolerated. Persistent lesions beyond two weeks warrant outpatient follow-up and further evaluation.
Clinical Pearls And Pitfalls:
Most aphthous ulcers are benign and self-limited, requiring only symptomatic care. Emergency clinicians should remain vigilant for underlying systemic disease in patients with severe, atypical, or persistent ulcerations.
