VIDEO-CASE-PRESENTATION-REEL-DX

Aphthous ulcers

Patient will present as → a 22-year-old complaining of a painful sore for 2 days.  He denies any alcohol or tobacco use and otherwise feels fine.  Examination is significant for a 2-mm round ulceration with a yellow-gray center surrounded by a red halo on the left buccal mucosa

Painful ovoid or round ulcerations on the mucous membranes of the mouth, tongue or genitals: Commonly referred to as “canker sores”.

  • Prodrome of burning or prickling sensation of oral mucosa 1–2 days prior to the appearance of ulcers.
  • The vast majority of aphthous ulcers are benign, self-limited, and treated symptomatically.  
  • Physicians must consider underlying systemic cause of ulcers:
    • Inquire about patient or family history of:
      • Systemic lupus erythematosus (SLE)
      • Inflammatory bowel disease (IBD)
      • Behçet disease
      • Reiter disease
      • Gluten sensitivity
      • Cancer
      • HIV
      • Inquire about patient sexual history of syphilis or herpes virus
      • Inquire about current medications:
      • NSAIDs
      • β-blockers
  • Biopsy should be considered for ulcers lasting more than 3 wks
  • Diagnosis is made by history and clinical presentation.
    • Rule out oral manifestation of systemic disease: More likely if persists >3 wk or associated with constitutional symptoms.  Focus on symptoms of eyes, mouth, genitalia, skin, GI tract, allergy, diet history and physical exam

Treatment guided by severity and duration of symptoms. The goal is for symptomatic pain relief and reduction of inflammation.

  • Mild to moderate disease:
    • Avoid oral trauma/acidic foods
  • Topical anesthetic
    • Magnesium hydroxide/diphenhydramine hydrochloride 5 mg/5 mL in 1/1 mix swish and spit
    • Viscous lidocaine 2–5%: Applied to ulcer QID after meals until healed
  • Monitor PO status (especially in small children)
  • PO NSAIDs
  • Referral to a specialist if underlying disease suspected.

Question 1 Explanation: 
Aphthous stomatitis, also known as canker sores, are painful eruptions that affect the mucosal surface of the mouth. The cause is unknown. Lesions typically develop at the same time and resolve in 5 to 10 days. A viral cause has not been proved. A streptococcal bacterium has been implicated. The lesions recur at regular intervals and may correlate with the onset of menses in some women. Treatment consists of toothpaste swish therapy, triamcinolone acetonide (Kenalog in Orabase), or tetracycline solution swish and swallow. Severe cases may respond to systemic corticosteroids.
