Triage — Airway & Malignancy Red Flags
Screen for airway emergency, then for occult malignancy
The first task at every oral or pharyngeal presentation is to exclude two emergencies. Airway compromise — stridor, drooling, tongue or floor-of-mouth swelling, Ludwig's angina, or severe angioedema — demands immediate airway control, admission, and intravenous antibiotics or steroids as indicated, before any diagnostic workup proceeds.
With the airway secured, screen for occult malignancy. An ulcer persisting beyond two weeks, induration, contact bleeding, a cervical node, trismus, weight loss, persistent or referred otalgic pain, dysphagia, or odynophagia — particularly against a background of tobacco, areca nut, or alcohol use — mandates an expedited biopsy pathway. The cost of a timely biopsy is trivial against the cost of a missed oral cancer; the threshold to biopsy is deliberately low.
- Airway emergency — stridor, drooling, tongue / floor-of-mouth swelling, Ludwig's angina, angioedema → secure airway, admit
- Ulcer >2 weeks, induration, contact bleeding → expedite biopsy
- Neck node, trismus, weight loss, persistent or referred otalgia, dysphagia, odynophagia → malignancy workup
- Tobacco, areca nut / gutka, alcohol exposure raises pre-test malignancy probability
★ High-yield pearls (chapter-wide)
- Any oral ulcer persisting beyond two weeks is squamous cell carcinoma until biopsy proves otherwise — do not re-treat empirically.
- Erythroplakia is the most ominous oral lesion — treat any unexplained red patch as severe dysplasia or carcinoma until histology says otherwise.
- Induration, fixation, contact bleeding, a neck node, trismus, or referred otalgia alongside an oral lesion are malignancy until excluded — biopsy and image, do not observe.
- A non-scrapeable white patch is leukoplakia (a diagnosis of exclusion); a scrapeable one is usually candidiasis — wipe it and look.
- Areca nut, gutka, and pan masala drive oral submucous fibrosis and oral cancer — ask every patient with burning or restricted mouth opening, and enrol them in lifelong surveillance.
- Vesiculobullous disease needs a perilesional biopsy with direct immunofluorescence — routine histology alone misses pemphigus and mucous membrane pemphigoid.
- Tonsil, base-of-tongue, or adult cystic neck-node lesions warrant p16/HPV testing — HPV-associated oropharyngeal cancer behaves and is staged differently.
- Most xerostomia is drug-induced polypharmacy — review the medication list before working up Sjögren syndrome.
- Grade and date every potentially malignant disorder — OPMD review is every 3–6 months, severe dysplasia every 3 months, and biopsy is repeated whenever the lesion changes.
