A Non-Healing Tongue Ulcer in a Smoker
Mr. D is a 61-year-old construction foreman with a painless ulcer on the left lateral tongue that has been present for 10 weeks. He has smoked 1 pack per day for 45 years and drinks two to three beers most evenings. The ulcer is 1.8 cm with rolled borders, indurated, and fixed to deep tissue. He was prescribed two courses of antibiotics and an antifungal without improvement. A 2 cm firm submandibular lymph node is palpable. There is no trismus or dysphagia. He takes aspirin 81 mg daily. He is worried that a biopsy will spread the cancer and asks whether he can just wait. He has not seen a dentist in 8 years.
1. What is your leading diagnosis and what is the next step? Explain why the previous treatments failed and why you would not simply observe.

Oral squamous cell carcinoma (OSCC) is the leading diagnosis: a non-healing, indurated ulcer on the lateral tongue in a heavy smoker and drinker, with a firm submandibular node. The next step is an incisional biopsy at the edge of the ulcer, including adjacent normal tissue, not an excisional biopsy. Antibiotics and antifungals failed because there is no infection; a 10-week ulcer is beyond the 2-week threshold for observation.
Do not prescribe another course of antibiotics. Do not observe. The node should be assessed by imaging, not by watchful waiting. An excisional biopsy of the tongue lesion would compromise margins and staging. Fine-needle aspiration of the node may be done by the head and neck team, but the primary biopsy establishes the diagnosis. Refer urgently to oral and maxillofacial surgery or head and neck oncology.
2. How would you counsel the patient about the biopsy, and what imaging and referrals would you arrange? Include the rationale for neck imaging and the significance of depth of invasion.

Explain that a biopsy is safe and does not spread cancer; the risk of tumor seeding is negligible compared with the risk of delayed diagnosis. Arrange contrast-enhanced CT of the neck and chest, and MRI of the tongue if available, to assess depth, midline involvement, and nodal disease. Refer within 1–2 weeks.
Depth of invasion predicts occult nodal metastasis: depth greater than 3–4 mm generally warrants elective neck dissection or sentinel node biopsy, even with a clinically N0 neck. His palpable node already suggests nodal disease, so staging imaging is essential. PET-CT may be used for advanced disease or to exclude distant metastasis. Aspirin does not need to be stopped for a biopsy; follow local protocols for surgery.
3. What advice would you give about his remaining mucosa, and what does field cancerization mean for follow-up?
Read the worked answer
Field cancerization means the entire upper aerodigestive mucosa has been exposed to carcinogens and carries genetic changes, so he is at risk for second primary tumors. Counsel complete smoking cessation and alcohol reduction; refer to cessation services. Explain that surveillance is lifelong: every 1–3 months in the first year, then less frequently, with palpation of the neck and examination of all mucosa.
HPV status is relevant mainly for oropharyngeal cancer; routine p16 testing is not required for oral cavity OSCC but may be done by the oncology team. Chemoprevention is not established. Any new white or red patch, ulcer, or swelling should be biopsied. He should maintain oral hygiene and see a dentist before radiation if planned. Emphasize that early detection of a second primary improves outcomes.
