OMFS-0105Malignant lesionsOncologyintermediateLateral tongue

Non-healing ulcer of the lateral tongue in a smoker

58-year-old male

Draft — educational study aid, pending faculty review.

§Chief complaint

Painful ulcer on the side of the tongue for 3 months

§Medical & dental history

  • 0130 pack-year smoking history
  • 02Daily alcohol intake
  • 03Hypertension on amlodipine
  • 04Irregular attender
  • 05No sharp restorations or trauma at the ulcer site

§Clinical examination

  • 01Indurated ulcer 25 mm on the left lateral border of the tongue with rolled everted margins
  • 02Restricted tongue protrusion, deviation to the left
  • 03Single firm, mobile 2 cm left level II lymph node
  • 04No trismus; airway patent

§Differential diagnosis

Squamous cell carcinomaIndurated non-healing ulcer with rolled margins and a node
Traumatic ulcerIdentifiable cause, heals in 2 weeks after removal
Tuberculous ulcerUndermined margins, systemic symptoms
Major aphthous ulcerRecurrent, soft base, no induration

§Final diagnosis

Moderately differentiated squamous cell carcinoma of the left lateral tongue, cT2 N1 M0

Induration is the single most important clinical sign — it distinguishes carcinoma from every soft-based ulcer. Duration beyond 3 weeks in a patient with tobacco and alcohol exposure mandates biopsy rather than empirical treatment.

§Investigations

  • 01Incisional biopsy from the ulcer margin, not the necrotic centre
  • 02Contrast MRI of tongue and neck — 24 mm lesion, depth of invasion 9 mm, single level II node
  • 03CT thorax — no metastasis
  • 04Full blood count, orthopantomogram for dental clearance

§Treatment plan

  • 01Multidisciplinary team discussion
  • 02Wide local excision with 1 cm clinical margins plus ipsilateral selective neck dissection (levels I-IV)
  • 03Reconstruction with a radial forearm free flap
  • 04Adjuvant radiotherapy based on final pathology

§Surgical procedure

  • 01Peroral hemiglossectomy with frozen section margin control
  • 02Selective neck dissection levels I-IV preserving accessory nerve, IJV and SCM
  • 03Radial forearm free flap inset, anastomosis to facial artery and IJV branch

§Histopathology report

Moderately differentiated invasive squamous cell carcinoma, size 24 mm, depth of invasion 9 mm, perineural invasion present, no lymphovascular invasion. Closest margin 6 mm. One of 32 nodes positive without extranodal extension. pT2 pN1.

§Follow-up & outcome

  • 01Adjuvant radiotherapy 60 Gy completed
  • 02Monthly review year 1, 2-monthly year 2
  • 03Speech and swallowing rehabilitation; disease-free at 30 months

§Clinical pearls / learning points

  • 01Any oral ulcer persisting beyond 3 weeks requires biopsy, whatever the presumed cause.
  • 02Depth of invasion, not surface diameter, drives T stage in the current AJCC system.
  • 03Biopsy the edge of the ulcer including adjacent normal tissue; the centre is often only necrosis.
