Diagnosis: Oral Squamous Cell Carcinoma (OSCC) — Lateral Tongue

The image shows a lesion on the lateral/ventrolateral tongue with the following features:
  • Indurated, raised erythematous ulcer with a central granular/necrotic core
  • Surrounding white (leukoplakic) changes with irregular margins
  • Mixed erythroplakia + leukoplakia pattern ("speckled leukoplakia")
  • Induration visible on the raised borders
  • Poor dental hygiene and likely tobacco/betel nut use (stained teeth)
This morphology — a chronic indurated ulcer with mixed red-white changes on the lateral tongue — is the classic presentation of oral squamous cell carcinoma until proven otherwise.

Key Clinical Features Supporting OSCC

FeaturePresent in Image
Indurated, non-healing ulcer✅
Erythroplakia (red patch)✅
Leukoplakia (white patch)✅
Lateral tongue location (high-risk site)✅
Stained teeth (tobacco/betel use)✅

Risk Factors (Harrison's, p. 1094)

  • Tobacco (smoked or smokeless) and alcohol
  • Betel nut with slaked lime (common in South/Southeast Asia — likely context given dentition staining)
  • HPV (especially HPV-16) — increasingly important
  • Chronic local irritation

Differential Diagnosis

  1. Oral SCC (most likely)
  2. Traumatic ulcer (but would be painful, well-defined, heal within 2 weeks)
  3. Oral tuberculosis (rare; biopsy required to exclude)
  4. Deep fungal infection (histoplasmosis, mucormycosis)
  5. Granulomatosis with polyangiitis

Immediate Next Steps

  1. Incisional biopsy — mandatory; histopathology is the gold standard
  2. CT neck with contrast — assess regional lymph node involvement (staging)
  3. Chest imaging — screen for distant metastasis / synchronous primary
  4. Referral: Head & Neck Oncology / Oral & Maxillofacial Surgery
⚠️ Any indurated oral ulcer >2 weeks duration must be biopsied. Early-stage OSCC (T1/T2 without nodal spread) has a significantly better prognosis than advanced disease. Do not delay biopsy for empirical treatment.
