Evaluation of Oral Cavity Cancer

  • The clinical features of the primary tumors arising from the mucosal surface of the oral cavity are:
    • Variable
  • The tumor may be:
    • Ulcerative
    • Exophytic
    • Endophytic
  • The gross characteristics of the lesion:
    • Are usually sufficient to raise the index of suspicion regarding the need for a biopsy to establish tissue diagnosis
  • Ulcerative lesions:
    • Usually are accompanied by an irregular edge and induration of the underlying soft tissues (

of the tongue.
  • Exophytic lesions may present either as a:
    • Cauliflower-like irregular growth or as flat, pink to pinkish white proliferative lesions
    • Occasionally, a red to pink velvety flat lesion is the only manifestation of superficially invasive or in situ carcinoma

  • Squamous cell carcinomas (SCC) with excessive keratin production and verrucous carcinomas:
    • Present as white heaped-up keratotic lesions with varying degrees of keratin debris on the surface

  • Papillary projections:
    • Often are seen in lesions that are accompanied or preceded by a squamous papilloma

  • Endophytic lesions:
    • Have a very small surface component:
      • But a substantial amount of soft-tissue involvement beneath the surface
