Case 1

Ulcerated invasive squamous cell carcinoma of the lip

  • Generally arises within a solar keratosis (actinic cheilitis) but may arise in a normal-appearing vermilion of the lip.
  • Many affected patients are smokers.
  • An irregular or firm nodule that ulcerates early.
  • Cancers on the lip are very likely to metastasise.

Wide surgical excision by an expert is mandatory. Staging investigations for advanced tumours may include ultrasound scanning, lymph node biopsy, CT and/or MRI scan.
