Soft Tissue Tumours of the Oral Cavity

  • Irritation fibroma — the most common benign oral soft-tissue overgrowth (reactive).
  • Pyogenic granuloma — vascular, bleeds easily; the 'pregnancy tumour' (epulis gravidarum) when hormone-related.
  • Peripheral giant cell granuloma — occurs only on the gingiva/alveolar ridge; bluish-purple.
  • Kaposi sarcoma — HHV-8; associated with HIV/AIDS.
  • Hemangioma — most common in infancy (vascular).

Approach

Most reactive lesions are managed by excision + removing the irritant; biopsy confirms diagnosis.

Exam Tips ⭐
