Oral pathology is a domain of dentistry. In the context of anatomical pathology, it can be lumped with head and neck pathology.

Odontogenic tumours and cysts

Oral neoplasms

Oral fibroma

General

  • Most common oral cavity tumour.[1]
  • Female predominance (female:male = 2:1), usually 30-50 years old.[1]

Microscopic

Features:[3]

  • Fibrous stroma.
  • +/-Collagen bundles.
  • Prominent (dilated) vessels.
  • Overlying (squamous) mucosa +/-hyperkeratosis +/-focal ulceration.[1]

Pigmented lesions of the oral cavity

A brief DDx of pigmented lesions:[4]

Smoker's melanosis

General

  • Benign.
  • Seen in ~20% of smokers.[4]
  • Presence of find (smoking) dose-dependent, i.e. longer heavier smokers are more likely to have it.

Gross

  • Typically labial gingvia or buccal mucosa.[4]

Microscopic

Features:

  • Basal melanosis.
  • +/-Melanin incontinence.
