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
Main article: 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]
- Multiple oral fibromas may be seen in Cowden disease.[2][3]
- Histologically similar to fibrous papule.[4]
Microscopic
Features:[4]
- 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:[5]
- Diffuse & bilateral:
- Peutz-Jeghers syndrome.
- Addison's disease.
- Drug-induced.
- Smoker's melanosis.
- Focal:
- Vascular lesions.
- Amalgam tattoo.
- Melanocytic lesions.
- Melanotic macule.
- Blue nevus.
- Malignant melanoma.
Smoker's melanosis
General
- Benign.
- Seen in ~20% of smokers.[5]
- Presence of find (smoking) dose-dependent, i.e. longer heavier smokers are more likely to have it.
Gross
- Typically labial gingvia or buccal mucosa.[5]
Microscopic
Features:
- Basal melanosis.
- +/-Melanin incontinence.
