Study Notes
Oral Mucosal Pigmentations
- Oral mucosal pigmentations can be classified into three main categories: melanocytic, vascular, and exogenous.
Clinical Evaluation
- A pigmented area should be dry during evaluation.
- Digital palpation is used to assess changes in texture.
- The diascopy test (blanching) is used to aid in diagnosis.
- Pain assessment and clinical photographs are also part of the evaluation process.
- Biopsy is sometimes necessary for a definitive diagnosis.
Extrinsic Pigmentations
- Extrinsic pigmentations are superficial staining from pigments/dyes.
- Examples of extrinsic pigmentations include oral staining from food, beverage, or environmental factors.
Learning Objectives
- Recall the different types and features of melanocytic oral mucosal pigmentations.
- Recall vascular and systemic conditions that may result in oral mucosal pigmentations.
- Discuss the sources and features of exogenous pigmentations of the oral mucosa.
- Outline the malignant conditions that may present as oral mucosal pigmentations.
- Discuss the management of oral mucosal pigmentations where indicated.
