Study Notes
Oral Complications
- Loss of resilience in the mouth can affect speech, tongue mobility, and mouth opening.
- A burning sensation, especially with spicy food, can be present.
- The lips, buccal mucosa, retromolar area, and soft palatal mucosa are the most common sites for oral complications.
Oral Lichen Planus
- A relatively common dermatosis affecting both skin and oral mucous membranes.
- 50% of patients exhibit oral and skin lesions.
- The etiology is multifactorial, with a cell-mediated immune response leading to basal cell layer degeneration. Stress can also be a contributing factor.
- Skin lesions involve flat-topped papules, often itchy and having a violaceous color, with fine scaling on the surface. These lesions are more commonly found on the trunk and flexor surfaces of the arms and legs.
- The genital mucosa is a frequent extra-oral site involved.
- Scratching often provides relief but can also lead to new skin lesions, known as the Koebner phenomenon.
Lichenoid Drug Eruptions
- Clinically and histologically similar to OLP.
- Certain drugs or their metabolites can act as haptens, triggering a lichenoid reaction (delayed hypersensitivity).
- Common culprits include penicillin, gold, NSAIDs, and sulfonamides.
- Skin lesions resemble those seen in OLP.
- Discontinuation of the offending drug typically results in resolution, with symptomatic treatment using topical steroids.
Classification of Soft Tissue Lesions
- Flat lesions: Macule, Patch
- Depressed lesions: Erosion, Fissure, Ulcer
- Raised lesions: Papule, Plaque, Nodule, Vesicle, Bulla, Pustule
Macule
- A flat circumscribed area of epidermis or mucosa, less than 1 cm in diameter.
- Distinguished from the surroundings by color, which can be red, pigmented (blue, brown, or black) due to melanin or foreign materials.
Patch
- A flat circumscribed area, neither elevated nor depressed, larger than 1 cm in diameter.
- Differentiated from its surroundings by color, texture, or both.
Papule
- A superficial elevated solid lesion, smaller than 1 cm in diameter.
- An example is lichen planus papules (skin lesions).
Plaque
- A flat solid raised area greater than 1 cm in diameter.
- Examples include lichen planus and leukoplakia.
Nodule
- A solid elevated mass of tissue, less than 1 cm in diameter.
- It extends deeper into the tissue than a papule. The overlying mucosa is not fixed and can be easily moved over the lesion.
- Examples include benign tumors like fibroma and lipoma.
Vesicle
- A circumscribed fluid-filled elevation in the mucosa, less than 1 cm in diameter.
- The fluid consists of lymph and serum.
- The epithelial lining is thin and can break down, leading to an ulcer.
- Common in viral infections like herpes simplex, herpes zoster, and chicken pox.
Bulla
- A fluid-filled elevation, greater than 1 cm in diameter.
- An example is Candida albicans tissue invasion.
Predisposing Factors for Candidiasis
- Changes in oral microbial flora following antibiotic administration.
- Chronic local irritants, such as dentures.
- Corticosteroids.
- Radiation of the head and neck.
- Age (infancy to old age).
- Immune status.
- Hospitalization.
- Smoking.
- Xerostomia (dry mouth).
Classification of Oral Candidiasis
-
Primary oral candidiasis:
- Acute: Pseudomembranous, Erythematous.
- Chronic: Pseudomembranous, Erythematous, Plaque-like, Nodular.
- Secondary oral candidiasis: Accompanied by systemic mucocutaneous manifestations like AIDS and DiGeorge syndrome.
Candida Associated Lesions
- Denture Stomatitis: The most prevalent site is the denture-bearing palatal mucosa. The denture acts as a vehicle for accumulating sloughed epithelial cells and protects microorganisms from salivary flow.
- Angular Chelitis: Inflammation at the corners of the mouth.
- Median Rhomboid Glossitis: A smooth red, diamond-shaped area, usually on the dorsal midline of the tongue.
Pseudomembranous Candidiasis (Thrush)
- Acute form: Predominantly affects patients medicated with antibiotics and immunosuppressant drugs.
- Chronic form: Associated with human immunodeficiency virus (HIV) patients and patients using steroid inhalers.
Erythematous Candidiasis (Atrophic)
- Characterized by diffuse borders, distinguishing it from erythroplakia which has a sharper demarcation.
- Found on the palate and dorsal surface of the tongue of patients using broad-spectrum antibiotics, smokers, or those using inhaled steroids.
Chronic Plaque-Type and Nodular Candidiasis (Candidal Leukoplakia)
- Characterized by white irremovable plaques that are indistinguishable from oral leukoplakia.
- Associated with malignant transformation.
