Study Notes

Red and White Oral Lesions

Oral mucosa can appear white due to various factors, including increased keratin production (hyperkeratosis), abnormal thickening of the stratum spinosum (acanthosis), fluid accumulation, toxic chemical exposure, or microbial infections (fungal pseudomembranes).
Red lesions can result from epithelial atrophy (reduced epithelial cells) or increased vascularization.

Differential Diagnosis

Various conditions can cause red and white variations in oral mucosa.
These include common issues like linea alba, Fordyce granules, leukoedema, as well as more serious conditions potentially linked to cancer, including leukoplakia, erythroplakia, oral submucous fibrosis, lichen planus, and various types of candidiasis.

Oral Lesions and Conditions

Oral Candidiasis: Different forms exist (acute pseudomembranous, acute atrophic, chronic atrophic, chronic hypertrophic)
Keratotic White Lesions: Conditions like stomatitis nicotina palati (smokers' palate).
Red and White Lesions with Possible Malignant Potential: Conditions like Leukoplakia, Erythroplakia, oral submucous fibrosis, including specific examples.

Specific Lesions

Linea alba: White line on buccal mucosa due to pressure or friction.
Fordyce's granules: Small yellowish-white spots due to ectopic sebaceous glands.
Leukoedema: Diffuse, filmy, white appearance on buccal mucosa, disappears when stretched.
Lichen planus: Oral lesions with different textures (reticular, papular, plaque-type, erythematous, and ulcerative), frequently with white and red elements.
Epithelial Hyperplasia: Increased cell proliferation on the oral mucosa, usually in response to chronic irritation. This appears as white and/or red papules or plaques.
Burns (chemical, thermal): Characterized by an irregular shape with white pseudomembrane or erythema, depending on the burn type.
Radiation mucositis/Mucositis: Secondary to radiation therapy for head and neck cancers, there's redness, followed by pseudomembrane covering. Often with greyish, white slough.
Koplik's spots: Small white spots, frequently seen in measles.
Denture Sore Mouth (DSM) and Papillary Hyperplasia (PH): Linked to denture use, with varying levels of severity, from red spots to hyperplastic red palate.
White spongy nevus: Rare genetic condition with bilaterally symmetrical thick plaques on buccal mucosa, often asymptomatic.

Treatment and Management

Treatment options vary based on the specific condition and severity. They often involve managing underlying causes (like smoking cessation), providing topical treatments (like anti-fungal medication), and in some cases surgical intervention.
Observation, supportive measures, and palliative treatments are also crucial aspects of management.
