Study Notes
Pemphigus Vulgaris, Mucous Membrane Pemphigoid, and Bullous Pemphigoid: Clinical Manifestations and Diagnosis
- Pemphigus Vulgaris: Presents with thin-walled bullae on noninflamed base, positive Nikolsky sign, and oral lesions in 60% of cases.
- Pemphigus Vulgaris: Lab tests include biopsy showing acantholysis, positive Tzanck smears, and indirect/direct immunofluorescent antibody tests for specific IgG.
- Pemphigus Vulgaris: Differential diagnosis includes acute viral infection, erythema multiforme, and recurrent aphthous stomatitis.
- Pemphigus Vulgaris: Treatment involves early diagnosis and a combination of corticosteroids and immunosuppressive drugs.
- Mucous Membrane Pemphigoid: Affects mucous membranes primarily, with skin involvement in 5-10% of cases.
- Mucous Membrane Pemphigoid: Age over 50 years, female:male ratio 2:1, and sites commonly affected include gingival, buccal mucosa, palate, conjunctiva, and skin.
- Mucous Membrane Pemphigoid: Lab tests show no acantholysis in biopsy, negative Tzanck smears, and positive indirect/direct immunofluorescent antibody tests.
- Mucous Membrane Pemphigoid: Differential diagnosis includes pemphigus vulgaris, bullous pemphigoid, erythema multiforme, and lichen planus.
- Mucous Membrane Pemphigoid: Treatment involves early diagnosis and various options based on disease severity, including topical or systemic corticosteroids and immunosuppressive drugs.
- Bullous Pemphigoid: Characterized by autoantibodies against bullous pemphigoid antigens, affecting older individuals, with cutaneous and oral manifestations.
- Bullous Pemphigoid: Presents with intensely pruritic, erythematous, urticarial-like plaques, tense bullae, and multiform oral lesions.
- Bullous Pemphigoid: Differential diagnosis includes erosive lichen planus, and skin lesions commonly occur on the scalp and limbs.
Oral Lesions and Complications: A Detailed Overview
- Hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber disease) is a rare autosomal dominant disorder characterized by abnormal vascular dilatations in skin, mucous membranes, and visceral organs, with red macules or papules as lesions.
- Venous varices, characterized by bluish-red dilated veins, are common, especially in the elderly, and can be found on the tongue and lower lip, turning white under pressure.
- Diagnosis of hereditary hemorrhagic telangiectasia is typically based on clinical examination, with angiography being useful for diagnosis and treatment planning. Lesions within the bone in the maxilla and mandible may exhibit a honeycomb appearance.
- Treatment for hereditary hemorrhagic telangiectasia may involve stabilization or regression in early childhood, and options such as selective embolization, sclerosing therapy, and laser therapy.
- Pyogenic granuloma, consisting of hyperplastic granulation tissue, often occurs in the gingiva and is more common in women. Chronic irritation and hormonal changes during pregnancy are common etiological factors.
- Peripheral giant cell granuloma is a rare hyperplastic connective tissue response, more common in women over 20 years of age, often found in the gingiva between the 1st molars and incisors. Diagnosis is made by biopsy, and treatment involves excision.
- Erythroplakia refers to a red patch on oral mucous membranes and is clinically divided into homogeneous and speckled forms. It is more likely to be premalignant or malignant than leukoplakia, especially in individuals between 50-70 years of age. Diagnosis is by biopsy, and treatment involves excision.
- Kaposi sarcoma, common in patients with AIDS, presents as red-brown on the skin or red-blue in the oral mucosa and can be flat or nodular in shape. Diagnosis is by biopsy, and treatment may involve surgical treatment, low-dose radiotherapy, or chemotherapy.
- Drug reactions in the oral cavity can result from systemic or local contact with an allergen. Contact stomatitis can occur due to reactions to cosmetics, toothpaste, gums, antibiotic mouthwashes, or dental restorations.
- Allergic stomatitis of systemic origin can be due to medication or food, resulting in red, swollen, cracked, or dry lips, and gingival redness and edema. Diagnosis involves anamnesis of contact with the allergen, biopsy, and response to treatment.
- Allergies can be classified as early (six hours) and delayed (forty-eight hours) reactions, and may manifest as erythema multiforme, lichenoid eruptions, angioedema, or vesiculobullous eruptions.
- Diagnosis of allergies may involve skin testing, medical history, and elimination diets to identify the allergen
Variants of Normal and Common Benign Conditions in Oral Soft Tissues
- Interdental papillae are affected to varying degrees, while nonkeratinized mucosa remains entirely unaffected.
- Physiologic pigmentation may intensify in areas of chronic trauma or inflammation, such as along the occlusal bite line of the buccal mucosa.
- Occasionally, a biopsy may be necessary to rule out melanoma, especially if changes in size, shape, or pigmentation are noted, or if a flat lesion becomes raised.
- Fordyce granules are sebaceous glands that appear white to yellow in color, generally presenting in clusters and may be slightly raised.
- Gingival grafts, harvested from the patient's palate, are raised and pale, easily recognizable and should not be mistaken for pathology.
- Fissured tongue is often asymptomatic but can become noticeable following the onset of unrelated symptoms, such as burning mouth syndrome.
- Geographic tongue is an inflammatory condition with a map-like appearance and can change daily, rarely requiring biopsy.
- Stomatitis erythema migrans can affect various oral mucosal sites, presenting as subtle circular lesions with white borders.
- Fibromas, the most encountered oral soft tissue lesions, are firm, exophytic, and generally asymptomatic, but may become bothersome due to repetitive trauma.
- Surgical excision is the treatment for fibromas, with no malignant potential but should be excised if the clinical diagnosis is uncertain.
- Tori and exostoses are benign bony growths, with tori specific to the midline hard palate and anterolateral lingual mandible, and exostoses involving the buccal aspect of the maxilla or mandible.
- Tori and exostoses can be mistaken for mucosal growths and are covered by either keratinized or nonkeratinized mucosa, depending on their location.
