    Study Notes

    Addison's Disease

    • Autoimmune disorder characterized by organ-specific circulating autoantibodies.
    • Rare cases may be caused by tuberculosis or fungal infections, often linked to HIV.
    • Adrenal insufficiency disrupts electrolyte and fluid balance, leading to severe clinical consequences.
    • Compensatory overproduction of adrenocorticotropic hormone (ACTH) leads to skin and mucosal pigmentation.
    • Initial pigmentation often appears on gingivae, buccal mucosa, and lips, resembling a suntan; can range from brown to nearly black.
    • Long-term management typically involves oral hydrocortisone, with dosage adjustments needed during stress or illness.
    • Insufficient steroid treatment may precipitate an Addisonian crisis, presenting severe health risks.

    Clinical Features of Addison's Disease

    • Symptoms include lassitude, anorexia, weakness, fatigue, and craving for salt due to low aldosterone levels.
    • Gastrointestinal issues such as diarrhea, nausea, and vomiting may occur alongside significant weight loss and low blood pressure.
    • Increased risk for hypotensive crises and potential association with chronic mucocutaneous candidiasis in different syndromes.

    Diagnosis of Addison's Disease

    • Diagnosed by monitoring low blood pressure and elevated ACTH levels.

    Management of Addison's Disease

    • After confirming diagnosis through histology, antifungal treatment for secondary infections may be necessary, though difficult to eradicate completely.
    • Miconazole gel is effective, sometimes requiring systemic options like fluconazole.

    Oral Tuberculosis

    • Oral tuberculosis is uncommon and usually associated with active pulmonary disease.
    • Typically affects elderly men with chronic undiagnosed pulmonary infections, showing symptoms like chest pain and weight loss.
    • Characterized by painless ulcers on the mid dorsum of the tongue with distinct angular or stellate shapes.

    Oral Crohn’s Disease

    • Presents with soft or tense swelling of lips, cobblestone buccal mucosa, erythematous gingivae, and painful linear mucosal ulcers.
    • Glossitis may arise from deficiencies in iron, folate, or vitamin B12 due to malabsorption.

    Ulcerative Colitis

    • Chronic inflammation of the large intestine leading to ulceration, with oral manifestation linked to pyostomatitis vegetans and related anemia.

    Coeliac Disease

    • Permanent intolerance to gliadin, resulting in inflammation of the small intestine and villous atrophy.
    • Malabsorption can lead to deficiencies, particularly iron and folic acid; can present various oral lichen planus types.

    Lichen Planus

    • Cutaneous lichen planus appears as dusky pink papules with Wickham's striae; typically occurs in flexor regions and other sites.
    • Histological features include hyperkeratosis, lymphocytic infiltrate, and significant basal cell destruction.

    Lichenoid Reactions

    • Induced by various triggers, including drugs, making clinical differentiation from lichen planus challenging.
    • Commonly involved drug categories include NSAIDs, ACE inhibitors, and antimalarials, emphasizing the need for thorough patient drug histories.

    Topical Lichenoid Reactions

    • Can be triggered by restorative materials like amalgam, localized to the areas in contact with materials.
    • Clinical features often mimic lichen planus or lupus erythematosus.

    Management of Lichenoid Reactions

    • Symptomatic treatments aim to manage flare-ups; many asymptomatic lesions require no intervention.
