    • Mucoepidermoid Carcinoma:

      • Recognize this as the most common malignant salivary gland tumor.

      • Describe its histopathology, consisting of mucous cells, epidermoid (squamous) cells, and intermediate cells.

    • Adenoid Cystic Carcinoma:

      • Understand its clinical behavior: slow-growing but highly infiltrative with a poor long-term prognosis.

      • Identify perineural invasion as its most important hallmark feature, which explains symptoms like pain and numbness.

      • Recognize its classic cribriform (“Swiss cheese”) pattern on a histology slide.

Would you like me to create a new quiz based on these more detailed objectives?

14. Systemic Manifestations

Of course. Here are the revised objectives with all points related to medications and pharmacology removed.

Revised Lecture Objectives

After this lecture, you should be able to:

Gastrointestinal (GI) Disorders

  • Gastro-oesophageal Reflux Disorder (GORD)

    • Differentiate between physiological gastro-oesophageal reflux and GORD based on frequency and effects on the oesophagus.

    • Identify the characteristic location and appearance of dental erosion caused by GORD.

  • Inflammatory & Granulomatous Conditions

    • Recognize the specific oral manifestations of Crohn’s disease, including mucosal cobblestoning, lip swelling, and full-width gingivitis.

    • Describe the clinical appearance of pyostomatitis vegetans, including its “snail track” ulcerations, and understand its significance as an oral marker for inflammatory bowel disease.

    • Define orofacial granulomatosis and list the systemic diseases it may be associated with, such as Crohn’s disease and sarcoidosis.

    • Describe the oral lesions associated with ulcerative colitis, such as severe aphthae.

  • Malabsorption Syndromes

    • List the common oral signs associated with Coeliac disease, such as recurrent aphthous ulcers, glossitis, and angular cheilitis.

  • Other GI Conditions

    • Explain the pathophysiology of pseudomembranous colitis, including the role of Clostridium difficile and its link to recent antibiotic use.

Liver and Renal Disease

  • Liver Disease

    • Identify key extra-oral clinical signs that are suggestive of underlying liver disease, such as jaundice and spider naevi.

  • Renal Disease

    • Describe the orofacial manifestations of chronic renal failure, including xerostomia, mucosal pallor, and uraemic stomatitis.

    • Identify common oral complications for a renal transplant patient, such as gingival overgrowth, and link them to the required post-transplant immunosuppressive state.

Haematological and Immunological Disorders

  • Haematological Disorders

    • Clinically differentiate between the glossitis caused by iron deficiency (smooth, depapillated tongue) and that caused by Vitamin B₁₂/folic acid deficiency (raw, beefy tongue).

    • Recognize the key oral signs of amyloidosis (macroglossia) and understand its association with multiple myeloma.

  • Human Immunodeficiency Virus (HIV) Infection

    • Identify and describe the oral lesions strongly associated with HIV (Group I lesions), including candidosis, hairy leukoplakia, and Kaposi’s sarcoma.

    • Explain the clinical significance of hairy leukoplakia as a potential indicator of progression to AIDS.

    • Recall the CD4 cell count threshold that defines the transition from HIV disease to AIDS.

  • Connective Tissue Disease

    • Describe the oral lesions of lupus erythematosus and recognize their clinical similarity to oral lichen planus.

Clinical Application and Referral

  • Based on a patient’s oral signs, determine when it is appropriate to investigate for an underlying systemic disease or refer them to a medical or specialist practitioner.

  • Recognize the classic triads of features for:

    • Melkersson-Rosenthal syndrome (facial swelling, fissured tongue, facial palsy).

    • Heerfordt’s syndrome as a manifestation of sarcoidosis (salivary/lacrimal swelling, facial palsy, uveitis).
