  1. A 45-year-old patient presents with a white patch on the lateral border of the tongue that cannot be wiped off. Biopsy reveals epithelial dysplasia. What is the most appropriate diagnosis?

    Answer: Leukoplakia

    Leukoplakia is a clinical term for a white patch that cannot be wiped off and has no other identifiable cause; dysplasia on biopsy confirms its premalignant potential.

  2. Which type of ameloblastoma is most commonly found in the posterior mandible and is characterized by islands of odontogenic epithelium within a fibrous stroma?

    Answer: Solid/multicystic ameloblastoma

    The solid/multicystic (conventional) ameloblastoma is the most common type, arising predominantly in the posterior mandible with classic histological patterns including follicular and plexiform subtypes.

  3. A patient with HIV presents with painless, bluish-purple nodules on the hard palate. What is the most likely diagnosis?

    Answer: Kaposi's sarcoma

    Kaposi's sarcoma is an AIDS-defining malignancy commonly presenting as blue-purple vascular lesions on the palate in HIV-infected individuals.

  4. A radiolucent lesion associated with the crown of an unerupted tooth is found on radiograph of a 20-year-old. Histology shows a thin epithelial lining with no dysplasia. What is the diagnosis?

    Answer: Dentigerous cyst

    A dentigerous cyst (follicular cyst) is the most common developmental odontogenic cyst, enclosing the crown of an unerupted tooth at the cementoenamel junction.

  5. Erythema multiforme most commonly affects young adults and is characterized by which pathognomonic skin lesion?

    Answer: Target (iris) lesion

    The target or iris lesion — concentric rings of erythema — is the hallmark cutaneous lesion of erythema multiforme.

  6. Which salivary gland tumor is most common overall and is characterized by a biphasic histology with both epithelial and mesenchymal-like components?

    Answer: Pleomorphic adenoma

    Pleomorphic adenoma (mixed tumor) is the most common salivary gland neoplasm, characterized by a mixture of epithelial cells and chondromyxoid stroma.

  7. A 35-year-old female presents with bilateral parotid swelling, dry eyes, and dry mouth. What autoimmune condition should be suspected?

    Answer: Sjogren's syndrome

    Sjogren's syndrome is an autoimmune exocrinopathy presenting with bilateral parotid enlargement, xerostomia, and keratoconjunctivitis sicca (dry eyes).
