Read the first 7 Oral Diagnosis and Pathology flashcards as text

  1. A 45-year-old patient presents with a painless, firm swelling on the hard palate that has been present for years. Radiograph shows no bone destruction. The most likely diagnosis is:

    Answer: Pleomorphic adenoma

    Pleomorphic adenoma is the most common benign salivary gland tumor, frequently presenting as a slow-growing, painless firm mass on the hard palate.

  2. Which histologic feature is MOST characteristic of oral lichen planus?

    Answer: Civatte bodies and band-like lymphocytic infiltrate

    Oral lichen planus shows characteristic Civatte (colloid) bodies and a band-like subepithelial lymphocytic infiltrate at the basement membrane zone.

  3. A patient presents with multiple radiolucent lesions in the jaw and a history of multiple basal cell carcinomas of the skin. This presentation is consistent with:

    Answer: Gorlin-Goltz syndrome

    Gorlin-Goltz (nevoid basal cell carcinoma) syndrome is characterized by multiple odontogenic keratocysts, multiple basal cell carcinomas, and skeletal anomalies.

  4. The 'strawberry gingivitis' pattern with granulomatous inflammation is most associated with which systemic condition?

    Answer: Wegener granulomatosis (GPA)

    Granulomatosis with polyangiitis (Wegener's) classically produces strawberry-like hyperplastic gingivitis with a granulomatous histology.

  5. A ranula that dissects through the mylohyoid muscle into the neck is termed:

    Answer: Plunging ranula

    A plunging ranula occurs when mucous extravasation from the sublingual gland herniates through the mylohyoid muscle to present as a neck mass.

  6. Which stain is used to identify amyloid deposits in tissue sections, producing apple-green birefringence under polarized light?

    Answer: Congo red

    Congo red stain imparts a salmon-pink color to amyloid that shows characteristic apple-green birefringence under polarized light.

  7. Peripheral giant cell granuloma of the gingiva is most accurately classified as:

    Answer: Reactive hyperplasia

    Peripheral giant cell granuloma is a reactive hyperplastic lesion arising from periosteum or periodontal ligament in response to local irritation.
