Which oral lesion presents as a white patch that cannot be wiped off and is considered a potentially malignant disorder?
Answer: Leukoplakia
Leukoplakia is a white patch that cannot be wiped off (unlike candidiasis) and carries a 1–17% risk of malignant transformation, requiring biopsy.
A patient presents with multiple painful oral ulcers, a vesicular rash on the hands and feet, and fever. What is the most likely diagnosis?
Answer: Hand, foot, and mouth disease (HFMD)
HFMD, caused by Coxsackievirus A16, presents with oral ulcers plus vesicular skin lesions on hands and feet, typically in young children.
Ameloblastoma is most commonly found in which location?
Answer: Posterior mandible in the molar-ramus region
Approximately 80% of ameloblastomas occur in the mandible, with the molar-ramus region being the most common site.
Which radiographic finding is characteristic of a dentigerous cyst?
Answer: Well-defined unilocular radiolucency surrounding the crown of an unerupted tooth
A dentigerous cyst forms around the crown of an unerupted tooth, appearing as a well-defined unilocular radiolucency at the cementoenamel junction.
A biopsy shows 'squamous epithelium with keratin pearl formation, individual cell keratinization, and intercellular bridges.' What is the diagnosis?
Answer: Well-differentiated squamous cell carcinoma
Keratin pearls, individual cell keratinization, and intercellular bridges are classic histologic features of well-differentiated squamous cell carcinoma.
Which systemic condition is most commonly associated with multiple periapical cemento-osseous dysplasia lesions in African American women?
Answer: No systemic disease — it is a benign, reactive condition of unknown cause
Periapical cemento-osseous dysplasia (PCOD) is a benign reactive condition with no associated systemic disease; it requires only monitoring, not treatment.
