Which of the following is the definition of a bulla?
A fluid-filled blister >0.5cm in diameter
What is a vesicle?
Fluid- filled blister <0.5mm in diameter
Which of the following is true?

B & C
Which of the following best describes erosion?
Partial loss of epithelium that is secondary to inflammation
Which of the following tests are frequently used for histopathology?
Immunofluorescence
Which of the following options accurately describe an indurated lesion?
A lesion that is firm upon palpation in tissue that would normally be soft.
When diagnosing a patient, we use a surgical sieve to prevent missing out possibilities in our differential diagnosis. A recommended surgical sieve is NIRDS, which option is wrongly represented?
A) N, Neoplastic
B) I, Iatrogenic
C) R, Reactive
D) S, Systemic
B
What is the term for a fluid filled blister <0.5cm in diameter?
Vesicle
A patient present in your clinic with a lesion that feels firm upon palpation on his cheek. How can you describe this lesion?
Indurated
Which model of the below is best used to assess a patient’s pain level?
SOCRATES
Which of the following statements is true?
A) Atrophy is characterised by thickening of the epithelial layer
B) Leukoplakia is a histologic diagnosis, not a clinical description
C) Sessile lesions are firmly attached to the mucosa by a broad base
D) Vesicles are fluid-filled blisters of more than 1cm in diameter
C
Which of the following is correctly defined?
A) Erosion is the loss of epithelium presenting with a yellow or whitish gray pseudomembrane
B) Macule is a well defined raised with color or texture change
C) Papule is a well defined flat lesion less than 0.5mm in diameter
D) Sessile is an exophytic lesion firmly attached to the mucosa with a broad base
D
What are the 5 guiding categories for coming up with differential diagnosis?
Neoplastic, Infectious, Reactive, Developmental, Systemic
Which of the following describes a macule?
A well defined flat lesion with colour or texture changes
Describing intra-oral lesions requires accuracy, so as to minimise miscommunications between different care providers. Which of the following is an accurate descriptor to the respective types of lesion?
A) Bulla- a fluid-filled blister <0.5cm in diameter
B) Induration - a lesion that is firm upon palpation in tissue that would normally be soft
C) Leukoplakia - a white lesion that rubs away when scrapped
D) Macule - a well-defined elevated lesion with colour or texture changes
B
What is the difference between erosion and an ulcer?
Erosion is a loss of partial thickness of epithelium while ulcer is a loss of full thickness of epithelium.
Define induration.
Firm upon palpation in tissue that would normally be soft
A bulla is defined as a fluid-filled blister ___ in diameter
> 0.5cm
Vesicles and bullae are both types of fluid-filled blisters. What is the key difference between them?
Size
Which of the following is a solid mass visible or palpable within or underneath the mucosa?
Nodule
Which of the following demonstrates a correct definition?
A) Erosion: redness of mucosa
B) Plaque: a well-defined elevated lesion >0.5cm on skin or mucosal surface
C) Ulcer: a fluid-filled blister <0.5cm in diameter
D) Nodule: a well-defined elevated lesion < 0.5cm in diameter
B
Which is the correct formula for ‘pack years’?
(No. of packs/day) x (No. of years smoked)
