A. Macule
B. Plaque
C. Vesicle
D. Nodule
Correct Answer: B
Explanation: Plaques are elevated, flat-topped lesions that are often larger than papules.
18. What distinguishes a vesicle from a bulla?
A. Vesicles are smaller than bullae
B. Vesicles are deeper in the skin
C. Bullae are only found in bacterial infections
D. Vesicles are a type of tumor
Correct Answer: A
Explanation: Vesicles are defined as fluid-filled lesions less than 1 cm, while bullae are larger.
19. Which of the following is an example of a nodule?
A. A flat, discolored spot
B. A small papule with scale
C. A solid, raised lesion deeper than a papule
D. A vesicle with clear fluid
Correct Answer: C
Explanation: Nodules are deeper, solid lesions that extend into the dermis.
20. What is the significance of special staining techniques in dermatopathology?
A. They are used to measure lesion size
B. They help in the identification of specific tissue components
C. They solely detect bacteria
D. They are only used in cosmetic studies
