What are sharply marginated, elevated lesions containing clear fluid called?

1. Vesicles

2. Crusts

3. Scales

4. Ulcers

The correct answer is: Vesicles

The term for sharply marginated, elevated lesions that contain clear fluid is "vesicles." Vesicles are small blisters that form on the skin and are typically seen in conditions such as chickenpox, herpes simplex, and various forms of dermatitis. Their defining characteristics include their small size, elevation above the skin surface, and the presence of clear fluid, which sets them apart from other types of skin lesions. Crusts refer to dried blood, serum, or exudate on the skin surface, while scales are flakes or thin plates of exfoliated skin. Ulcers, on the other hand, are deeper lesions that often involve the loss of the skin's surface and can extend into the underlying tissues. Each of these options describes different skin conditions or lesions, but they do not fit the description of containing clear fluid and having sharply defined margins like vesicles do.
