Which lesion type is specifically described as a fluid-filled structure less than 1 cm?

Bulla
Pustule
Vesicle
Scale

The correct answer is: Vesicle

The correct answer is the vesicle, as it is characterized specifically as a small, fluid-filled lesion that measures less than 1 cm in diameter. Vesicles are typically filled with clear serous fluid and can be found in various dermatological conditions, such as herpes simplex virus infections or contact dermatitis. Their small size distinguishes them from bulla, which are similar but larger, typically over 1 cm. Understanding this distinction is important for identifying skin conditions accurately. Pustules, while also fluid-filled, contain purulent (pus) material rather than clear fluid and are often associated with inflammatory conditions like acne. Scales, on the other hand, refer to flakes or dry patches of skin, usually indicating conditions such as psoriasis or eczema, and do not involve fluid accumulation at all. Therefore, the definition and characteristics of a vesicle are what set it apart in this question as the correct answer.
