What condition is primarily indicated by a raised, fluid-filled lesion?

• A. Patch
• B. Bulla
• C. Papule
• D. Plaque

Answer: (B)

A raised, fluid-filled lesion is primarily indicated by the term bulla. A bulla refers specifically to a large blister that typically measures greater than 1 centimeter in diameter and is filled with serous fluid. This condition can arise from various causes, such as friction, burns, or certain skin diseases. In contrast, other terms describe different types of skin lesions. A patch refers to a flat area of discoloration on the skin that is larger than a macule but does not contain fluid. A papule is a small, solid, raised lesion, often less than 1 centimeter, without fluid, such as in cases of acne or warts. A plaque is a raised area that is generally larger than a papule and may have a scale or be flat-topped, commonly seen in conditions like psoriasis. Understanding these distinctions is crucial for accurate identification and assessment in clinical practice.
