Which skin condition is characterized by small, raised areas that do not contain fluid?

The skin condition characterized by small, raised areas that do not contain fluid is known as a papule. Papules are typically solid and can vary in color, texture, and size. They form due to an accumulation of cells or other materials in the skin, leading to localized areas of elevation. Papules are common in various skin conditions, such as acne, eczema, and some types of dermatitis.

In contrast, pustules are similar in appearance but contain pus, indicating an inflammatory response, typically associated with infections or acne. Keratosis refers to an abnormal growth of skin cells and can manifest in different forms, such as actinic keratosis, but does not specifically describe a raised area without fluid. Blisters, on the other hand, are specific lesions that form when fluid accumulates between layers of the skin, creating a clear or cloudy bubble. Therefore, the defining characteristic of a papule is its solid, fluid-free elevation, distinguishing it from these other skin lesions.
