A solid elevation of skin that does not contain fluid is known as what?

A solid elevation of the skin that does not contain fluid is referred to as a papule. Papules are small, raised bumps typically less than 1 centimeter in diameter; they can vary in color and are often a sign of conditions such as acne, dermatitis, or other skin disorders. Their solid nature differentiates them from other types of skin lesions that may contain fluid, providing a clear indication of their physical characteristics.

In contrast, vesicles are small, fluid-filled blisters, macules are flat spots on the skin that are different in color but do not raise above the skin surface, and patches are large, flat areas of discoloration that similarly do not have elevated structures. Each of these other terms describes different types of skin lesions that do not fit the definition of a raised, solid elevation, reinforcing the distinction that makes papules unique.
