What is the medical term for a small, raised, solid pimple or swelling on the skin?

The medical term for a small, raised, solid pimple or swelling on the skin is referred to as a papule. Papules are typically characterized by their elevated nature, being firm to the touch and not filled with fluid. They can vary in size and may be indicative of various skin conditions, which makes understanding this term essential for anyone studying dermatology or skin disorders.

Pustules, on the other hand, are similar in elevation but contain pus, making them distinct from papules. A bulla is a larger fluid-filled blister, which differs in size and content from papules. Macules are flat, discolored areas of the skin that do not have any elevation, further highlighting the defining characteristic of a papule as a solid, raised element.
