Final answer:
Pustules are small, pus-filled elevations of the skin resulting from conditions such as acne or impetigo; they bear resemblance to vesicles but are characterized by their suppurative nature.
Step-by-step explanation:
Pustules are small raised bumps on the skin filled with pus, often resulting from an infection such as acne or impetigo. These skin lesions are similar to vesicles, which are fluid-filled, but pustules are characterized by their suppurative (pus-producing) nature.
Conditions like acne involve the infection of hair follicles, leading to the formation of various types of lesions, including pustules and comedones (whiteheads and blackheads). Impetigo, another common skin infection, can cause pustules along with bullae (larger fluid-filled blisters), which might rupture and become crusted sores, more so around the nose and mouth.
Pustules are small elevations of the skin that are similar in size and shape to vesicles, but contain pus. They are a type of skin lesion that resembles a cyst but with a less defined boundary. Pustules are fluid- or pus-filled bumps on the skin, and can be caused by various suppurative (pus-producing) infections.
