Small, mobile lesions that are typically filled with pus are often referred to as?

Pustules are small, raised, inflamed lesions that are typically filled with pus. They are a common skin condition associated with acne and other inflammatory skin conditions. The pus in a pustule usually contains dead white blood cells, bacteria, and cellular debris, which contribute to its appearance.

The term "pustule" specifically refers to this type of lesion characterized by its fluid-filled cavity and inflammatory nature, differentiating it from other types of skin lesions. Cysts, while also skin lesions, are generally deeper, larger, and often filled with a thicker material rather than pus. Comedones refer to clogged hair follicles (blackheads or whiteheads) and do not involve pus. Nodes are solid, raised bumps that typically indicate a more chronic condition and do not have the purulent quality associated with pustules.

Understanding the characteristics of different skin lesions is crucial for estheticians in providing accurate skin assessments and treatments.
