Which term refers to the inflammatory disease of the sebaceous glands marked by papules and pustules?

The term that refers to the inflammatory disease of the sebaceous glands marked by papules and pustules is acne vulgaris. This condition is primarily characterized by the development of comedones (clogs in the pores), papules, pustules, and, in some cases, cysts, leading to inflammation and infection of the skin. Acne vulgaris commonly occurs due to a combination of factors, including excess sebum production, hormonal changes, and bacteria, particularly Propionibacterium acnes. The presence of papules and pustules indicates an inflammatory response in the skin, which is typical of acne.

In contrast, contact dermatitis is caused by allergic or irritant reactions on the skin's surface, atopic dermatitis (eczema) involves chronic inflammation often related to allergies and asthma, and psoriasis is another skin condition that manifests as scaly patches due to overproduction of skin cells. Each of these conditions has different underlying causes, symptoms, and affected areas, distinguishing them from acne vulgaris.
