Which chronic inflammatory condition affects the apocrine glands and often occurs in areas like the axilla and labia major?

Hidradenitis suppurativa is a chronic inflammatory condition that specifically targets the apocrine glands, which are found in areas such as the axilla (armpits) and the labia majora. This condition is characterized by painful, swollen lumps under the skin, which can lead to the formation of abscesses and tunnels under the skin (sinus tracts), making it distinct from other skin conditions.

Apocrine glands are specialized sweat glands that become active at puberty and are located in regions like the axilla and groin. In hidradenitis suppurativa, inflammation of these glands can lead to recurrent flare-ups and significant discomfort, along with possible scarring. This chronicity and location of the skin lesions are critical in understanding the nature of the condition, which sets it apart from other listed options.

In contrast, acne vulgaris primarily affects sebaceous glands and typically presents on the face, while pseudofolliculitis barbae is linked to ingrown hairs, often in the beard area. Folliculitis refers to the inflammation of hair follicles, which can occur anywhere on the body and is not specifically related to apocrine glands. Thus, understanding the specific involvement of apocrine glands in
