Hidradenitis is the inflammation of which body part?

Hidradenitis refers specifically to the inflammation of the sweat glands, particularly the apocrine glands found in areas such as the armpits and groin. This condition often leads to painful lumps or abscesses that can become infected. It is a chronic inflammatory skin condition and is more common in individuals with certain underlying factors, such as obesity or metabolic syndrome. Recognizing that hidradenitis is tied to the function and health of sweat glands is crucial for understanding its pathophysiology and management.

The other options do not accurately reflect what hidradenitis targets. Nails, skin, and ears pertain to different types of conditions and would not be described as hidradenitis.
