What type of secondary lesion is characterized by being pus-filled and surrounding a hair?

1. Abscess

2. Superficial folliculitis

3. Cyst

4. Wheal

The correct answer is: Superficial folliculitis

The correct answer is that the type of secondary lesion characterized by being pus-filled and surrounding a hair is superficial folliculitis. Superficial folliculitis occurs when hair follicles become inflamed due to infection, often resulting in the formation of small, pus-filled bumps at the follicle site. This condition typically arises when bacteria infect the hair follicles, leading to redness and tenderness in the surrounding skin. The pus-filled nature of the lesions is a key characteristic, distinguishing it from other skin lesions. The context surrounding this condition is important as it showcases the role of hair follicles in certain types of infections. In superficial folliculitis, the inflammation closely follows the hair shafts, facilitating the identification of these lesions. The other types of lesions mentioned do not encapsulate both the pus-filled characteristic and the association with hair follicles. An abscess is a localized collection of pus that can occur in various tissues but isn't necessarily associated with hair follicles specifically. A cyst is a closed sac that may contain fluid or semi-solid material, which can be pus-filled in some cases, but does not specifically surround hair follicles. A wheal is a raised, itchy area of skin that typically indicates an allergic reaction, usually without a pus-filled content.
