What skin condition is characterized by bacterial infection of the pilosebaceous duct and is possibly linked to acne vulgaris?

Folliculitis is characterized by the inflammation and infection of hair follicles, specifically within the pilosebaceous unit, which consists of the hair follicle and its associated sebaceous gland. This skin condition can be a direct consequence of bacterial infections, most commonly caused by Staphylococcus aureus. Its connection to acne vulgaris lies in the fact that both conditions involve the same structures in the skin – the hair follicles and sebaceous glands.

In folliculitis, the infection results in red, inflamed bumps that can sometimes be filled with pus and can occur anywhere on the body where hair follicles are present. Acne vulgaris is similarly linked to the blockage and inflammation of these same ducts, often exacerbated by the same bacteria. Understanding this link provides insight into why maintaining healthy skin and hair follicles is essential in preventing both conditions.

In contrast, impetigo is generally a more widespread bacterial infection that usually affects the outermost layer of skin and is not specifically tied to the pilosebaceous unit. Warts are caused by viral infections (specifically human papillomavirus) and are not related to bacterial infections or pilosebaceous ducts. Tinea corporis, or ringworm, is a fungal infection affecting the skin and also does
