Folliculitis is infection or inflammation of one or more hair follicles resulting in a small pustule or red bump.[1] These are generally tender.[2] The condition may occur anywhere on hair covered skin.[1][2] Complications include cellulitis or abscess.[1]
It most commonly occurs due to a bacterial infection though less commonly may result from a fungal, viral, or noninfectious cause.[1] Risk factors include diabetes, obesity, antibiotic use, poor immune function, shaving and certain medications like lithium.[1] Diagnosis is generally based on symptoms and examination.[1]
Treatment depends on the underlying cause but is often conservative.[1] When due to Staph. aureus, while a few lesions may resolve on their own, larger numbers of lesions may be treated with antibiotic cream or pills.[1] When due to hot tube use, the outbreak will generally resolve without treatment within 10 days.[1] The condition is common.[1]
