Aetiology
Superficial bacterial folliculitis is caused by the presence of Staphylococcus aureus or other bacteria in the hair follicle. The bacteria can enter the follicle through a break in the skin, such as a cut or scratch, or through a compromised immune system.
Diagnosis
Diagnosis of superficial bacterial folliculitis is typically made through a physical examination of the affected area. During the exam, the doctor may look for signs of infection, such as redness, swelling, or pus. In some cases, a skin sample (biopsy) may be taken to confirm the diagnosis.
Differential diagnosis
Differential diagnosis of superficial bacterial folliculitis includes other conditions that can cause skin irritation, such as acne, rosacea, contact dermatitis, and fungal infections.
Treatment
Treatment of superficial bacterial folliculitis typically involves antibiotics, either applied topically or taken orally. The doctor may also prescribe a topical antiseptic, such as benzoyl peroxide or salicylic acid, to help reduce inflammation and kill bacteria. In some cases, a steroid cream may be used to reduce itching and pain.
Prognosis
The prognosis for superficial bacterial folliculitis is generally good with proper treatment. Most cases will resolve within a few weeks, although some may take longer if the infection is more severe. It is important to keep the affected area clean and dry to help prevent the infection from spreading.
