Folliculitis Flashcards
What is folliculitis?
Folliculitis is a common dermatological condition characterised by inflammation of the hair follicles, which can be caused by infection, chemical irritation, or physical injury.

Severe folliculitis can lead to scarring or permanent hair loss.
What is a furuncle?
A furuncle (boil) is a deeper, and more pronounced infection of the hair follicle.
What are the infectious causes of folliculitis?
Infectious causes include bacterial (most commonly Staphylococcus aureus), fungal (Candida species or dermatophytes), and viral (Herpes simplex virus).
What is the most common bacterial cause of folliculitis?
The most common bacterial cause of folliculitis is Staphylococcus aureus.
What is spa pool folliculitis?
Spa pool folliculitis may develop due to infection with Pseudomonas aeruginosa.
What are the non-infectious causes of folliculitis?
Non-infectious causes include chemical folliculitis (caused by topical steroids, oils, or tar) and physical folliculitis (due to shaving, tight clothing, or occlusive dressings).
What are general features of folliculitis?
General features include small red bumps or white-headed pimples around hair follicles, itching or tenderness, and pus-filled blisters that break open and crust over.
What is folliculitis barbae?
Folliculitis barbae presents with lesions in the bearded area due to infection with Staphylococcus aureus.
What is pseudofolliculitis barbae?
Pseudofolliculitis barbae has a similar distribution to folliculitis barbae but is due to irritation rather than infection, predominantly affecting men of black African or African-Caribbean ancestry.
