Folliculitis is defined as the inflammation or infection of the hair follicle. It can be superficial or deep. At first it looks like small red bumps or white-headed pimples around hair follicles. Acne represents a noninfectious form of folliculitis.
It can affect anywhere there are hairs, including chest, back, buttocks, arms and legs.
Races affected by folliculitis
Folliculitis can affect people of all races.
Age/Sex prevalance affected for folliculitis
It affects people of all ages. It occurs in both men and women but eosinophilic folliculitis occurs more frequently in males and Pityrosporum folliculitis is seen slightly more often in females.
Classification of folliculitis
Types of folliculitis:
•Sycosis barbae – this is the medical name for chronic folliculitis in the beard area of the face in men. It often affects the upper lip and it can be difficult to treat.. Numerous pustules develop in the hair follicles
•Hot tub folliculitis – This tends to affect people who use hot tubs a lot. The hot water encourages germs (bacteria) called Pseudomonas to grow. Showering after using the hot tub does not seem to reduce the chance of folliculitis.
•Gram-negative folliculitis – this is a type of folliculitis that may occur after acne has been treated with long-term antibiotics.
•Pseudo-folliculitis – this is not really a true folliculitis. It does look similar, as little lumps form at the bases of hairs.
Causes of folliculitis
It can be caused by an infection -bacterial, viral, fungal, or parasitic or have a noninfectious etiology, most commonly due to follicular trauma, inflammation, or occlusion.
Risk factors for folliculitis
Conditions that make patients more susceptible include frequent shaving, immunosuppression, long-term antibiotic use, occlusive clothing and/or occlusive dressings, exposure to hot humid temperatures, diabetes mellitus and obesity.
Signs and symptoms of folliculitis
Folliculitis signs and symptoms include:
•Clusters of small red bumps or white-headed pimples that develop around hair follicles
•Pus-filled blisters that break open and crust over
•Red and inflamed skin
•Itchy burning skin
•Erythema Toxicum Neonatorum
•Fire Ant Bites
•Irritant Contact Dermatitis
•Pruritic papular eruption of HIV disease
•Subcorneal Pustular Dermatosis
Investigation of folliculitis
Diagnosis is mainly based on the appearance of the lesion.
Testing a sample of the fluid in the pimples or a sample of tissue can help your doctor learn what is causing the infection.
Investigation of folliculitis
Lesions that are more inflamed usually respond well to warm compresses with or without the use of a topical antimicrobial.
For deep lesions empiric treatment with oral antibiotics that cover gram-positive organisms should be considered.
Deep folliculitis is best approached with warm compresses, followed by incision and drainage once a pustular head develops.
Diet for folliculitis
Because folliculitis is more common in individuals who are obese, weight reduction may be helpful.
Prognosis of folliculitis
Prognosis is good as often it is self-limiting which means that it gets better on its own, without treatment.
