Who develops folliculitis?
Anyone can develop folliculitis wherever hair follicles are present on the body. The lesions in folliculitis most frequently involve the chest, back, and legs. Other common locations include the face, neck, thighs and buttocks. Although possible, it is rare to have it widespread all over the body. It does not affect the eyes, mouth, palms, or soles, where there are no hair follicles. Folliculitis probably affects all humans to some extent at some time during their lives.
Certain groups of people are more prone to develop folliculitis. People with diabetes and those with a compromised immune system (such as from HIV/AIDS, hepatitis, chronic illnesses, cancer, systemic chemotherapy, immune-suppressing drugs) may be more prone to develop folliculitis.
What are the causes of folliculitis?
Folliculitis can be caused by a large number of infectious organisms. Frequently folliculitis seems to be induced by irritating substances, environmental or anatomical defects, internal abnormalities and drugs. Differentiating these causes is very important if the physician is going to be able to treat the condition successfully.
How is folliculitis diagnosed?
The diagnosis of folliculitis is generally based on the appearance of the skin. In some situations, a microbial culture of the pus will help to detect a bacterial cause. It may be necessary to pull out some of the affected hairs and examine these microscopically using potassium hydroxide in order to detect fungal infections. Occasionally, a small skin biopsy may be used to help the doctor confirm the diagnosis. Infectious causes include bacteria, fungi, viruses, and parasites. Usually, no specific blood tests are needed in the diagnosis of common folliculitis.
