Folliculitis(redirected from gram-negative folliculitis)
Also found in: Dictionary, Thesaurus, Medical.
an inflammation of a hair follicle caused primarily by staphylococci. Symptoms of folliculitis are redness and swelling, followed by the formation of a nodule having on its surface a pustule pierced by the hair. When only the orifice of the follicle is affected, ostial folliculitis results, which is usually resolved within a few days. A deep folliculitis, or a furuncle, develops when the tissues surrounding a follicle also become inflamed.
Treatment consists of wiping the skin around the pustules with a 2 percent solution of salicylic acid or camphor and covering them with a 2 percent solution of brilliant green or methylene blue.
