Forms of Acne
When sebaceous glands produce too much oil and that oil then combines with dead skin cells, follicles become blocked and then create acne---inflamed, clogged pores, blackheads and pimples. Acne afflicts between 17 and 45 million people in the United States, according to the University of Maryland Medical Center, and although women tend to have acne for a longer period of time, men are actually more likely to get acne and have more severe cases of it. Several forms of acne exist and vary in severity.
Acne vulgaris consists of lesions that include blackheads, whiteheads, nodules, cysts and pustules, and is the most common type of acne. This type of acne usually affects adolescents but can continue into adulthood and generally occurs on the face, back and chest, according to The Acne Group. Mild acne vulgaris consists of blackheads and whiteheads with pustules and papules sometimes present. Moderate acne vulgaris consists of inflamed, painful lesions and can result in scarring. Severe acne vulgaris can consist of scar producing painful nodules and cysts with inflammation and swelling.
Acne rosacea typically affects people over the age of 30 and appears as a red rash on the cheeks, forehead, nose and chin, and can affect the eyes. This type of acne is more common in women, but more severe in men, according to Acne.org. In advanced stages, it can thicken the skin on the nose.
Acne conglobata is the most severe form of acne vulgaris in which there are numerous large lesions with widespread blackheads, according to Acne.org. This type of acne first appears between the ages of 18 and 30 years old, and can cause severe disfiguring and scarring of the skin.
Acne fulminans is the abrupt onset of acne conglobata and usually affects young men with severe ulcerating acne that causes extreme scarring. This type of acne is associated with aching joints and a fever.
Gram-negative folliculitis is a type of rare acne occurring as a result of long-term antibiotic treatment of acne vulgaris and is a bacterial infection characterized cysts and pustules, according to Acne.org. Accutane is often effective in treating gram-negative folliculitis.
Pyoderma faciale affects only females, usually between the ages of 20 to 40 years old. This type of acne features large, painful lesions, nodules and pustules which can cause scarring. This type of acne comes on abruptly and can occur in women who have no history of acne, according to Acne.org. It does not last longer than a year, but causes severe damage to skin during that time and is confined to the face.
