Acne Vulgaris: A Useful Guide

Acne Vulgaris

Acne vulgaris is a common disease of the human skin which is characterised by areas of skin with multiple non inflammatory follicular comedones or papules and by inflammatory papules, nodules and pustules in its more severe forms. Acne vulgaris affects mostly the areas of skin with the densest population of sebaceous follicles including the areas of the back, the chest, and the face. Severe acne can be inflammatory; however, acne may also show up in a non inflammatory form.

Acne Vulgaris

Acne lesions are generally known as zits, spots, blemishes, or pimples. Acne lesions are caused by changes in pilosebaceous units that require androgen stimulation and which are skin structures consisting of a hair follicle and its associated sebaceous gland. Aside from scarring, its primary effects are psychological, including reduced self esteem. Acne usually appears during adolescence.

Acne aestivalis is a special form of polymorphous light eruption. It is a monomorphous eruption consisting of multiple papular lesions which are red and uniform. They reportedly occur after exposure to the sun. Acne conglobata is a highly inflammatory disease that has abscesses, nodules, and comedones, as well as draining sinus tracts. This condition generally begins between the ages of 18 and 30. It usually persists for an unusually long time, and may last until the patient is around 40 years old.

Acne cosmetica is a term referring to acne which is caused by or made worse by cosmetics. Some patients may not at first attribute their reactions to their cosmetics, however, may notice that their symptoms get worse after using certain lip products, sun block or face makeup.

Acne fulminans is one of the severest forms of skin disease, which is thought to be an immunologically induced disease in which elevated level of testosterone causes a rise in P acne and sebum bacteria. The condition is commonly treated with steroids. Acne mechanica is a form of acne that usually occurs following repeated physical trauma to the skin such as rubbing, which generally occurs from sports equipment or clothing. Acne medicamentosa is a form of acne that is aggravated or caused by medication. Since acne is normally considered a disorder of the philosebaceous units which are caused by hormones, the medications that trigger this form of acne are usually hormones.

Acne with facial edema is acne which occurs rarely, and is usually associated with a specific inflammatory edema of the mid third of the face. There are some conditions which mimic acne medicamentosa. The most common mimic is the yeast folliculitis which is produced by an overgrowth of the Malassezia species, often as a secondary to systematic or oral corticosteriods, or secondary to a broad based spectrum of antibiotics including tetracycline which is often used to treat acne.Acne miliaris necrotica consists of follicular vesicopustules, sometimes occurring as solitary lesions that are normally very itchy
