Excoriated acne is a mild acne accompanied by extensive excoriations caused by the person picking at the pimples (that is, scratching or squeezing them). [1] [2]
Acne, also known as acne vulgaris, is a long-term skin condition that occurs when dead skin cells and oil from the skin clog hair follicles. Typical features of the condition include blackheads or whiteheads, pimples, oily skin, and possible scarring. It primarily affects skin with a relatively high number of oil glands, including the face, upper part of the chest, and back. The resulting appearance can lead to anxiety, reduced self-esteem, and, in extreme cases, depression or thoughts of suicide.
Tretinoin, also known as all-trans retinoic acid (ATRA), is medication used for the treatment of acne and acute promyelocytic leukemia. For acne, it is applied to the skin as a cream, gel or ointment. For leukemia, it is taken by mouth for up to three months.
Hyperpigmentation is the darkening of an area of skin or nails caused by increased melanin.
Acne keloidalis nuchae is a destructive scarring folliculitis that occurs almost exclusively on the occipital scalp of people of African descent, primarily men.
A comedo is a clogged hair follicle (pore) in the skin. Keratin combines with oil to block the follicle. A comedo can be open (blackhead) or closed by skin (whitehead) and occur with or without acne. The word "comedo" comes from the Latin comedere, meaning "to eat up", and was historically used to describe parasitic worms; in modern medical terminology, it is used to suggest the worm-like appearance of the expressed material.
Excoriation disorder is an obsessive-compulsive spectrum mental disorder that is characterized by the repeated urge or impulse to pick at one's own skin to the extent that either psychological or physical damage is caused.
Azelaic acid (AzA) is an organic compound with the formula HOOC(CH2)7COOH. This saturated dicarboxylic acid exists as a white powder. It is found in wheat, rye, and barley. It is a precursor to diverse industrial products including polymers and plasticizers, as well as being a component of a number of hair and skin conditioners. AzA inhibits tyrosinase.
The term acne cosmetica refers to acne caused by or aggravated by cosmetics. The mechanism is thought to be chemically induced plugging of the pilosebaceous orifice. This became a significant problem for dermatologists in the 1970s and 1980s, but with the improved formulations produced by cosmetic chemists in the decades since, a diagnosis of acne cosmetica has become relatively rare in dermatological practice.
Feline acne is a problem seen in cats primarily involving the formation of blackheads accompanied by inflammation on the cat's chin and surrounding areas that can cause lesions, alopecia, and crusty sores. In many cases symptoms are mild and the disease does not require treatment. Mild cases will resemble dirt on the cat's chin, but the "dirt" will not brush off. More severe cases, however, may respond slowly to treatment and seriously detract from the health and appearance of the cat. Feline acne can affect cats of any age, sex or breed, although Persian cats are also likely to develop acne on the face and in the skin folds. This problem can happen once, be reoccurring, or even persistent throughout the cat's life.
Tropical acne is unusually severe acne occurring in the tropics during seasons when the weather is hot and humid.
Acne conglobata is a highly inflammatory disease presenting with comedones, nodules, abscesses, and draining sinus tracts.
Neonatal acne, also known as acne neonatorum, is an acneiform eruption that occurs in newborns or infants within the first 4-6 weeks of life, and presents with open and closed comedones on the cheeks, chin and forehead.
Halogen acne is caused by iodides, bromides and fluorides (halogens) that induce an acneiform eruption similar to that observed with steroids.
Lupus miliaris disseminatus faciei , also known as acne agminata, is a disease with a similar appearance to acne vulgaris. The cause of LMDF is unknown.
Prurigo gestationis is an eruption consisting of pruritic, excoriated papules of the proximal limbs and upper trunk, most often occurring between the 20th and 34th week of gestation.
Occupational acne is caused by several different groups of industrial compounds, including coal tar derivatives, insoluble cutting oils, and chlorinated hydrocarbons.
Acne with facial edema occurs uncommonly, and is associated with a peculiar inflammatory edema of the mid-third of the face.
Tufted folliculitis presents with doll's hair-like bundling of follicular units, and is seen in a wide range of scarring conditions including chronic staphylococcal infection, chronic lupus erythematosus, lichen planopilaris, Graham-Little syndrome, folliculitis decalvans, acne keloidalis nuchae, immunobullous disorders, and dissecting cellulitis.
A pimple is a kind of comedo that results from excess sebum and dead skin cells getting trapped in the pores of the skin. In its aggravated state, it may evolve into a pustule or papules. Pimples can be treated by acne medications, antibiotics, and anti-inflammatories prescribed by a physician, or various over the counter remedies purchased at a pharmacy.
Superficial pustular folliculitis is a superficial folliculitis with thin-walled pustules at the follicular openings.
