Acne vulgaris is the most common skin disease, affecting 85% of the population between the ages of 12 and 25 years.
Acne is characterized by noninflammatory and inflammatory lesions related to follicular hyperkeratinization, excessive sebum production, plugging of sebaceous glands, and P. acnes colonization.
is a severe form of acne with communicating cysts and abscesses.
is associated with elevated IgE levels, a family history of asthma and hay fever, and altered skin barrier function. Red, scaly lesions commonly occur on the face, cheeks, and flexor surfaces of the extremities in infants and young children.
Diaper dermatitis is a type of irritant contact dermatitis initiated by a combination of factors that include prolonged exposure to urine and feces; the infant frequently becomes infected secondarily with C. albicans.
is a poxvirus of the skin that produces pale, papular lesions filled with viral and cellular debris
(also known as German or 3-day measles) is a communicable disease characterized by fever, sore throat, enlarged cervical and postauricular nodes, and a generalized maculopapular rash that lasts 1 to 4 days.
Rubella has a faint pink-to-red maculopapular rash that develops on the face and spreads to the trunk and extremities in 1 to 4 days after the onset of symptoms.
is a highly contagious disease of children. Symptoms include high fever, enlarged lymph nodes, conjunctivitis, and a red rash that begins on the head and spreads to the trunk and extremities; it lasts 3 to 5 days. Bacterial and viral complications may accompany rubeola.
Rubeola, or the red measles, is a viral disease. It exhibits a high fever, malaise, enlarged lymph nodes, runny nose, and Koplik spots. Koplik spots are pinpoint white spots with an erythematous ring that are found on the buccal mucosa.
infection is a superficial fungal infection of the mouth (thrush)
is a benign disease of infants with a sudden onset of fever that lasts 3 to 5 days, followed by a rash that lasts 24 hours.
Roseola is a presumed viral infection of infants between the ages of 6 months and 2 years. A sudden onset of fever usually develops and lasts 3 to 5 days, and then the rash becomes evident.
Smallpox is a highly contagious, deadly disease that has been eradicated worldwide by vaccination.
Herpes zoster (shingles) is a viral eruption of vesicles on the skin along the distribution of a sensory nerve caused by latent activation of the VZV. Children with immune suppression develop more serious complications
Chickenpox (varicella) is a highly contagious disease caused by the VZV. Vesicular lesions occur on the skin and mucous membranes. Individuals are contagious from 1 day before the development of the rash until about 6 days after the rash develops.
Scabies is an itching lesion caused by the itch mite that burrows into the skin, forming papules and vesicles. The mite is very contagious and is transmitted by direct contact.
Pediculosis (lice infestation) is caused by blood-sucking parasites that secrete a toxic saliva and damage the skin to produce a pruritic dermatitis. Lice are spread by direct contact and are recognized by the ova, or nits, that attach to the shaft of body hairs.
Bedbugs are blood-sucking parasites that live in cracks of floors, furniture, or bedding and feed at night. They produce pruritic wheals and nodules.
Bedbugs live in the crevices and cracks of floors, walls, and furniture, and in bedding or furniture stuffing. They are nocturnal, emerging to feed in the darkness; they are attracted by warmth and carbon dioxide and attach to the skin to suck blood.
Flea bites produce a pruritic wheal with a central puncture site and occur as clusters in areas of tight-fitting clothing.
(port-wine stain) a deeper congenital malformation of the dermal capillaries, and salmon patches are more superficial vascular malformations.
are benign vascular tumors that emerge at birth and resolve spontaneously throughout the childhood years.
Hemangiomas are benign tumors that form from the rapid growth of vascular endothelium and result in the formation of extra blood vessels. They may be superficial or deep.
(distinct, raised vascular lesions) are more superficial
with larger and more mature vessels, are deeper lesions.
Erythema toxicum neonatorum
a benign, erythematous, accumulation of macules, papules, and pustules that appear at birth or 3 to 4 days after birth and then spontaneously resolve within a few weeks.
is characterized by small pruritic papules or vesicles that result from prolonged exposure to perspiration and subsequent obstruction of the eccrine ducts in infants.
Stevens-Johnson syndrome is a rare, serious disorder of your skin and mucous membranes. It's usually a reaction to a medication or an infection. Often, Stevens-Johnson syndrome begins with flu-like symptoms, followed by a painful red or purplish rash that spreads and blisters. Then the top layer of the affected skin dies and sheds.
Stevens-Johnson syndrome is a medical emergency that usually requires hospitalization. Treatment focuses on eliminating the underlying cause, controlling symptoms and minimizing complications.
Recovery after Stevens-Johnson syndrome can take weeks to months, depending on the severity of your condition. If it was caused by a medication, you'll need to permanently avoid that drug and others closely related to it.
Toxic epidermal necrolysis
TEN (the severe form of SJS) are severe, immune, blistering skin reactions to drugs.
Toxic epidermal necrolysis (TEN) is a potentially life-threatening dermatologic disorder characterized by widespread erythema, necrosis, and bullous detachment of the epidermis and mucous membranes, resulting in exfoliation and possible sepsis and/or death (see the image below). Mucous membrane involvement can result in gastrointestinal hemorrhage, respiratory failure, ocular abnormalities, and genitourinary complications.
Bullous impetigo is a rare variant of impetigo caused by S. aureus. This bacterium produces a toxin called exfoliative toxin, which causes a disruption in the desmosomal adhesion molecules. Bullous impetigo is highly contagious
