An exanthem is a widespread erythematous rash that is accompanied by systemic symptoms such as fever, headache and malaise. Pityriasis rosea, Gianotti Crosti syndrome, Laterothoracic exanthem and Kawasaki disease are distinctive eruptions but the cause(s) are usually unknown and may be multiple. For most patients with non-specific exanthems no treatment is required as the condition is usually short-lived and resolves spontaneously.
Herpes viruses 6 and 7 have most often been associated with pityriasis rosea but in general, the cause or causes are unknown.
A solitary oval herald patch appears a week or two before an eruption of smaller but similar plaques appear predominately distributed in a fir tree pattern on the trunk.
The Gianotti Crosti syndrome (papulovesicular acrodermatitis, papular acrodermatitis of childhood, acrodermatitis papulosa infantum) is a characteristic papular rash arising in young children aged 6 months to 12 years. Over the course of 3 or 4 days a profuse eruption of erythematous macules, papules, plaques and sometimes vesicles develops first on the thighs and buttocks, then on the outer aspects of the arms, and finally on the face. Laterothoracic exanthem is also known as Asymmetric Periflexural Exanthem of Childhood (APEC). The rash usually starts in the armpit or groin and gradually extends outwards, remaining predominantly on one side of the body. The exanthem predominantly affects perioral and genital areas but may be diffuse, with swollen fingers and toes that later peel. Kawasaki disease is usually self-limiting and resolves spontaneously without treatment within 4-8 weeks.
Herpes zoster, or shingles, is a painful blistering rash caused by reactivation of the herpes varicella-zoster virus.
Herpes zoster can occur in childhood but is much more common in adults, especially the elderly, sick or immune suppressed.
The first sign of herpes zoster is usually pain, which may be severe, in the areas of one or more sensory nerves, often where they emerge from the spine. Post-herpetic neuralgia is defined as persistence or recurrence of pain more than a month after the onset of shingles. The chosen drug should be stopped if it does not produce the desired effect or causes unacceptable side effects at appropriate dose and duration.
Amitriptyline, imipramine, dothiepin, clomipramine, desipramine and doxepin have been shown to have analgesic effects in patients with neuropathic pain, independent of their antidepressant action. Tricyclics may also have analgesic effect when used topically, but no topical formulation is available in New Zealand.
Although SSRIs have some analgesic properties and are safer, they appear to be less effective than the tricyclics. These have widely differing methods of action so it is logical to try other agents if the first is unsuccessful. Gabapentin may have an action on the alpha delta 2 subunit of a calcium channel and inhibit glutamate release.
The causative viruses for chickenpox (varicella), measles (morbilli), rubella, roseola, fifth disease (erythema infectiosum), hand foot and mouth disease, and smallpox (hopefully now eradicated) are known and result in distinctive patterns of rashes and prodromal symptoms. Drug eruptions can also result in a wide range of similar presentations, including morbilliform and pityriasis rosea-like rashes. The virus is highly contagious from 1to 2 days before the rash appears and until all the blisters have formed scabs. The rash is associated with moderate to high fever, headache, upper respiratory symptoms, vomiting and diarrhoea. Exposure to varicella virus during pregnancy may cause viral pneumonia, premature labour and rarely maternal death.
Consider prescribing oral aciclovir (antiviral agent) in those older than 12 years or immunocompromised patients. Vaccination with live attenuated varicella vaccine is effective, but this is currently not part of the immunisation programme for children in New Zealand.
Measles (morbilli, rubeola) still causes more than a million childhood deaths each year in undeveloped countries.
Measles is highly contagious from 2 days prior to symptoms to at least 5 days after the onset of rash.
The prodrome includes fever, malaise, anorexia, followed by conjunctivitis (red eyes), cough and coryza. Measles-associated complications include otitis media, corneal ulceration enteropathy, glomerulonephritis, pneumonia and sepsis. Infection during pregnancy increases the risk of premature labour and delivery, and fetal loss.
Rubella (German measles) is a mild febrile illness associated with lymphadenopathy and a pale pink erythema.


Complications are rare with rubella in healthy infants and adults but infection in the first trimester of pregnancy has a 50% chance of causing miscarriage, stillbirth or congenital rubella syndrome. Combined measles , mumps and rubella (MMR) vaccine is currently part of routine immunisation programmes in most industrialised countries, including New Zealand. Roseola infantum (erythema subitum) is due to herpes virus 6, which may also be asymptomatic, and possibly also by type 7. Fifth disease (erythema infectiosum) is due to parvovirus B19 and most commonly affects young children. Hand, foot and mouth disease is a common, very infectious, mild and short-lasting condition most often affecting young children during the summer months.
After an incubation period of 3 to 5 days, flat small blisters appear on the hands and feet, and painful ulcers appear in the mouth. Send Home Our method Usage examples Index Contact StatisticsWe do not evaluate or guarantee the accuracy of any content in this site.
As the lesions resolve the papules may become inflamed (red and crusted) or necrotic (black scabs) and may leave punctate scars. Describe the impact and treatment of molluscum contagiosum in patients infected by human immunodeficiency virus.
Treatment with natalizumab in patients with multiple sclerosis (MS) appears linked with JC virus (JCV) infection, which can lead to a rare and often fatal demyelinating disease of the central nervous system called progressive multifocal leukoencephalopathy (PML) that destroys the myelin that protects nerve cells.

Exanthems during childhood are usually associated with viral infection and represent either a reaction to a toxin produced by the organism, damage to the skin by the organism, or an immune response.
Most likely they are reaction patterns due to a similar pathway of immunological consequences of viral infections and other triggers. Morphology is somewhat variable but a dry surface and inner circlet of scaling are typical. It is an uncommon rash affecting young children (especially girls), and is thought to be due to a viral infection. It may spread to the face, genitalia, hands or feet and may persist for up to twelve weeks. In some cases it is associated with known superantigens such as streptococci but the precipitating cause may be viral in others. However, 15-20% of cases will have some damage to coronary arteries and approximately 2% of patients will die from a heart attack. It is infectious, resulting in chickenpox in those who have never developed primary immunity, both from virus in the lesions and in some instances the nose and throat. In uncomplicated cases recovery is complete in 2-3 weeks in children and young adults, and 3 to 4 weeks in older patients. Polypharmacy can be useful to allow lower doses to achieve analgesia but side effects and drug interactions can be risky. More potent opioids are sometimes required short term, but can result in escalating dose requirements. They have an effect on the inhibitory serotonergic pathway, noradrenergic pathway, sodium channels, NMDA receptors and adenosine receptors. In doses of up to 500 mg bd it is associated with many adverse effects including severe allergic rashes (toxic epidermal necrolysis), hepatic enzyme induction, hyperlipidaemia, hyponatraemia and weight gain. Many exanthems are associated with common winter and summer viruses including respiratory and enteroviruses. It is spread by airborne respiratory droplets or through direct contact with blister fluid. Approximately 25% of fetuses become infected and may remain asymptomatic, or develop herpes zoster at a young age without previous history of primary chickenpox infection. In cases of inadvertent exposure to the virus, varicella-zoster immune globulin if given within 96 hours of initial contact can reduce the severity of the disease though not prevent it. Two or three days into the prodrome phase, Koplik spots (oral papules) appear, followed 24-48 later by the exanthem. It is available as a single antigen preparation or combined with live attenuated mumps or rubella vaccines, or both.
Congenital rubella infection results in major birth deformities hence females at least should be vaccinated in adolescence.
An infected person is contagious from 7 days prior to the rash appearing until 7 days later. It is characterised by high fever lasting for 3-5 days, rhinitis, cough, irritability and tiredness. The child is usually otherwise quite well, but occasionally has a slight fever and headache.


Congenital infection in the first or second trimester may result in fetal hydrops (3%), anaemia and intrauterine death (9%) but it does not result in congenital malformations.
The movement of cells with JC virus into the blood stream may provide researchers with a possible reason why patients with MS develop PML. Risk factors associated with development of PML include receiving 24 or more natalizumab infusions, receiving other immunosuppressive treatments and testing positive for JCV antibodies in a blood test.
Among the 23 patients who received natalizumab treatment for two years, 10 patients (44 percent) had detectable viral DNA in one or more cell subtype, as did three of the 18 healthy volunteers (17 percent). Frohman MD, PhD, Maria Chiara Monaco PhD, Gina Remington RN, Caroline Ryschkewitsch MT, Peter N. The study was supported by the Division of Intramural Research funds (National Institute of Neurological and Communicative Diseases and National Institute of Allergy and Infectious Disease laboratories) and other sources.
There is widespread inflammation of small- and medium-sized blood vessels, in particular, the coronary arteries.
Like herpes simplex, the virus persists in selected cells of dorsal root ganglion before it is reactivated. Within one to three days of the onset of pain, crops of closely grouped erythematous papules develop within the unilateral dermatome(s).
Muscle weakness arises in about one in twenty patients because the motor nerves are affected as well as the sensory nerves. Anticholinergic effects include dry mouth, blurred vision, constipation, urinary hesitancy, tachycardia and ejaculatory difficulty. The dose should be very slowly increased over six weeks up to 400mg once daily, to reduce the risk of skin rash. It becomes more important to make a definitive diagnosis if the child has been exposed to pregnant women or immunocompromised patients. Complications are more common in adults and include streptococcal cellulitis, central nervous system infection, thrombocytopenia and pneumonia.
Combined measles, mumps and rubella (MMR) vaccine is currently part of routine immunisation programmes in most industrialised countries, including New Zealand. The pale pink erythematous rash begins on the face that spreads to the neck, trunk and extremities.
Vaccination schedules recommend a two-dose immunisation strategy, the first dose at 12-15 months, followed by a second dose at 4-6 years. As the fever subsides a mild toxic erythema may appear on the face and trunk and persists for 1 to 3 days. For these patients, blood was drawn at baseline and again at approximately three-month intervals to 10 months. Of the 49 total patients with MS, 15 (31 percent) were confirmed to have JCV in CD34+ cells and 12 of the 49 (24 percent) had it in CD19+ cells. Please see the article for additional information, including other authors, author contributions and affiliations, financial disclosures, funding and support, etc. Kawasaki disease is currently the leading cause of acquired heart disease in children in the United States and Japan. New papules continue to appear for several days, each blistering or becoming pustular then crusting over.
The pain may be continuous and burning with increased sensitivity in the affected areas, or a spasmodic shooting type, or, rarely, itching and crawling (formication). As there are differing adverse effects, it is sometimes worth trying several different agents. Although most prominent in the first few days, the rash can persist at least intermittently for up to six weeks. Blood also was drawn on a single occasion from 23 patients with MS receiving natalizumab for more than two years and from the 18 healthy volunteers. There is a 50% chance of complete recovery and in time some improvement can be expected in nearly all cases. The overlying skin is numb or exquisitely sensitive to touch (hyperaesthesia and allodynia). Individuals vaccinated prior to 1968 may require revaccination as vaccines used before this time may not have conferred life-long immunity. It is associated with postauricular and cervical lymphadenopathy, and arthralgia or arthritis in adults, which sometimes persists for months or years.
Other side effects include dry mouth, peripheral oedema, weight gain, abnormal gait, amnesia, confusion, hypaesthesia, abnormal thinking, dyspnoea, amblyopia.
