Gianotti, 1967; Crosti, 1955

Definition
This section has been translated automatically.

Reactive, intermittent, symmetrical, papular exanthema in young children, which has been described primarily in association with HBV infection, but can also be observed in connection with numerous other viral diseases (e.g. EBV infection, Coxsackie virus infection).

Occurrence/Epidemiology
This section has been translated automatically.

Worldwide spread.

Etiopathogenesis
This section has been translated automatically.

The pathogenesis is largely unexplained.

Self-limited Id reactions to viral and bacterial antigens are discussed.

In larger studies, the association with a viral infection has been proven in about 50% of patients (mostly EBV or hepatitis C/ B; more rarely Coxsackie viruses, cytomegaloviruses, adenoviruses, enteroviruses, RSV, parainfluenza virus, parvovirus B19, HHV-6, HHV-7, HIV). The occurrence of GCS in the context of an infection with mollusca contagiosa is not entirely rare.

In industrialized countries, Gianotti-Crosti syndrome is most frequently associated with EBV.

In individual cases, the occurrence has been associated with infections caused by β-hemolytic streptococci, Mycobacterium tuberculosis or with vaccinations against poliomyelitis, diphtheria, influenza or pertussis.

More often children with atopic diathesis are affected.

Manifestation
This section has been translated automatically.

Occurs in children between 6 months and 14 years of age. The average age of first manifestation is about 2 years.

Localization
This section has been translated automatically.

Preferably face, here especially cheeks, extremities (extensor sides), buttocks (symmetrical).

Clinical features
This section has been translated automatically.

After a short prodromal phase with a slight feeling of illness, subfebrile temperatures, pharyngitis, gastrointestinal symptoms, nausea and diarrhoea, the patient is impressed by intermittent, disseminated, red or brown, smooth or scaly, 0.1- 0.5 cm large, clearly raised papules and vesicles, which can also confluent in places to larger plaques (rather untypical).

The exanthema typically does not itch.

Often a Koebner phenomenon (isomorphism) can be detected (linear arrangement at externally irritated areas, e.g. in scratch marks).

Generalized lymphadenopathy (cervical, axillary, inguinal) and/or hepatomegaly (anicteric hepatitis) are possible.

Laboratory
This section has been translated automatically.

  • Detectable in 50-80% of cases: lymphocytosis, but also lymphopenia, eosinophilia, increased SPA.
  • Less frequently detected: serum transaminase elevation, positive hepatitis B or EBV serology, IgE elevated; detection of type I sensitization.

Differential diagnosis

General therapy
This section has been translated automatically.

Symptomatic.

External therapy
This section has been translated automatically.

Symptomatically with Lotio alba, 2% Polidocanol-Zinc shaking mixture R200 or 3%-Polidocanol ointment (e.g. Recessan) Glucocorticoids can generally be dispensed with.

Internal therapy
This section has been translated automatically.

For itching, oral antihistamines such as doxylaminosuccinate (for infants from 6 months of age, e.g. mereprine syrup 1-2 times 1 teaspoon/day).

Progression/forecast
This section has been translated automatically.

Favorable course. Exanthema and lymphadenopathy resolve spontaneously after 3-8 weeks. Any existing hepatitis generally takes a mild course. Only rarely transition to chronic aggressive hepatitis. Rare are post-inflammatory hyper- or hypopigmentations. Chronic or lethal courses have been described, but are absolute rarities.
