DefinitionThis section has been translated automatically.
A particularly stubborn, often permanently itchy variant of atopic eczema with efflorescences as in Prurigo simplex subacuta. The disease occurs in 2 clinical variants:
- prurigo chlorescences with signs of atopic eczema
- Prurigoefflorescences without other signs of atopic eczema
ManifestationThis section has been translated automatically.
This variant is described in childhood and as a late manifested form in adulthood.
Atopic eczema first manifested in childhood and adolescence: 5-10% of patients affected.
Atopic eczema first manifested in adulthood (after the 18th year of life): 3.2% of patients affected.

Clinical featuresThis section has been translated automatically.
Mostly colorful clinical picture with sharply defined efflorescences of different "acuity" from fresh to "healed scarred".
Initial efflorescences (usually not detectable): "Urticarial", eminently itchy, 0.2-0.5 cm large, red papules. In most cases, however, there is no "precursor efflorescence" but only a piercing, tortuous, localized itching in normal appearing skin.
Residual efflorescence (typical clinical finding): 0.3-0.5 cm large, centrally scratched, moderately raised, red or reddish brown papules covered with a crust or fresh granulation tissue. In addition, depending on the duration of the disease symptoms, white scars of varying age, or reddened, selenium hyperpigmented scars in the size of the pre-existing prurigopapules.
Typical is a punctual, painfully piercing itching, which is answered with a typical scratching reaction (spooning); then the itching stops abruptly. It is not uncommon, however, to develop scratching automatisms that are difficult to interrupt.
Notice! It is not the "disturbing efflorescences" but the punctual, tormenting itching that leads to the doctor!

S. Eczema, atopic.
It remains to be seen to what extent Dupilumab will be an effective therapeutic option in the treatment of this disease (Almustafa ZZ et al. 2019).
