Childhood psoriasis.

Cases of plaque psoriasis in children <2 years of age have also been published.

Tendentially, the prevalence increases with age.

A prevalence of about 1% is assumed for all children and adolescents.


Genetic predisposition

Triggers, e.g. infections, Köbner phenomenon, emotional stress, obesity, passive smoking, paradoxical reaction under tumour necrosis factor (TNF) α-blockers. Otherwise, drug triggers in children are rather rare.

Sharply demarcated, erythematous plaques with whitish-silvery scaling.

The diagnosis can be made clinically.

A thorough family history is useful.

In some cases, a biopsy must be done to confirm the diagnosis.

If tinea corporis cannot be clearly ruled out clinically, a mycology should be done.

It is important to take a history of joint complaints, GI complaints and diabetes mellitus.

If the diagnosis of tinea corporis cannot be clearly ruled out clinically, mycology should be performed

Poriatic nail changes are already possible in childhood.

Mostly on the capillitium, elbows, periumbilical, knee and rima ani. However, almost any localisation can be affected

In young children, nappy psoriasis may occur.

-Psoriatic arthritis

-Chronic inflammatory bowel disease is associated

-Adult metabolic syndrome
