Papulosa juvenilis dermatitis L30.8

Sutton, 1956

Not very common (probably underdiagnosed) inflammatory disease of childhood of unknown etiology associated with lichenoid papules (probably closely related to atopic dermatitis).

Epidemiological figures are not known. It can be assumed that the disease is more likely to be underdiagnosed.

Unknown; a pathogenetic connection is suspected by rubbing on rough mats or in the sand. Possible constitutional tendency to lichenoid reaction, possibly atopic diathesis (in the study by Sardana et al. 2015 with >100 participants, about 50% of the children had atopic diathesis!) To what extent UV influences (accumulation in the summer months) play a role is unclear.

Children between the ages of 4 and 12, especially in the summer months. m>w.

Convince parents of the harmlessness of the findings or the spontaneous healing tendency.

Bathing with refatting additives such as Linola grease, Balneum Hermal F. In particular, after bathing, apply a cream with bland external agents such as Ungt. emulsif. aq., Linola Fett, Eucerin cum aq., Asche Basis Cream/Ointment.

Alternative: Urea is often added to the skin in a pleasant way, e.g. a 5-10% urea cream(urea cream hydrophilic 5 or 10% NRF 11.71.) or Excipial U Lipolotio.

Alternatively: anti-inflammatory ointments with 2% ichthyol (e.g. Ichthoderm).

If the inflammatory component is pronounced:

• short-term low concentrated external corticoids such as 0.5% hydrocortisone cream e.g. Hydrogalen, R121 or 0.05% Betamethasone-Lotio e.g. Betagalen® as finished preparation or Betamethasone-valerate emulsion hydrophilic 0.025/0.05 or 0.1% (NRF 11.47) as formulation.
• Alternative: temporary - topical calcineurin inhibitors.

Spontaneous healing after 6-9 weeks.
