HistoryThis section has been translated automatically.
DefinitionThis section has been translated automatically.
A disease belonging to the cutaneous non-Langerhans cell histiocytoses in the narrower sense (see xanthogranulomas below) with the formation of brownish maculopapular foci. So far in the international literature about 70 cases have been published (Polat Ekinci A et al.2017).
However, the independent nature of the entity is now disputed.
According to recent findings, there is overlap with juvenile xanthogranuloma or with other non-Langerhans cell histiocytoses.

m:w=1:1
ManifestationThis section has been translated automatically.
In a larger series (n=11), the initial manifestation was at 8 months (3-36 months).
LocalizationThis section has been translated automatically.
Lesions are first expected on the face (cheeks 22%, eyelids 13%, forehead 13%, ears 10%) in a large proportion of patients, followed by trunk and proximal extremities (Polat Ekinci A et al 2017); no mucosal involvement.
Clinical featuresThis section has been translated automatically.
Slightly raised, brownish-yellowish, symptomless papules with a smooth surface. No mucous membrane infestation.
HistologyThis section has been translated automatically.
Differential diagnosisThis section has been translated automatically.
Langerhans cell histiocytosis (histological differentiation)
Urticaria pigmentosa: Darier sign positive
cutaneous mastocytoma: Darier sign positive
Differential differentiation from other non-Langerhans cell histiocytoses is difficult or impossible.
TherapyThis section has been translated automatically.
Wait, as spontaneous regression often occurs (after 2-5 years with formation of atrophic, pigmented scars). CO 2 lasertreatment is possible if the patient wishes to undergo a pronounced therapy (but there is an increased risk of scarring!).
Good effects were achieved with topical 1% rapamycin (Habeshian K et al. 2019).
Progression/forecastThis section has been translated automatically.
HV persisted for several years on average (after 5 years, about 50% of patients heal without therapy with mild scarring and hyperpigmentation - Polat Ekinci A et al. 2017).
