ManifestationThis section has been translated automatically.
Mostly healthy children without systemic involution are affected.
LocalizationThis section has been translated automatically.
Especially the face and the hairy head are affected. Occurrence on the whole integument is possible.
Clinical featuresThis section has been translated automatically.
Disseminated, blue to blackish, soft, prominent nodules and knots, with mostly intact surface. Extensive ulcerations are possible.
HistologyThis section has been translated automatically.
- Dense dermal infiltrate of histiocytic cells (immunohistology: CD1a pos./S100 pos.) with irregular, large nuclei and partially foamy cytoplasm. Erythrocyte diapedesis.
- Electron microscopy: Histiocytes with lamellar, false and true myelin figure-like inclusions. No Birbeck granules ( tennis racket ).
Differential diagnosisThis section has been translated automatically.
General therapyThis section has been translated automatically.
No causal therapy required. Spontaneous healing in 2-3 months.
External therapyThis section has been translated automatically.
To avoid superinfections and scars, it may be advisable to use antiseptic topicals such as 0.5-2% clioquinol cream/lotio(e.g. R049, R050, Linola-Sept) or disinfectant solutions with potassium permanganate (light pink), polihexanide (Serasept, Prontoderm) or quinolinol (e.g. Chinosol 1:1000 or R042 ).
Progression/forecastThis section has been translated automatically.
Spontaneous regression within the first years of life.
