HistoryThis section has been translated automatically.
Lewandowsky, 1921; Weidman et al., 1933
DefinitionThis section has been translated automatically.
Acquired (more rarely) or congenital (more frequently), mostly disseminated, elastic connective tissue nevus (elastoma) with proliferation of elastic, rarely collagen fibres. Primarily described by Weidmann et al. as a disseminated form in children (= elastoma juvenile), the elastic nevus can also occur in isolation in older adults (adult-onset elastoma), whereby actinic damage (UV damage) is discussed as the cause.

ManifestationThis section has been translated automatically.
Occurs from birth or in the first years of life, less frequently in late adulthood.
LocalizationThis section has been translated automatically.
Mostly multiple, especially the upper thorax area as well as the face and abdomen are affected.
Clinical featuresThis section has been translated automatically.
Densely packed, 0.2-0.4 cm large, whitish yellowish papules or flat, larger plaques.
HistologyThis section has been translated automatically.
Partial hyperpigmentation of the stratum basale, strong repair of the elastic fibres. In the upper and middle corium fragmented, disordered elastotic material. No significant change in the collagenous fibre architecture.
TherapyThis section has been translated automatically.
A therapy for the disease is not known. Excision for cosmetically disturbing localization.
Note(s)This section has been translated automatically.
In the meantime, the name Naevus anelasticus has become generally accepted because, contrary to earlier assumptions, no reproduction of the elastic fibres has taken place.
The disseminated nodular form (Dermatofibrosis lenticularis disseminata) can occur in families and be associated with osteopoietic disease ( Buschke-Ollendorf syndrome).
