Summary

The melaninbodies in nevuscellnevus, which are published in literature, are elucidate in own electronmicroscopic examinations. A functional attribute of the nevuscell is the formation of melanin, which are observed in celltyp A and B, but not in typ C (Mishima). The melaninbodies have characteristic features with internal structuration and double-conturate outsidemembran. Further degradations and hints on lysosomale residualbodies are found.

Zusammenfassung

Die nach der Literatur bekannten Melaninkörper im Naevuszellnaevus werden durch eigene elektronenmikroskopische Untersuchungen erläutert. Ein funktionelles Charakteristicum der Naevuszelle ist die Melaninbildung, die zwar im Zelltyp A und B, aber nicht im Typ C beobachtet wird (Mishima). Die Melaninkörper im Naevuszellnaevus weisen spezielle Züge mit innerer Strukturierung und einer doppelkonturierten Außenmembran auf. Weiterhin finden sich Degradationen und Hinweise auf lysosomale Residualkörper.
