Abstract
In 47 out of 61 bce's, melanocytes were detectable with the aid of Dopa-reaction. In 24 of these cases, the percentage of tumour cells was less 5%, and in 23 it was more. The melanocytes preferred the periphery of the epithelial tumour formations. Only when the proportion of melanocytes exceeded 5% were they also to be found in the central parts of the tumours. Generally the melanocytes were more numerous in the upper parts of tumours, next to the epidermis. Our findings strengthen the opinion, that bce is a tumour of the primary hair germ. Mit Hilfe der Dopa-Reaktion waren in 47 von 61 Basaliomen Melanozyten nachweisbar. Bei 24 war ihr prozentualer Anteil an den Tumorzellen geringer als 5% und bei 23 größer als 5%. Die Melanozyten bevorzugten die Peripherie der epithelialen Tumorformationen. Nur wenn mehr als 5% Melanozyten vorhanden waren, fanden sie sich zusätzlich in den zentralen Partien. Grundsätzlich waren die Melanozyten in den der Epidermis zugewandten Anteilen der Tumoren vermehrt. Unsere Ergebnisse bestärkten uns in der Ansicht, daß das Basaliom ein Tumor des primären Haarkeims ist.This publication has 15 references indexed in Scilit:
