[Attempt at applying statistical methods to delimit melanoma types]

By means of the "multivariate variance analysis" ("MANOVA"; Friedrich and Olfert, 1977), we tried to differentiate the histologic types of malignant melanomas also by quantifiable criteria. The investigation depended upon data from 411 patients. Difficulties arose from incomplete data material. But in principle, the indication of this method is given in such problems. If the number of cases could be augmented, the method would be helpful as a support for diagnostic quality control.
