[Accuracy of the clinical diagnosis in malignant melanomas]

Histologic findings and clinical data of 411 patients with malignant melanomas treated in 1952 up to june 1977 reveal an improvement of diagnostic accuracy. Within the last years, fewer patients were referred to the clinic with extensive tumor growth or with metastases. A change from the levels of invasion V and IV to III is evident. Further improvement to level II and I with a corresponding smaller tumor thickness is appearing in outlines.
