The article deals with the problems arising in the malignant skin neoplasms diagnosis. The inconsistency of modern methods of diagnostics on the basis of data obtainedwhile visual assessment of skin conditions is shown. The necessity of new means for early diagnostics of skin pathologies realization, for example, on the basis of a multispectral radiation source in the short-wave optical, ultraviolet and infra-red ranges proposed in the work is proved. A series of images of the skin area with a benign neoplasm were taken in selected optical bands, and differences in the images when illuminated with the used wavelengths were analyzed. The need in digital processing of the obtained images is demonstrated to minimize disturbances caused by irregularities in the skin covering as well as by the presence of non-informative skin structures such as hairs, keratinized epithelium, etc. The images were improved by means of their equalization as well as the complex use of the Laplace filter and the spatial maximumfilte
