[Melanocytic nevi as one of the risk factors of melanoma malignum].

The paper presents the contemporary view on the melanocytic nevi and their role in the pathogenesis of skin malignant melanoma. There is a strong relationship between the presence of the melanocytic naevi and the incidence of melanoma malignum. Therefore dermatologists should pay close attention to patients from the risk group, with many common melanocytic naevi and atypical melanocytic naevi, family history of melanoma, bright fair skin, with history of sun burns. These patients should be thoroughly and regularly checked up. Examination should include photographic surveillance and dermatoscopy and every suspected mole should be excised with further histological examination. This kind of procedure intensifies the possibility of early recognition of melanoma malignum of the skin, which is crucial for successful treatment of this dangerous disease.
