[Removal of melanocytic nevi as a prophylaxis and early recognition of cutaneous and mucous malignant melanoma].

In article 1240 melanocytic nevi were described in which 26 melanomas were found. The authors present necessity of early removal (excision) of dysplastic melanocytic nevi, pigmented lesions with high risk of malignant transformation, giant congenital melanocytic nevi before adolescence and nevi which are irritated constantly. Particularly dysplastic nevi and pigmented lesions with high risk often contain melanoma "in situ" or invasive melanoma. Such a procedure early done, prevents developing of tumor and makes possible early recognition of melanoma but the procedure depends on a conscience of patients, members of their families, nurses and doctors.
