Abstract

The data on melanoma associaed with melanocytic nevus are controversial. A longitudinal prospective study of 107 cases of cutaneous melanoma revealed that 9 (8.4%) cases were presumed to be linked to a precursor lesion, but only in 1 (0.9%) out of these cases the histopathological examination showed an associated melanocytic nevus. The vague information of a preexisting lesion of cutaneous melanoma is not sufficient to consider it a tumour precursor and it requires histopathological evidence to confirm the diagnosis.Os dados sobre risco de melanoma cutâneo nos nevos melanocíticos são ainda controversos. O estudo longitudinal prospectivo de 107 casos de melanoma cutâneo revelou que em 9/107 casos (8,4%) houve presunção de lesão precursora, porém em 1/107 caso (0,9%) houve comprovação histopatológica para nevo melanocítico. A informação vaga de presença de lesão precursora do melanoma cutâneo torna vulnerável sua vinculação com o tumor e implica em comprovação histopatológica.
