title: [Naevus pigmentosus and melanoma].
abstract: Clinical observations and histological findings support the relationship between pigmented naevi and melanoma. The author describes the morphological characteristics of congenital, acquired and atypical naevi in relation to the appearance of melanoma. On the basis of clinical observations, in harmony with other investigators, the author advises patients to perform self examination and to undergo regular survey of numerous atypical naevi by a dermatologist. In fact, any of the atypical pigmented naevi present in high number may be a precursor lesion. Patients with such lesions are at higher risk of melanoma development.
