SUMMARY The cases of two young adults with widespread multiple eruptive naevi are described. In the first patient, more than 100 lesions appeared during a period of 6 months. Young lesions were small fleshcoloured telangiectatic papules; older lesions were larger and verrucose with histological features of cellular naevi. In the second patient, a great number of lentigines developed in the course of 2 years. Light and electron microscopy showed that giant melanosomes were present within the lesions. The plasma level of β‐MSH‐like immuno‐reactivity was normal.
