“…In marked contrast to the average counts in people having predominantly white coloring arc the low numbers of nevi per per son in blacks [4,5,7], Mean nevus counts in Negroids ranged from 1.4 to 10.5. Surpris ingly, no published data exist comparing nevus counts between Caucasians and Negroids in one investigation and by the same observer(s).…”

There exists a large body of evidence that the occurrence of nevocytic nevi is closely related to skin complexion. Nevi are more frequent in Caucasians with a light skin than in those with a dark phenotype. In Orientals and Negroids nevocytic nevi are uncommon. Within a black population subjects with a relatively light complexion have greater total counts than those with a very dark skin. It is concluded that literature data dealing with mole proneness in relation to skin complexion strongly point to an association of high nevus counts with light complexion. This applies to differences between racial groups as well as to differences between complexion phenotypes within a given racial group.

In 939 schoolchildren aged 8–16 years skin complexion was determined by a system of seven categories. Anamnestic data concerning tanning ability and history of sunburns, however, were not considered owing to their obvious unreliability in children. Mean nevus count was 17.97 was significantly higher in boys than in girls and increased with age. There was a clear relation of mean nevus number and skin complexion: in fair skin type nevi are most frequent decreasing in number by increasing of pigment content. Additionally, children with freckles have higher mean nevus count in every category of skin complexion. All literature data critically reviewed as dealing with mean mole count are not comparable in several respects. In different races however such studies may serve as a basis for subsequent investigations concerning the questions of probably increasing number of melanonevocytic nevi.

“…It may be that these children are ultimately at risk of melanomas arising in idiopathic acral naevi. The relationship between acral-lentiginous melanoma and acral naevi has been studied in Ugandan Africans, but no direct association was observed (Lewis, 1968). However in view of the consistency in two analytic studies of an apparent excess of acral naevi in childhood cancer survivors, it may be appropriate to alert these patients to the significance in later life of any changes in plantar moles, since acral-lentiginous melanomas often have a poor prognosis due to late diagnosis.…”
