In 1948 Dr Sophie Spitz described criteria that distinguished juvenile
melanoma from malignant melanoma.(1) Since then the cases of eruptive
Spitz naevi have been reported arising on normal skin, on lightly pig
mented patches and on hypopigmented patches. There are only 12 reports
of Spitz naevi arising on hyperpigmented patches:(2-12) we describe h
ere three further cases, all on the arms of children, seen in our depa
rtment in a single year.
