A giant pigmented nevus (GPN) was present in only one of identical twins. Proof of the identical twinship was based on blood group and HLA system findings. The time of appearance of GPN malformation is assumed to be during early embryologic life. Despite previous opinions to the contrary, we suggest that there is no genetic transmission in GPN.
