1) 15 y.o. girl with a 6 mm diameter congenital nevus on upper back.  Looks benign to me but has an interesting play of color.

2) 10 y.o. girl with a planaria shaped nevus on the right 4th toe.  Pigment globules likely represent growth.

3) 14 yo girl last seen 10 years ago.  Congenital nevus noted on l. upper back then, 9 mm diameter.  7.28.15 the lesion is 20 mm diameter. It has find terminal hairs.  There are two (?) satellite lesions near to it, the largest being 7 mm diameter.  The new lesion has a peculiar pattern dermatoscopically.  Still, I think it is benign.  I gave them a follow-up for 6 months.
