History
A 13-year-old red hair, fair-skinned boy was referred to our
clinic for evaluation of a large congenital pigmented lesion on his
left leg. The lesion had gradually enlarged, and over the last 4
years several reddish, itching nodules had developed within it. In
addition, he had a 2-year history of myelodysplastic syndrome,
controlled with ciclosporin A (40 mg/day). There was no family
history of pigmented disorders.
