Development of in situ melanoma after allogeneic bone marrow transplantation in Griscelli syndrome type II

Abstract

GS is an uncommon autosomal recessive disorder characterized by pigmentary dilution of the skin and hair and in most patients by abnormal regulation of the immune system. Childhood melanoma is rare in the pediatric population. The best prognosis is achieved with early diagnosis and definitive surgical excision of melanoma. We report a case of a patient with GS type II and melanoma who was successfully treated by allogeneic bone marrow transplantation and surgical excision of the melanoma. © 2007 Blackwell Munksgaard.
