Malignant melanoma with areas of rhabdomyosarcomatous differentiation arising in a giant congenital nevus with RAF1 gene fusion
4 Apr 2019
Abstract excerpt
A girl, born with a posterior lumbosacral giant congenital nevus, developed a central nodule that expanded over a period of 14 months into a 10-cm pedunculated mass. Histological analysis of the mass revealed melanoma of myxoid, small round-cell type with areas of rhabdomyosarcomatous transformation confirmed by immunohistochemistry. RNA sequencing identified an in-frame SASS6(e14)-RAF1(e8) fusion in both...
