Evidence for the polyclonal nature of focal nodular hyperplasia of the liver by the study of X-chromosome inactivation
1 Oct 1997
Abstract excerpt
Focal nodular hyperplasia (FNH) of the liver is a benign tumor commonly considered as a reactive disorder related to a pre-existing vascular malformation. However, the pathogenesis of this lesion has been recently discussed. To determine whether FNH is a polyclonal or a clonal lesion, we investigated the inactivation pattern of the X chromosome, using molecular genetic analysis of the DNA methylation pattern at a...
