Hepatic mesenchymal hamartoma with translocation involving chromosome band 19q13.4: a recurrent abnormality

We report a case of mesenchymal hamartoma of the liver in an 8-month-old male child, in which the cytogenetic analysis revealed a balanced translocation, t(11;19)(q13;q13.4). This is the fifth description of a cytogenetic abnormality in mesenchymal hamartoma and is similar to the four cases reported previously in that one of the breakpoints involved chromosome band 19q13.4.
