title: Mesenchymal hamartoma of the liver originating in the caudate lobe with t(11;19)(q13;q13.4): report of a case.
abstract: We herein report the case of a 35-month-old female child presenting with mesenchymal hamartoma of the liver (MHL), with t(11;19)(q13;q13.4) originating in the caudate lobe. This case is the eighth known description of a cytogenetic abnormality in mesenchymal hamartoma of the liver. It is similar to the seven cases previously reported, in that one of the breakpoints involves the chromosome band 19q13.3 or 19q13.4, but it is the first report of an abnormality originating in the caudate lobe.
