We analyzed 11 PCHs with a t(3;12)(q27 approximately 28;q14 approximately 15) for the expression of the LPP-HMGA2 fusion transcript.     ///    Expression patterns of the LPP-HMGA2 fusion transcript in pulmonary chondroid hamartomas with t(3;12)(q27 approximately 28;q14 approximately 15)..     ///    q14 approximately 15) in lipomas and pulmonary chondroid hamartomas (PCHs) makes the HMGA2-LPP fusion gene the most frequent fusion gene in human tumors.     ///    "In a previous study, all of these tumors were shown to express the HMGA2-LPP fusion transcript, composed of exons 1-3 of HMGA2 and exons 9-11 of LPP. "    ///    "To our knowledge, this is the first report of the expression of the LPP-HMGA2 fusion transcript in a series of PCHs. "    ///    "In a previous study, all of these tumors were shown to express the HMGA2-LPP fusion transcript, composed of exons 1-3 of HMGA2 and exons 9-11 of LPP."    ///    "Thus, based on this one finding, a role of LPP-HMGA2 in PCH should be considered..
