description

Abstract Pulmonary chondroid hamartomas (PCH) are benign mesenchymal tumors consisting of at least two cytogenetic subgroups. These subgroups are defined by chromosomal alterations at either 12q14∼q15 or 6p21. Cytogenetic analysis of short-term cultures from two PCHs revealed two different rearrangements with 12q14∼q15. One of these had a unique translocation t(12;14)(q14∼15;q24) with presence of two normal chromosomes 12 and a der(14), but missing the der(12). The other showed a complex rearrangement between chromosomes 10 and 12 with two different derivatives. Our data have been confirmed with fluorescence in situ hybridization analysis. These cases represent variant forms of the standard translocations.
