A high frequency of tumors with rearrangements of genes of the HMGI(Y) family in a series of 191 pulmonary chondroid hamartomas.

Pulmonary chondroid hamartomas (PCHs) are benign mesenchymal tumors that often are characterized by specific chromosomal aberrations. Herein we report our cytogenetic and molecular cytogenetic (FISH) studies on 191 PCHs, including 48 previously published cases. In this series, 134/191 PCHs (70.
