Hyperdiploidy and trisomy 12 in the cystic partially differentiated nephroblastoma.

The karyotype of a cystic partially differentiated nephroblastoma (CPDN) was found to be 51, XY, +7, +8, +12, +13, +17. A review of the literature disclosed three other cytogenetically analyzed CPDNs. As in this case, they were all hyperdiploid. The only chromosomal anomaly common to all four cases was trisomy 12, suggesting this chromosome might have a pathogenetic role. Earlier reports had tentatively attributed this role to chromosome 8.

Cytogenetic analysis of a choroid plexus papilloma.

We report the cytogenetic analysis of a choroid plexus papilloma, a benign tumor, with a modal number of 56 chromosomes. In our review of the few reported karyotypes of choroid plexus tumors, we found no predictive relationship between the karyotype and the pathologic diagnosis or outcome.

Consistency of isochromosome 7q and trisomy 8 in hepatosplenic gammadelta T-cell lymphoma: detection by fluorescence In situ hybridization of a splenic touch-preparation from a pediatric patient.

Hepatosplenic gamma-delta (gammadelta) T-cell lymphoma is a rare but increasingly recognized lymphoid malignancy predominantly affecting young adult males. It is not well appreciated in the pediatric population. We report the third case of this aggressive lymphoma in a child as well as additional support for the consistency of the recently discovered cytogenetic abnormalities, isochromosome 7q and trisomy 8, which in this case were documented using fluorescence in situ hybridization (FISH) of a touch-preparation of the spleen.
