Molecular cytogenetic study of a hemangiopericytoma in a newborn.

Abstract Two balanced reciprocal chromosome translocations, t(8;12)(p21;p13.1) and t(15;16)(q24;q22), characterized a rare hemangiopericytoma in a newborn. Chromosome painting with a chromosome microdissection-derived whole-chromosome 8 probe confirmed that the t(8;12) was due to a reciprocal translocation. To the best of our knowledge, these chromosome findings are unique to this unusual case of a pediatric hemangiopericytoma.
