title: Pediatric orbital hemangiopericytoma associated with trisomy 15.
abstract: We report a case of an orbital hemangiopericytoma (HPC) in a female infant diagnosed at 7 weeks of age. Cytogenetic analysis of the tumor revealed trisomy 15. To the authors' knowledge, this is only the second reported case of this chromosomal aberration being associated with HPC, both cases occurring in infants.
