Specific chromosome abnormalities characterize benign and malignant adipose tissue tumors and are of great diagnostic and clinical importance. Lipoblastoma is a rare benign adipose tumor that mimics myxoid liposarcoma histologically. Although only a few lipoblastomas have been investigated cytogenetically, it is increasingly clear that these adipose tissue tumor generally show rearrangements of 8q11-q13 region but lack the t(12;16) that allows these tumors to be distinguished from myxoid liposarcomas.
