Trisomy 13 in a case of myelofibrosis with myeloid metaplasia with early blastic transformation

Abstract

We describe a case of early myeloid blastic transformation in a 64-year-old man suffering from myelofibrosis with myeloid metaplasia. Both chronic and blastic phase cytogenetic analysis showed trisomy 13 to be the sole chromosome aberration. A potential role for this rare abnormality in determining such an unusually poor clinical outcome is discussed.
