Unbalanced jumping translocation involving 3q in myeloproliferative disease

An 87-year-old woman was diagnosed with unclassified myeloproliferative disease having an acquired jumping translocation with the long arm of chromosome 3 translocating to the short arm telomeric region of chromosome 8 (major clone) and the long arm telomeric region of chromosome 10 (minor clone). Each abnormal clone was also associated with an extra copy of chromosome 8. Although there was no evidence of transformation to an acute leukemia, the patient deteriorated until her demise 7 months after disease presentation. There have been fewer than 70 cases of acquired jumping translocations reported in the literature. To our knowledge, this is the first acquired jumping translocation case to be reported in a patient with myeloproliferative disease.
