Cytogenetic abnormalities can be detected in approximately 50-60% of newly diagnosed adult patients with acute myeloid leukaemia (AML). Monosomy of the chromosome 7 (-7) and deletion of the long arm of the chromosome 7 (7q-) are considered as high cytogenetic-risk AML with a poor prognosis. These abnormalities can occur, as a single chromosomal aberration, in approximately 8% of newly diagnosed AML. We report an elderly patient with AML who had deletion 7q (7q-) along with ring chromosome, which was demonstrated in conventional cytogenetics and fluoresecent in-situ hybridisation techniques.
