Abstract

We report a case of a female karyotype that was normal except for double minutes (dmin) in acute myeloid leukemia. Using fluorescence in situ hybridization, the amplification of C-MYC was detected in both interphase and metaphase cells. The patient of the present case had received only limited therapy with cytosine arabinoside, but lived for more than one year. It supports the recent notion that dmin may not necessarily be associated with a poor outcome.
