Myelodysplastic syndrome and trisomy 14q

Cancer Genet Cytogenet. 1992 Nov;64(1):91-2. doi: 10.1016/0165-4608(92)90330-b.


Trisomy 14 as a sole karyotypic abnormality in neoplasia is extremely rare. In hematologic disorders, 18 cases have been reported so far, 17 of which involved disorders of the myeloid lineage. Five were cases of myelodysplastic syndrome (MDS), and a further four involved Philadelphia-negative atypical chronic myeloid leukemia. The case presented here is the second case of trisomy 14q in MDS involving the chronic myelomonocytic leukemia subtype. There were certain features in common with some of the previously reported cases. We raise the possibility that this represents a specific entity.
