RESUMEN

Among hematologic diseases, structural abnormalities of autosomal chromosomes are well-known, but cases involving the sex chromosomes are uncommon. Duplications of the long arm of chromosome 1 have been reported in several hematologic diseases including myelodysplastic syndrome, myeloproliferative neoplasms, acute myeloid leukemia, acute lymphoblastic leukemia, and Burkitt lymphoma. However, dup(1q) as a der(Y)t(Y;1)(q12;q12) is very rare. Here, we report a case of essential thrombocythemia harboring der(Y)t(Y;1)(q12;q12) with literature review.

RESUMEN

Acquired partial duplication or triplication of the long arm of human chromosome 1 has been observed rarely in myelodysplastic syndrome (MDS). We describe a dup (1)(q21q32), trp (1)(q21q32) in a patient with refractory anemia of MDS. A 51-year-old man was admitted for dyspnea. Five months ago, he was diagnosed with myelodysplastic syndrome (RA) and iron deficiency anemia and had been treated with iron, vitamin B12, oxymetholone, and prednisolone. The karyotype of trypsin-Giemsa-banded metaphase cells obtained from bone marrow aspirates was 46, XY, dup (1)(q21q32)x2[5]/46,XY,trp (1)(q21q32)[2]/46, XY, dup (1)(q21q32), trp (1)(q21q32)[2] and confirmed the amplification of 1q21-1q32 by CGH (comparative genomic hybridization). In this assay, test and reference DNAs are labeled with FITC and Texas Red, respectively and co-hybridized to normal metaphase chromosomes. Ratio profiles of each individual chromosome were analyzed using a Quips-XL software (Vysis, Downers Grove, IL, USA). The thresholds of gain and loss were defined 1.2 and 0.8, respectively.
