Myelodysplastic syndrome with trisomy 8 associated with Behçet syndrome: an immunologic link to a karyotypic...

Myelodysplastic syndrome (MDS) in children is often associated with chromosomal anomalies and trisomy 8 is a characteristic karyotypic feature in up to 20% of the cases. Behçet disease is a rare multisystem inflammatory disorder characterized by recurrent mouth and genital ulcers. MDS with trisomy 8 has been observed in adult patients with Behçet syndrome with some cases developing prior to the clinical manifestations of the latter. We present a female with a similar association and explain the importance of identifying the coexisting conditions. The immunological abnormalities, which may be observed in MDS and their possible mechanisms, are also discussed.
