Clinics and Pathology

Disease

Myelodysplastic syndrome and non Hodgkin lymphoma.

Epidemiology

Four cases are available to date: an indolent B-cell follicular lymphoma, a non Hodgkin lymphoma (NHL) not otherwise specified (NOS), a refractory anemia (RA) possibly related to the treatment of a multiple myeloma diagnosed 4 years before, and a refractory anemia with excess of blasts in transformation (RAEB-t) evolving rapidly towards an acute myeloid leukemia (AML). There were 2 male and 2 female patients, aged 70, 70, 76 and ? (Fan et al., 1988; Avanzi et al., 1989; Fan and Rizkalla, 2003; Adeyinka et al., 2007).

Prognosis

Data on (short term) evolution is only available in the two myeloid cases: the RA case remained well 4 months after diagnosis, while the RAEB-t/AML case died shortly after diagnosis.

Genes Involved and Proteins

Note
Genes involved in this structural anomaly are unknown.

Summary

Note

The anomaly is found in heterogeneous diseases, but the cases present some surprisingly similar cytogenetic features.
