Cytogenetic studies of a series of 43 consecutive secondary myelodysplastic syndromes/acute myeloid leukemias: conventional cytogenetics, FISH, and multiplex FISH.

We report a series of 43 consecutive therapy-related myelodysplastic syndromes (t-MDS) or acute myeloid leukemias (t-AML) observed for 6 years. This series consisted of 26 women and 17 men, ages ranging from 9 to 85 years. These cases were classified into three groups according to the primary diagnosis.

[An unusual cause of pancytopenia: intravascular lymphoma].

We report an observation of intravascular lymphoma occurring in a 69-year-old woman. This relatively rare disease presents polymorphic clinical features that render diagnosis difficult. Cutaneous and central nervous system signs and symptoms are frequently observed and should be recognized as suggestive of intravascular lymphoma.
