A 70-year-old man with B-cell chronic lymphocytic leukemia (CLL) received single-agent treatment with the purine analogue fludarabine, which led to complete remission. After 8 years, he presented with pancytopenia. ⋯ No residual CLL was present. Together with previous reports of secondary cancers after fludarabine treatment and the association of monosomy 7/7q- with another purine analogue azathioprine, results suggest that t-AML might develop after fludarabine therapy.

May-Hegglin anomaly (MHA) is a rare type of autosomal dominant platelet disorder associated with mutations in the gene encoding nonmuscle myosin heavy chain 9 (MYH9). It is characterized by the presence of large platelets, leukocyte inclusions, and thrombocytopenia. The bleeding tendency is usually mild, but severe hemorrhages have been reported. ⋯ The patient was administered desmopressin (DDAVP) prior to the neurosurgical procedure and had no complications. With this approach, the use of platelet concentrates could be avoided. We discuss the role of DDAVP in MHA and related platelet disorders and review the current literature.
