To the Editor: Recently, a partial deletion of the long arm of chromosome 16, del(16)(q22), was reported in patients with bone-marrow eosinophilia and acute nonlymphocytic leukemia.1 Le Beau et al.2 subsequently identified an apparently related cytogenetic-clinicopathological correlation: an association of a pericentric inversion of chromosome 16, inv(16)(pl3;q22), with abnormal marrow eosinophils in acute myelomonocytic leukemia (acute nonlymphocytic leukemia subtype M4).3 We have identified acquired structural rearrangements of chromosome 16 in bone-marrow cells from four patients with acute nonlymphocytic leukemia. Three of the patients had an inversion of chromosome 16, inv(16)(pl3q22). The fourth patient had a translocation involving both chromosome 16.
