[Spontaneous radial segmentation of cell nuclei: morphologic marker of T-cell neoplasms?].
Radial segmentation (RS) of leukocyte nuclei has been observed, for example, in leukemias (Rieder cells). In 6 of 8 patients with T-ALL, RS of neoplastic cells was found in the peripheral blood, whereas in 14 patients with non-T-ALL no RS cells were present. RS may be a morphologic marker for certain T-cell neoplasms, and with regard to ultrastructure it seems to be identical to heat-induced RS of non-neoplastic cells.
