Karyorrhexis

Karyorrhexis (from Greek κάρυον karyon 'kernel, seed, nucleus' and ῥῆξις rhexis 'bursting') is the destructive fragmentation of the nucleus of a dying cell^[1] whereby its chromatin is distributed irregularly throughout the cytoplasm.^[2] It is usually preceded by pyknosis and can occur as a result of either programmed cell death (apoptosis), cellular senescence, or necrosis.
