karyolysis
Karyolysis (from Greek κάρυον ''karyon'', "kernel, seed or nucleus", and λύσις ''lysis'' from λύειν ''lyein'', "to separate") is the complete dissolution of the chromatin of a dying cell due to the enzymatic degradation by endonucleases. The whole cell will eventually stain uniformly with eosin after karyolysis. It is usually associated with karyorrhexis and occurs mainly as a result of necrosis, while in apoptosis after karyorrhexis the nucleus usually dissolves into ''apoptotic bodies''.
