Since 1980, manyhospital information systems (HIS) cameintobeing. These HISareattheorigin of thestorage ofhugemedical data. Datamining isa domain which presents themostpowerful tools forthe extraction ofknowledge andforstructuring them. The first intelligent systems or assistance systems for medical diagnosis arethecase-base reasoning systems. In thesesystems, thedataminingmethodwas integrated toimprove themandtofill somegaps. Wepresent anapplication ofdatamining which isbasedoncase-base reasoning. Thecharacteristic of thisapplication isbuilding knowledge basewithout integrating expertknowledge and we use this knowledge basetoretrieve case fromcasebase.
