Pathology Data Procrssing for Statistical Analysis System (PADASAS) to be operated in interactive dialogue with the computer was developed by the modification of the previous PADAMS. It serves to figure out characteristics of a disease and to find statistical correlation of lesions in various organs. Always led by the system message, pathologists can use the system as diagnostic aid without knowledge for computer technology. PADASAS has been tested on some 300 autopsy cases and it was found to worl\k well without problem. However, storage of more data is needed to draw statistically significant conclusions which are of value in practice.
