This pathology atlas consists of 22 CD-ROMS, each dedicated to one organ system. Three have already been prepared, the others are to appear over the next two years. Each CD-ROM is an image database depicting the known lesions of the relevant organ system, backed by a short description of the lesion as well as its international classification. Three types of classification are selectable upon entering the programme: ICD-10, SNOMED, or ADICAP, as is the choice of language, English or French.
