During the 10 years since the last edition of Histopathology of Non-Hodgkin's Lymphomas, based on the updated Kiel classification, our knowledge on malignant lymphomas, especially on extranodal lymphomas, has increased. This volume - Histopathology of Nodal and Extranodal Non-Hodgkin's Lymphomas - is an expanded and completely revised edition, now based on the WHO classification. The parallels to the updated Kiel classification and the REAL classification are indicated. The information is organized in organ-specific chapters, comprising the well-known nodal lymphoma entities as well as all known extranodal lymphomas and the different organ-specific clinico-pathological entities: lymphomas of the spleen, the gastrointestinal tract, the skin, etc. In addition to the morphology, the major immunohistochemical, molecular genetic, and clinical data are included in each chapter.

This pathology atlas on CD-ROM consists of 22 CD-ROMS, each dedicated to one organ system (see list of titles). Three CD-ROMs have already been prepared, the others are scheduled to appear within the next two years. Each CD-ROM is basically an image database depicting the known lesions of a given organ system, a short description of the lesion as well as the international classification of the lesion. Three types of classification are available upon entering the programme: ICD-10, SNOMED, or ADICAP. The programm is in English or French clickable. The authors are soliciting pathologists from countries all over the world to help promote the series.
