The authors of this volume have put emphasis on diagnosis, so the presentation is generally concise, yet more comprehensive on key points. In addition, they emphasise diagnostically-important information on immunohistochemistry and molecular genetics, and include additional details when biologically significant. Site-specific soft tissue entities covered in the other atlases are often excluded due to space constraints.The text is aimed as a practical diagnostic aid for pathologists, cytopathologists and pathology trainees, but the authors hope that their clinical colleagues and others may also find it as a useful source of information on soft tissue tumours and tumour-like lesions.
