Jerzy Klijanienko, MD is Senior Surgical Pathologist and a Clinical Oncologist, as well as Head of Cytopathology, at the Institut Curie in Paris, France. He previously published a large, well-received series of articles concerning cytopathology in soft tissue tumors and has written a best-selling monograph on the pathology and diagnosis of salivary tumors. Réal Lagacé, MD, is Clinical Pathologist at the Hôpital Universitaire in Quebéc, Canada, where he specializes in the study, diagnosis, and treatment of soft tissue tumors. He has a particular interest in the morphology and molecular biology of tumors, and has widely published in these areas.
