L. Jeffrey Medeiros MD is Professor and Chair at the Department of Hematopathology of the University of Texas MD Anderson Cancer Center in Houston, Texas. His research interests include the diagnosis of lymphomas, including the use of histologic, imunnophenotypic, and molecular methods for diagnosis and prognosis, and most recent research efforts have focused on diffuse aggressive B-cell lymphomas. Dr. Medeiros is the returning co-lead author of Diagnostic Pathology: Lymph Nodes and Extranodal Lymphomas. Roberto N. Miranda, MD is a Professor at the Department of Hematopathology at the University of Texas MD Anderson Cancer Center in Houston, Texas. His research interests include T-cell lymphomas and he has developed an expertise in breast implant-associated anaplastic large cell lymphoma, a topic on which he has several landmark publications and book chapters, and on which he has lectured nationally and internationally. Dr. Miranda is the returning co-lead author of Diagnostic Pathology: Lymph Nodes and Extranodal Lymphomas.

"This book is part of the Diagnostic Pathology Series, covering benign and malignant lesions of lymph nodes, as well as extranodal lymphomas. This third edition has been updated from the previous version, published in 2017, according to the most recent fifth edition of the WHO Classification of Hematolymphoid Tumors." -©Doody’s Review Service, 2023 Anamarija Perry, MD (University of Michigan Medical School) Doody's Score: 5 Stars!
