Many infectious agents disseminate in blood and the lymphatic system, and many of these infections are also tropical diseases that affect a large segment of the world's population, including travelers, immigrants, and refugees. The authors have carefully incorporated in this new book those diseases found in both Western and Eastern hemispheres, in order to assist pathologists and medical laboratory professionals all over the world to better diagnose and treat infections that may be expected, or indeed quite unusual for a given geographic region. The book features a wide range of non-neoplastic hematologic disorders, as well as reactive patterns of non-infectious and infectious agents, all thoroughly illustrated with photographs, tables and text. In addition to the comprehensive and state-of-the-art diagnostic materials, the epidemiology, pathobiology, clinical and pathologic manifestations in blood and lymphatic organs, as well as approaches to treatment, are also described.

Hernani Cualing MD, is Associate Professor in the Department of Pathology and Cell Biology and Director of the Hematopathology Fellowship Training Program at the University of South Florida College of Medicine in Tampa, Florida. He is also an active hematopathologist at the Moffitt Cancer Center and Research Institute there. In addition to his research into such topics as mantle cell and T cell lymphomas, Dr. Cualing has long been fascinated with the analysis, diagnosis, and treatment of non-neoplastic and infectious blood, marrow, and lymph diseases.

Parul Bhargava, MD, is Medical Director in the Hematology Laboratory at Beth Israel Deaconess Medical Center-Needham Campus in Boston, and a staff and faculty physician in the Pathology department there. Her primary research interests are in studying hematopoietic neoplasms and newer markers in Hodgkin Lymphoma, but she also has a strong, separate clinical interest in studying the effects of immunodeficiency and infections, particularly HIV, on the hematopoietic system.

Ramon L. Sandin, MD, MS, FCAP, ABP-MM, is a Clinical Pathologist and Medical Director of Clinical Microbiology and Virology in the Department of Hematopathology, Laboratory Medicine, and in the Blood and Marrow Transplant Program at the Moffitt Cancer Center in Tampa, Florida 33612-9497. His special areas of expertise and research interests are in clinical microbiology and virology, and laboratory diagnosis of infectious diseases. This includes 'wet' laboratory work-ups and tissue section diagnosis as well as molecular diagnostic techniques.
