Editor of this issue, Dr Anil Parwani, is Professor of Pathology and Biomedical Informatics and Director of Division of Pathology Informatics. Dr. Parwani is well known as expert in the area of Anatomical Pathology Informatics, which includes design of quality assurance tools, tissue banking informatics, clinical and research data integration and mining, synoptic reporting in anatomical pathology, clinical applications of whole slide imaging, digital imaging, telepathology, image analysis and lab automation and workflow processes, such as barcoding and voice recognition.

This issue will focus on the global state of hematology and will include articles such as: The Global Burden of Anemia, Iron Deficiency Anemia: Problems in Diagnosis and Therapy, Progress Towards the Control and Management of the Thalassemias, Problems and Approaches for Blood Transfusion in the Developing Countries, and many more!

Dr. George Fedoriw leads the second issue presented in the Surgical Pathology Clinics on Hematopathology. Topics in this issue include: Evidence-based, high-value hematopathology; The expanding spectrum of follicular lymphoma; Lymphoid proliferations in the immunocompromised host; Reporting clinically relevant biomarkers of intermediate/high grade B-cell lymphomas; Transformation of lymphomas; T-cell lymphoproliferations: distinguishing benign from malignant; Lymphoma microenvironment and immunotherapy; Differentiating low grade lymphomas with non-specific immunophenotype; Molecular markers of myeloid leukemias and myelodysplastic syndromes; Update of myeloproliferative neoplasms; Mimics of myeloid neoplasms; Therapy effect: impact on bone marrow morphology. Each topic is written by a leader in pathology with expertise in hematopathology. The focus on these articles, as all in the series, is on Differential Diagnosis, with histologic images and tips for working with the most challenging aspects of these pathologies.
