Lymphoid Malignancies of T-cell Phenotype represent approximately 20% of all lymphoid malignancies. These malignancies are extremely heterogeneous in terms of pathologic and clinical diversity, which traditionally has been a major obstacle in formulating clinically and pathologically reproducible classification. Certain types of these lymphomas have a unique geographic distribution and confirmed association with chronic immunologic and/or antigenic challenges. Although treatment approaches are well defined for some of these lymphomas, the optimal treatment strategies are less well defined for a significant proportion of these malignancies.

The published literature about T-cell lymphomas is relatively limited when compared to lymphoid neoplasia of B-cell phenotype. This Special Issue aims to collate scientific and clinical contributions from experts in the corresponding fields of the different sub-types of T-cell lymphomas. Original research and review articles are welcome.

Potential topics include but are not limited to the following:

• Pathology of T-cell lymphomas
• Classification of T-cell lymphomas
• Clinical research studies
• Translational research studies
• Research related to the unique geographic distribution of these malignancies
• Role of chronic immunologic challenge from viral and other antigens in the pathology of certain sub-types
• Chemotherapy treatment
• Targeted therapy including monoclonal antibodies and molecular therapy
• The role of different types of hematopoietic stem cell transplantation
