T-cell leukemia-lymphoma and mycosis fungoides.

Notable efforts have been made to relate aspects of the cell biology of T cells to the pathology, diagnosis, and treatment T-cell neoplasms. In particular, the application of molecular biologic tools to these areas has already allowed the generation of patient-specific markers for disease. A case can be made that a knowledge of the distinctive natural history of T-cell neoplasms should influence choices of treatment. Additional insights into the relevance of the human T-cell leukemia-lymphoma virus family to human disease have been recorded, and an important association of cutaneous T-cell lymphoproliferative disorders with human immunodeficiency virus infection has been documented.
