The composite lymphoma: chronic lymphocytic leukemia--classic Hodgkin's lymphoma.
The composite lymphoma (CL) is defined by the presence in the same tissue or organ of two distinct histological aspects of non-Hodgkin's lymphoma (NHL), or NHL and Hodgkin's lymphoma (HL). The definition of the CL has evolved, requesting the identification of the immunophenotypic pattern and clonal distinct aspects for the two-lymphoproliferative lesions. We present a case of a 73-year-old farm...
متن کاملHodgkin lymphoma transformation of chronic lymphocytic leukemia/small lymphocytic lymphoma.
Transformation to a large cell lymphoma may occur during the course of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) in approximately 5% of the cases. This is known as Richter's transformation. A much less frequent transformation to Hodgkin lymphoma may occur. We report a case of CLL/SLL in which a transformation to Hodgkin lymphoma occurred, and we review previously publish...
متن کاملLymphoma and Chronic Lymphocytic Leukemias
ABSTR ACT: The survival of patients with chronic lymphocytic leukemia (CLL) has significantly improved in the last 30 years. The introduction of purine analogs in the treatment armamentarium followed by the combination of these compounds with alkylating agents first improved response rates and progression-free survival (PFS) when compared with alkylating agent-based therapy only. However, the g...
متن کاملLymphoma and Chronic Lymphocytic Leukemias
Sporadic Burkitt lymphoma (BL) accounts for 1% to 2% of lymphomas in adults. The abdomen is the most common site of involvement. The 2008 World Health Organization Classification of Tumors of Haematopoietic and Lymphoid Tissues introduced a new category of high-grade B-cell lymphomas: an entity with overlapping features of both diffuse large B-cell lymphoma and Burkitt lymphoma (DLBCL/BL). Thes...
متن کاملHematopathology / BICLONAL CHRONIC LYMPHOCYTIC LEUKEMIA
Chronic lymphocytic leukemia (CLL) is well characterized clinically and immunophenotypically. Demonstration of a monotypic CD19+, CD5+ B-cell population is central to the diagnosis. We report 2 cases of biclonal CLL. Two elderly men were encountered with an absolute lymphocytosis consisting of the typical CD5+, CD19+, CD23+ B-cell population seen in CLL; however, immunoglobulin light chain rest...
