"Lennert's lymphoma" with transformation to malignant lymphoma, histiocytic type (immunoblastic sarcoma). 1977

M A Klein, and R Jaffe, and R S Neiman

Two cases of a recently described lymphoproliferative disorder called "Lennert's lymphoma" are presented. In both cases, the proliferation evolved into a frank malignant lymphoma of large lymphoid cells. This phenomenon has not been previously reported to occur in this disease. Immunohistologic study of the biopsy material in both cases suggest that it may be a T-cell proliferation. The possibility that "Lennert's lymphoma" is not a neoplasm but an abnormal immune reaction with similarities to angioimmunoblastic lymphadenopathy is raised. Whatever its nature, the potential for "Lennert's lymphoma" to transform into a frankly malignant tumor is documented.

UI	MeSH Term	Description	Entries
D007136	Immunoglobulins	Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.

D016403	Lymphoma, Large B-Cell, Diffuse	Malignant lymphoma composed of large B lymphoid cells whose nuclear size can exceed normal macrophage nuclei, or more than twice the size of a normal lymphocyte. The pattern is predominantly diffuse. Most of these lymphomas represent the malignant counterpart of B-lymphocytes at midstage in the process of differentiation.
