What is Well-Differentiated Lymphocytic Lymphoma?

A low-grade malignant lymphoma that may, in some cases, be considered histologically identical to chronic lymphocytic leukemia (CLL; LEUKEMIA, LYMPHOCYTIC, CHRONIC). It is diffuse in pattern, representing the neoplastic proliferation of well-differentiated B-lymphocytes. In patients with immunoglobulin gammopathies, the lymphocytes may exhibit plasmacytoid characteristics.
