CD4 and B-cell chronic lymphocytic leukemia: Although B-cell lymphomas with T-cell markers other than CD5, such as CD8+ CLL [5–13] or CD2/CD3/CD4/CD7/CD8+ large B-cell lymphoma [13–31] have been reported (Table 1), data regarding their frequency, histopathological distribution, and clinical features are rarely available, because the number of identified cases in each report is small.
