Patients were staged according to the Ann Arbor system.
Abbreviations: cb, centroblastic; LN, lymph node; BM, bone marrow; CLL, chronic lymphocytic leukemia.
All cases were classified as DLBL in the REAL classification; all cases had a CD20+CD3− B-cell phenotype.
Cases showing variable expression of CD30 after antigen microwave retrieval.
