During his presentation at the NCCN 19th Annual Conference, Dr. Andrew D. Zelenetz reviewed the updates to the 2014 NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Non-Hodgkin’s Lymphomas. Dr. Zelenetz first discussed the updates for diffuse large B-cell lymphoma (DLBCL), focusing primarily on the emergence of MYC-positive DLBCL; the limited role of imaging in early-stage disease; new treatment options; the challenge of tumor heterogeneity; and the impact of cell of origin in the selection of future therapies. Then, on behalf of Dr. Steven Horwitz, Dr. Zelenetz presented the new guidelines for primary cutaneous CD30+ T-cell lymphoproliferative disorders and T-cell large granular lymphocytic leukemia.

Abstract Background Lymphocytic neoplasms with frequent reactive lymphocytes are uncommonly reported in dogs, and can pose a diagnostic challenge. Different diagnostic modalities such as cytology, flow cytometry, histopathology, immunohistochemistry, and clonality testing, are sometimes required for a diagnosis. This report illustrates the value of using a multi-modal diagnostic approach to decipher a complex lymphocytic tumor, and introduces immune repertoire sequencing as a diagnostic adjunct. Case presentation A 10-month-old Great Dane was referred for marked ascites. Cytologic analysis of abdominal fluid and hepatic aspirates revealed a mixed lymphocyte population including numerous large lymphocytes, yielding a diagnosis of lymphoma. Flow cytometrically, abdominal fluid lymphocytes were highly positive for CD4, CD5, CD18, CD45, and MHC II, consistent with T cell lymphoma. Due to a rapidly deteriorating clinical condition, the dog was euthanized. Post mortem histologic evaluation showed effacement of the liver by aggregates of B cells surrounded by T cells, suggestive of hepatic T cell-rich large B cell lymphoma. Immune repertoire sequencing confirmed the presence of clonal B cells in the liver but not the abdominal fluid, whereas reactive T cells with shared, polyclonal immune repertoires were found in both locations. Conclusions T cell-rich large B cell lymphoma is a rare neoplasm in dogs that may be challenging to diagnose and classify due to mixed lymphocyte populations. In this case, the results of histopathology, immunohistochemistry and immune repertoire sequencing were most consistent with a hepatic B cell neoplasm and reactive T cells exfoliating into the abdominal fluid. Immune repertoire sequencing was helpful in delineating neoplastic from reactive lymphocytes and characterizing repertoire overlap in both compartments. The potential pitfalls of equating atypical cytomorphology and monotypic marker expression in neoplasia are highlighted.

In this report, we describe a 38-year-old male with a very rare type of lymphoma, large B cell lymphoma with T cell-rich background and nodules lacking follicular dendritic cell meshworks (THRLBCL). In 2016 the patient presented hot flashes and night sweats (B-symptoms) and peripheral edema. He was treated with R-CHOP (doxorubicin, vincristine, cyclophosphamide, rituximab and Prednisone) chemotherapy, a Positron emission tomography–computed tomography (PET-CT) scan was performed after four cycles of treatment which showed radiologic complete response and blood test (complete blood count (CBC)) results showed normal ranges. As of September, 2020 he patient remains in complete remission. We searched the literature for descriptions of cases spanning the diagnostic spectrum of THRLBCL and we identified only five cases worldwide. The last reported case was in 2014 with distinctive features that were difficult to classify according to the World Health Organization criteria or previously described variants. Our patient is the sixth case of THRLBCL to be reported. He is the youngest of the reported cases and the first from Israel and the Middle East.
