CD20-Negative Nodular Lymphocyte-Predominant Hodgkin Lymphoma: A 20-Year Consecutive Case Series From a Tertiary Cancer Center.
Archives of pathology & laboratory medicine
2020
Abstract
Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare, indolent Hodgkin lymphoma subtype with distinct clinicopathologic features and treatment paradigms. The neoplastic lymphocyte-predominant cells typically express bright CD20 and other B-cell antigens, which distinguishes them from Hodgkin/Reed-Sternberg cells of lymphocyte-rich classic Hodgkin lymphoma.To characterize the clinicopathologic features of CD20-negative NLPHL at a single institution.A retrospective search for CD20-negative NLPHL in our pathology archives and medical records was conducted.Of 486 NLPHL patients identified with CD20 available for review, 14 (2.8%) had LP cells with absent CD20 expression. Patients with prior rituximab administration (n = 7) and insufficient clinical history (n = 1) were excluded, leaving 6 patients with rituximab-naïve, CD20-negative NLPHL. A broad immunohistochemical panel showed the LP cells in all cases expressed B-cell antigens, particularly Oct-2, although PAX5 and CD79a were frequently also dim. CD30, CD15, and Epstein-Barr virus-encoded small RNAs were negative in all evaluated cases. Two patients had high-risk variant immunoarchitectural pattern D. One patient had extranodal disease, involving the spleen and bone, and was suspected to have large cell transformation. Standard NLPHL therapy was given, including local radiation and/or chemotherapy. Of 5 patients with available follow-up, 4 are alive in complete remission after therapy, and 1 is alive with relapsed disease.NLPHL can lack CD20 de novo without prior rituximab therapy. In such cases, extensive immunophenotyping helps distinguish NLPHL from lymphocyte-rich classic Hodgkin lymphoma, which differ in clinical behavior and therapy. In our series, CD20-negative NLPHL showed both classic and variant histologic patterns and the expected range of clinical behavior seen in NLPHL, including 1 case with suspected large cell transformation.

Complexities in the diagnosis of large B-cell lymphomas, classic Hodgkin lymphomas and overlapping peripheral T-cell lymphomas simplified: An evidence-based guide.
Annals of diagnostic pathology
2020; 46: 151534
Abstract
The diagnosis of a large B-cell lymphoma and classic Hodgkin lymphoma (CHL) is often straightforward. However, in select circumstances, these simple diagnoses can be quite complex. In part, diagnostic difficulty may be due to uncertainty in the evaluation of morphologic and immunophenotypic features along a biologic continuum, or alternatively arise from uncertainty in predicting the behavior and outcomes of patients. Here, we systematically discuss and review areas of diagnostic difficulty in the diagnosis of large B-cell lymphomas (LBCL), classic Hodgkin lymphomas (CHL) and peripheral T-cell lymphomas (PTCL). We provide careful data-driven analyses and evidence-based approaches to help guide pathologists and clinicians. We discuss: 1) marginal zone lymphomas with increased large cells versus diffuse large B-cell lymphoma (DLBCL), 2) chronic lymphocytic leukemia with expanded proliferation centers versus diffuse large B-cell lymphoma (DLBCL), 3) chronic lymphocytic leukemia with Hodgkin/Reed-Sternberg-like cells versus CHL arising from chronic lymphocytic leukemia, 4) complex cases of follicular lymphoma versus DLBCL, 5) PTCL with large B-cell proliferations versus PTCL with LBCL, 6) PTCL with Hodgkin/Reed-Sternberg-like cells versus CHL, and finally 7) blastoid/pleomorphic mantle cell lymphoma versus DLBCL. Our evidence and data driven approach may serve as a useful diagnostic guide.

Histiocytic Sarcoma Associated With Follicular Lymphoma: Evidence for Dramatic Response With Rituximab and Bendamustine Alone and a Review of the Literature.
Clinical lymphoma, myeloma & leukemia
2018
Abstract
Histiocytic sarcoma (HS) is a rare aggressive malignancy with a dismal prognosis and no agreed-upon standard treatment. Classically, the diagnosis of HS has been difficult to confirm and has relied on inaccurate, crude techniques. Therapy often involves intensive chemotherapeutic regimens, surgery, and/or radiotherapy, which are poorly tolerated with variable response rates. Patients often die of diffusely metastatic disease. Modern diagnostic techniques are helping to slowly uncover more uniquely customized therapeutic approaches in this enigmatic disease. We present a review of the current literature regarding HS diagnosis, treatment, and outcomes. Additionally, we describe the first reported case of HS transdifferentiated from follicular lymphoma that had a dramatic and durable response to rituximab/bendamustine alone as initial treatment. Unlike traditional chemotherapy regimens, this treatment was well tolerated and had a good toxicity profile. The combination of rituximab and bendamustine warrants further investigation in the treatment of HS, especially those originating from prior follicular lymphoma. Modern immunohistochemical and molecular profiling techniques are beginning to reveal heterogeneity among HS tumors and potentially therapeutic targets.

Prostate-Specific Membrane Antigen-Targeted Imaging With [18F]DCFPyL in High-Grade Gliomas.
Clinical nuclear medicine
2017; 42 (10): e433-e435
Abstract
High-grade gliomas (World Health Organization grade III-IV) are highly lethal primary brain tumors. Imaging modalities, including MRI and FDG PET, provide a limited ability to differentiate treatment effects (such as radiation necrosis) from recurrent or residual tumor. As the first step in validating the applicability of prostate-specific membrane antigen (PSMA)-targeted imaging in high-grade gliomas, we evaluated the ability of the PSMA-targeted small molecule [F]DCFPyL (2-(3-(1carboxy-5-(6-[F]fluoro-pyridine-3-carbonyl)-amino]-pentyl)-ureido)-pentanedioic acid) to image high-grade gliomas in a series of 3 prospectively recruited patients. We found [F]DCFPyL binds PSMA in the neovasculature of glioblastoma multiforme and tumor cells of anaplastic astrocytoma.

Mantle cell lymphoma with a novel t(11;12)(q13;p11.2): a proposed alternative mechanism of CCND1 up-regulation.
Human pathology
2017; 64: 207–12
Abstract
Mantle cell lymphoma (MCL) is typically characterized by t(11;14), which places the IGH@ enhancer elements upstream of CCND1. This fusion results in up-regulation of CCND1 and consequently its protein product cyclin D1. Recent studies have shown that in MCL, mutations or translocations occurring within the 3' untranslated region (UTR) of the CCND1 gene can result in a truncated mRNA transcript that is more stable and associated with more aggressive disease. We identified a case of MCL showing cyclin D1 overexpression by immunohistochemistry and a t(11;12)(q13;p11.2) by conventional cytogenetic studies. Next-generation genomic sequencing indicated a chromosomal break through the CCND1 3'-UTR and fusion with a non-coding region of chromosome 12. We suggest that, in the absence of the typical CCND1/IGH@ fusion, this rearrangement promotes MCL pathogenesis by eliminating miRNA interaction elements within the 3'-UTR of the CCND1 mRNA transcript consequently resulting in CCND1 overexpression.

Evidence that incidental Lewy body disease is pre-symptomatic Parkinson's disease.
Acta neuropathologica
2008; 115 (4): 437-44
Abstract
Lewy bodies, the histologic hallmark of Parkinson's disease (PD), are detected in the brains of about 10% of clinically normal people over the age of 60 years. When Lewy bodies are found in normal individuals, the process is sometimes referred to as incidental Lewy body disease (iLBD). The distribution of Lewy bodies in iLBD is similar to the distribution in PD, but neuronal populations vulnerable to Lewy bodies do not show significant neuronal loss in iLBD. It remains unknown if Lewy bodies in this setting represent pre-symptomatic PD or an age-related change unrelated to PD. To address this question we identified cases of iLBD and used a marker for dopaminergic and noradrenergic neurons, tyrosine hydroxylase (TH), to determine if there were changes similar to those found in PD. TH immunoreactivity in the striatum and the epicardial nerve fibers was decreased in iLBD compared to normal controls, but not to the same extent as in PD. The findings suggest that iLBD is preclinical PD and that the lack of symptoms is due to subthreshold pathology.
