Introduction Sarcoidosis is a systemic granulomatous disease of unknown etiology characterized by the chronic inflammation. Mucosa associated lymphoid tissue (MALT) lymphoma is a low-grade marginal zone B-cell lymphoma of MALT often etiologically associated with chronic inflammation in the underlying organ. A rare association between sarcoidosis and MALT lymphoma has been reported. Case Description We present the case of a 75-year-old woman who presented with chronic cough and dyspnea of several years' duration. She was found to have fluctuating lung infiltrates on serial imaging studies. A bronchial biopsy revealed chronic inflammation, and no evidence of infection. She was then treated with oral steroids with a transient benefit. However, the infiltrate and symptoms recurred, therefore 8 months later, she underwent repeat imaging. This showed a relapse of the infiltrate and enlarged mediastinal lymphadenopathy. The lung infiltrate was biopsied (percutaneously). This demonstrated a MALT lymphoma. Imaging studies done for staging showed a large retroperitoneal lymph node. A biopsy of this node revealed non-caseating granulomas, consistent with sarcoidosis. Chemotherapy with bendamustine and rituximab was initiated for therapy of the MALT lymphoma. Discussion A rare association between pulmonary MALT lymphoma and underlying inflammation caused by sarcoidosis has been previously described. In our patient, sarcoidosis was diagnosed in a biopsy of a retroperitoneal lymph node, but we suspect that there is likely involvement of the mediastinal nodes.

Abstract Background Pulmonary marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue type (MALT) is recognized as the most common type of primary pulmonary lymphomas. However, due to its relatively-low proportion, the studies focused on this patient population were limited. We aimed to reveal the status of surgery and radiotherapy in survival of pulmonary MALT lymphoma patients. Methods A retrospective analysis was conducted on patients who were pathologically diagnosed as pulmonary MALT lymphoma between 1992 and 2013. Their treatment information was collected in Surveillance, Epidemiology, and End Results (SEER) database. According to the different treatments, they were divided into four groups: Both Surgery and Radiation(SR), Surgery(S), Radiation(R) and No Surgery Or Radiation(NSR). The further subgroup analyses were performed according to age of onset and clinical stages. Overall survival (OS) was calculated from diagnosis up to the date of death or the last follow-up of each patient. Survival curves constructed by the Kaplan-Meier method and log-rank test were utilized for comparison. Results There were 860 pulmonary MALT lymphoma patients were enrolled. The median OS was 55.0 months (0-256.0 months). The OS between patients who underwent surgery and/or radiotherapy(S/R/SR) or not(NSR)(473 VS 387) had shown a significant difference of each other(P < 0.0001), so did the comparison among the four subgroups(SR VS S VS R VS NSR, P < 0.0001). Although there wasn’t any statistical difference in the OS between SR and S groups (P = 0.1174), further analysis on the causes of death revealed that, additional radiation therapy may lead to good short-term efficacy, while elevated mortality associated with long-term pulmonary complications was noteworthy. In the subgroup analyses, patients in stage I-II and over 60 years old shared similar trends with total population involved in the study(P = 0.0001;P < 0.0001). Conclusions The present study confirmed the value of surgery and the possible effects of radiotherapy among patients with pulmonary MALT lymphoma by clinical data from a large number of samples. If the improved radiotherapy regimens are chosen or the pulmonary complications caused by radiotherapy are well-managed, chances will be high that extra benefits could be achieved by combining radiotherapy with the surgical-based therapy.

Abstract Introduction/Objective Composite classic Hodgkin lymphoma and follicular lymphoma (CHLFL), defined as CHL and FL occurring simultaneously at the same site, is rare and poorly understood. While both Hodgkin/Reed-Sternberg (HRS) cells and FL are thought to be derived from germinal center B-cells, the relationship between CHL and FL when coexistent is unclear. Here, we present two cases of CHLFL and show that the CHL and FL components have a clonal relationship by FISH. Methods/Case Report Case #1 is a 50-year-old man with abdominal and mediastinal lymphadenopathy. An excised mesenteric lymph node showed two distinct components diagnostic for FL, grade 1-2 and CHL. Case #2 is a 63-year- old woman with a history of FL with transformation to diffuse large B-cell lymphoma. Cytogenetic studies showed a complex karyotype with an add(9p), del(10q), and trisomy 16. Post-treatment imaging revealed left axillary adenopathy. An excised axillary lymph node showed CHL with peripheral areas of FL, grade 3A. Both cases had areas of typical FL with BCL2-positive phenotype and no significant CD30/CD15 expression. HRS cells were CD45/CD20-negative, expressed CD30 (strong), CD15, and PAX5, and were present in a mixed inflammatory background. No EBV RNA was present by in situ hybridization. Interestingly, HRS cells in case #1 expressed both BCL6 and BCL2. FISH was performed in both cases. Case #1 had a BCL2 rearrangement in 48% of FL nuclei and in 100% of HRS cells. In case #2, targeted probes were used based on prior cytogenetic results. Here, 47% of FL nuclei and 44% of HRS cells had a 16p duplication; additionally, 32% of HRS cells had an unbalanced IGH rearrangement with loss of the IGH variable region, suggesting possible clonal evolution. No rearrangement of BCL2 or BCL6 was present. An additional 27 CHLFL cases from the literature were reviewed. CHLFL was mostly nodal and occurred in late adulthood in patients with or without a history of FL. It presented at advanced clinical stage, with a 5-year overall survival of 22%. BCL2 expression in HRS cells was common. Bone marrow involvement was 45% (5/11) and consisted of FL exclusively. Five of six tested cases demonstrated BCL2/IGH rearrangement in both FL and HRS cells. Results (if a Case Study enter NA) NA Conclusion Composite CHL and FL are often clonally related and may share a common progenitor B-cell origin – likely a germinal center B-cell – from which additional genetic abnormalities are acquired to develop two distinct lymphomas.

Lymphomas usually involve lymph nodes and other lymphoid tissues, but sometimes occur in non-lymphoid organs, called extra-nodal sites. Primary diffuse extra-lymph node large B-cell lymphoma (DLBCL) of the thyroid and parotid gland have been observed rarely. According to the most accredited guidelines, primary extra-nodal DLBCL of the parotid and thyroid glands should be treated with three cycles of R-CHOP followed by radiotherapy of the involved site (ISRT). Surgery alone is not enough to treat DLBCL. We describe two unusual cases of primary extra-nodal DLBCL in elderly patients treated exclusively with surgical resection, given the inability to apply chemotherapy. Both patients achieved clinical recovery, which was maintained after a follow-up of more than 18 months, despite not having performed the indicated chemotherapy protocol. The two cases presented here, and a few others reported in the literature, should be considered exceptions to the rule, and do not allow the conclusion that surgery alone might be sufficient for complete remission.

An 8-y-old spayed female Beagle dog was presented with peripheral lymphadenomegaly. Lymph node cytology and flow cytometry led to the diagnosis of large B-cell lymphoma (LBCL). We detected minimal percentages of LBCL cells in peripheral blood and bone marrow samples. However, a monomorphic population of neoplastic cells different from those found in the lymph node was found in the bone marrow. T-cell acute lymphoblastic leukemia was suspected based on flow cytometric immunophenotyping. PCR for antigen receptor rearrangement (PARR) revealed clonal rearrangement of both B-cell and T-cell receptors, and the presence of both neoplastic clones in the lymph node, peripheral blood, and bone marrow. The dog was treated with multi-agent chemotherapy but died 46 d following diagnosis. Tumor staging and patient classification are needed to accurately establish a prognosis and select the most appropriate therapeutic protocol.
