Wang J, Zhou Y, Liu H, Zhou J, Li X. 18F-FDG PET/CT assists the diagnosis of primary pancreatic lymphoma: Two case reports and literature review. Front Med (Lausanne) 2024; 11:1370762. [PMID: 38463493 PMCID: PMC10924306 DOI: 10.3389/fmed.2024.1370762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Accepted: 02/09/2024] [Indexed: 03/12/2024] Open
Abstract
Primary pancreatic lymphoma (PPL) is a rare malignancy, which is defined as a mass centered in pancreas with involvement of contiguous lymph nodes and distant spread may exist. Accurate diagnosis of PPL prior to pathological confirmation remains challenging, underscoring the critical significance of preoperative imaging assessments. This case report collected two instances of PPL that underwent initial evaluation via 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) between August 2021 and July 2022. Correspondingly, pertinent literature encompassing 18F-FDG PET/CT data related to PPL was meticulously reviewed. Including our aforementioned pair of cases, a cumulative total of 25 instances of PPL were assembled. The distinctive profile of 18F-FDG PET/CT images of PPL predominantly manifests as hypermetabolic lesions with diminished density. Primarily characterized by singular lesions and comparatively substantial volumetric dimensions, a total of eleven cases revealed contiguous lymph node engagement, with five instances displaying distant dissemination encompassing lymph nodes in multiple locations. Amongst these, ten patients underwent sequential 18F-FDG PET/CT follow-up post-intervention. In comparison to pancreatic carcinoma, PPL lesions exhibited heightened hypermetabolism, augmented volumetric proportions, and distinct patterns of distant metastasis. This study indicates that the pivotal role of 18F-FDG PET/CT in the diagnosis and assessment of therapeutic efficacy in PPL is unequivocal. Combined with the clinical attributes of patients, the integration of 18F-FDG PET/CT augments the differential diagnostic capacity differentiating PPL from pancreatic carcinoma.

A case report of a collision tumor composed of pancreatic ductal adenocarcinoma and peri-pancreatic mucosa-associated lymphoid tissue lymphoma. World J Surg Oncol 2023; 21:110. [PMID: 36973717 PMCID: PMC10045193 DOI: 10.1186/s12957-023-02981-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 03/08/2023] [Indexed: 03/29/2023] Open
Abstract
BACKGROUND Collision tumors are composed of two distinct tumor components. Collision tumors composed of pancreatic ductal adenocarcinoma and malignant lymphoma occurring in the pancreas have not been previously described in the scientific literature. In this case report, we describe a unique patient with a collision tumor composed of pancreatic ductal adenocarcinoma and peri-pancreatic mucosa-associated lymphoid tissue (MALT) lymphoma occurring in the pancreas. CASE PRESENTATION An 82-year-old woman presented to our hospital complaining of dizziness. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a large lymphoid lesion spreading from the peri-pancreatic tissue heading to the hepatic hilar plate, involving the hepatoduodenal ligament and the entire duodenum, also showing a hard tumor in the pancreas head. We performed echo-guided needle biopsies for each tumor and diagnosed a collision tumor composed of pancreatic ductal adenocarcinoma and low-grade B cell lymphoma. The patient underwent pancreaticoduodenectomy. The resected specimen showed an elastic hard tumor, 90 × 75 mm in size, located in the pancreatic head, and a whitish-yellow hard tumor involving the lower bile duct, 31 mm in size, located in the center of the pancreatic head. Pathological and immunohistochemical examination proved that pancreatic ductal adenocarcinoma and MALT lymphoma originating from the peri-pancreatic head collided in the pancreatic head. CONCLUSIONS To best of our knowledge, this is the first report of a surgically resected collision tumor of pancreatic ductal adenocarcinoma and MALT lymphoma originating from the peri-pancreatic head. A needle biopsy is useful when inconsistent findings are observed on diagnostic CT and MRI of tumor lesions since there is the possibility of a collision tumor.

Abstract
Primary pancreatic lymphoma is a rare type of cancer, that accounts for 0.1-0.5% of lymphomas and about 0.2% of all primary pancreatic tumors. Diffuse Large B-cell Lymphoma is the most common subtype. The diagnosis is possible if the lymphoma is located in the pancreas, but the differential diagnosis with pancreatic ductal adenocarcinoma is difficult. The diagnostic accuracy of endosonography-guided fine needle aspiration is inadequate, and thus it is common to diagnose these masses only after surgical resection. The endosonography-guided tissue acquisition allows greater accuracy in the pancreatic masses, as it determines optimal access to histological analysis using tissue in paraffin blocks for complementary immunohistochemical, and molecular tests. Thus, this elaborate diagnostic environment allows the adoption of appropriate treatment strategies for patients with this condition. The authors describe four cases of primary pancreatic lymphoma indicated for surgical resection due to suspected pancreatic cancer, with the diagnosis of Diffuse Large B-cell Lymphoma obtained by endosonography-guided tissue acquisition, changing the therapeutic strategy through the adoption of adequate chemotherapy treatment with good progress.

Abstract
OBJECTIVES Primary pancreatic lymphoma (PPL) is rare, mimicking pancreatic ductal adenocarcinoma (PDAC) clinically and radiologically. The aim of this study is to evaluate the clinical, radiologic, and pathological characteristics of PPL diagnosed by fine-needle aspiration (FNA) in our institution. METHODS Patient clinical, radiologic, and pathological information was collected from the electronic health record system. RESULTS In total, 11 of 4,353 pancreatic FNAs met the criteria. The most common clinical symptom was jaundice, followed by abdominal pain, weight loss, and diarrhea. Abnormal laboratory findings included elevated alkaline phosphatase, total bilirubin, lactate dehydrogenase, and cancer antigen 19-9. Abnormal radiologic findings included pancreatic mass, biliary dilatation, vessel encasement, and common bile duct encasement and thickening. Five patients underwent more than 1 tissue sampling procedure before the final diagnosis of lymphoma. Final pathologic diagnosis included 7 large B-cell lymphomas and 4 follicular lymphomas. Flow cytometric analysis was performed on 9 specimens, and all demonstrated an aberrant monoclonal B-cell population. CONCLUSIONS PPL mimics PDAC clinically and radiologically and could be a challenge for pathologic diagnosis if lymphoma is not included in the differential diagnosis during immediate evaluation. If lymphoma is suspected during immediate evaluation, PPL could be reliably diagnosed by FNA with the aid of ancillary studies.

Abstract
Involvement of the abdomen and pelvis is common in lymphoma. Nodal and extranodal abdominal and pelvic lymphoma may present with various complications. Complications are most common in high-grade lymphomas, especially diffuse large B-cell lymphoma. Complications may occur as the initial manifestation of lymphoma, during treatment course, or late following complete disease remission. Most complications are associated with worse prognosis and increased mortality. Imaging is essential in evaluation of disease extent and diagnosis of complications. Therefore, radiologists should be familiar with the clinical context and imaging features of abdominal and pelvic lymphoma complications. We provide a comprehensive, organ system-based approach, and clinical and imaging review of complications of abdominal and pelvic lymphoma along with radiologic images of illustrated cases of the most commonly encountered complications.

Abstract
Endoscopic-ultrasonography-guided tissue acquisition (EUS-TA) has been widely performed for the definitive diagnosis of solid pancreatic lesions (SPLs). As the puncture needles, puncture techniques, and sample processing methods have improved, EUS-TA has shown higher diagnostic yields and safety. Recently, several therapeutic target genomic biomarkers have been clarified in pancreatic ductal carcinoma (PDAC). Although only a small proportion of patients with PDAC can benefit from precision medicine based on gene mutations at present, precision medicine will also be further developed for SPLs as more therapeutic target genomic biomarkers are identified. Advances in next-generation sequencing (NGS) techniques enable the examination of multiple genetic mutations in limited tissue samples. EUS-TA is also useful for NGS and will play a more important role in determining treatment strategies. In this review, we describe the utility of EUS-TA for SPLs.

Abstract
INTRODUCTION Primary pancreatic B-cell lymphoma is rare with most common type being Diffuse Large B-cell lymphoma (DLBCL). Anaplastic lymphoma kinase-positive large B-cell lymphoma (ALK+ LBCL) represents less than 1% of all DLBCL. Extra-nodal presentation is rare with presentation as a primary pancreatic mass being exceptional. CASE REPORT A 42 years female presented with lump in central upper abdomen for one month with evidence of icterus. Lab Investigations showed deranged Total Bilirubin/Direct Bilirubin, AST, ALT, ALP, Amylase, Lipase, CEA, CA 19-9 and CA-125 levels. CECT scan showed large solid mass in pancreas with necrotic areas within. Biopsy revealed a lymphoma with strong expression of ALK (granular cytoplasmic), CD138, MUM1, kappa, moderate expression of CD45 and focal expression of CD20, CD79a and PAX5 and lack of expression of CD5, CD3, CD45RO, BCL6, CD10 and EMA. FNAC and Flow Cytometry was also performed. A final diagnosis of ALK positive LBCL was made with pancreas as primary. CONCLUSION Present case is the first case of ALK positive LBCL reported in pancreas. Expression of mature B-cell markers such as CD20, CD79a and light chain restriction may be seen unlike previous claims.

Abstract
A 68-year-old man with epigastric pain was admitted for acute pancreatitis and obstructive jaundice caused by Primary pancreatic malignant lymphoma. Computed tomography showed diffuse enlargement of the whole pancreas and dilation of the main pancreatic duct and bile duct. Endoscopic retrograde cholangiopancreatography was performed to decompress these dilated ducts. After two courses of chemotherapy, follow-up computed tomography incidentally revealed migration of the pancreatic duct stent, which had perforated the contralateral duodenal wall to enter the peritoneal cavity. In the present case, pancreatic duct stent deviation was attributed to tumor shrinkage resulting from chemotherapy. In addition, stent migration into the peritoneal cavity occurred due to repeated mechanical manipulation of the pancreatic duct stent, presumably leading to partial ulceration of the duodenal wall and delayed wound healing during chemotherapy. This case may provide valuable information on the migration of pancreatic duct stents as a rare, stent-related late complication during chemotherapy.

Abstract
BACKGROUND Primary pancreatic lymphoma (PPL) is a rare disease representing 0.1% of all malignant lymphomas, which lacks well-defined diagnostic and therapeutic protocols. We conducted a systematic review to analyze demographic, diagnostic and therapeutic features of PPL. METHODS This review identified small series and single case reports. Sources were MEDLINE, PubMed, and the Cochrane library from January 2001 to December 2020. Data were screened, extracted and the risk of bias analyzed by three independent reviewers. RESULTS A total of 107 eligible papers (17 small series, 90 single case reports) describing 266 patients were identified. Patients had a median age of 53.1 (range 3-86) years and were males in 64.6% of cases. Abdominal pain and jaundice were the most common presenting symptoms, affecting 75.3% and 41.8% of patients, respectively. PPL had a median size of 60.6 mm (range 16-200) and it was localized in the pancreatic head in 63.7% of cases. At diagnosis most patients underwent ultrasonography followed by computed tomography. PPL typically showed low echogenicity, and lower contrast enhancement than solid tumors. Histopathological specimens were obtained by percutaneous or endoscopic biopsies in 47.7% of patients; abdominal surgery was performed in 33.5% of cases. Overall, diffuse large B-cell lymphoma was the most frequent histological diagnosis (53.6%). However, patients aged <18 years were affected by Burkitt lymphoma in 52.4% of cases. Most patients (53.6%) received immunochemotherapy (IC) or IC plus radiotherapy (14%). Demolitive surgery appeared to be associated with impaired survival. Central nervous system (CNS) relapse or progression was observed in 20% of patients. CONCLUSION PPL is a rare entity, with some peculiar features at modern imaging. For diagnostic purposes percutaneous or endoscopic biopsies might be preferable, as opposed to surgery. No definite data is available about the optimal treatment, which should be tailored on the histological type and associated with CNS prophylaxis.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the diagnostic tool of choice for pancreatic solid mass lesions. Pancreatic lymphomas represent an infrequent and challenging cytologic diagnosis. Our aim was to determine the diagnostic value of cellblock (CB) in the diagnosis of pancreatic lymphomas. METHODS We retrieved pancreatic EUS-FNAs performed over 10-years from our institution's database. We correlated the cytologic and CB diagnosis with the histologic diagnosis as a gold standard. RESULTS We found 5 cases (2 women and 3 men; age range, 37-66 years [average age, 52 years]) of pancreatic lymphomas with histologic follow-up biopsies. They included 1 case of T-cell lymphoma (TCL), 1 case of plasma cell neoplasm (multiple myeloma [MM]), 1 case of diffuse large B-cell lymphoma (DLBCL), 1 case of classic Hodgkin lymphoma (HL), and 1 case of high-grade B-cell lymphoma (HGBCL). Cytologically, the cases of HL and DLBCL were suspected, the cases of TCL and MM were confused with undifferentiated carcinoma and neuroendocrine carcinoma, and the case of HGBCL was inconclusive. CB samples were of value in highlighting the morphologic details of lymphomas and allowed confirmation, proper classification, and grading of the lymphomas using immunohistochemistry that matched tissue biopsies. CONCLUSIONS EUS-FNA smears with CBs are helpful diagnostic tools, differentiating lymphomas from other malignancies and from nonneoplastic lymphocyte-rich lesions. CBs allow proper classification and grading of cases of pancreatic lymphomas.

Abstract
Hepatic abnormalities in patients with lymphoproliferative disorders are common and can occur from direct infiltration by abnormal cells, bile duct obstruction, paraneoplastic syndrome, hemophagocytic syndrome, drug-induced liver injury, opportunistic infections, and reactivation of viral hepatitis. Hepatic involvement by lymphoma is often in association with systemic disease and rarely seen as a primary hepatic lymphoma. Vanishing bile duct syndrome is a well-known complication of Hodgkin disease. Antiviral prophylaxis for hepatitis B virus (HBV) reactivation is recommended for all HBsAg+ patients undergoing chemotherapy and all resolved HBV patients undergoing rituximab therapy and stem cell transplantation.

Abstract
Le lymphome malin non hodgkinien (LMNH) primitif du pancréas est une localisation extrêmement rare des LMNH extraganglionnaires représentant moins de 0,7% de tous les LMNH et moins de 0,5% des tumeurs malignes pancréatiques, touchant essentiellement le sujet âgé et très rarement le sujet jeune (l'intérêt de notre cas). Son diagnostic est difficile simulant cliniquement l'adénocarcinome de pancréas et les pancréatites chroniques. Nous rapportons le cas d'un patient de 25ans, suivi pour lymphome non hodgkinien (LNH) diffus à grandes cellules B de localisation pancréatique primitive révélé par des épigastralgies avec ictère foudroyant d'installation brutale dans un contexte d'altération de l'état général et diagnostiqué sur une biopsie de la loge duodéno-pancréatique. Le diagnostic et la prise en charge précoce de ces tumeurs agressives permettent d'améliorer significativement leur pronostic.

INTRODUCTION Secondary pancreatic tumors are uncommon and account for 2-5% of pancreatic cancer. Tumors characterized most commonly with pancreatic involvement are lymphoma, renal cell and lung carcinomas. PRESENTATION OF CASE A 76-year-old female patient with obstructive jaundice as the primary symptom and inguinal lymphadenopathy is presented. Imaging revealed a bulky solitary solid pancreatic head mass along with paraaortic and mesenteric lymphadenopathy. The absence of a previous history of malignancy and the presence of a dominant pancreatic mass along with distal lymphadenopathy confined differential diagnosis to advanced secondary pancreatic lymphoma, which is the most common secondary pancreatic tumor, and locally advanced/metastatic pancreatic adenocarcinoma. Pathologic confirmation with excisional biopsy of an enlarged inguinal lymph node and EUS-FNB of the pancreatic head mass confirmed the diagnosis of secondary Non-Hodgkin pancreatic lymphoma allowing initiation of induction chemotherapy. DISCUSSION Secondary pancreatic lymphoma can be seen up to 30% of patients with advanced lymphoma; although the head of the pancreas is the most common location, obstructive jaundice is not the predominant symptom as obstruction of the common bile duct is usually absent. In the setting of a solitary nodular type pancreatic mass, key imaging findings highly suggestive of secondary pancreatic lymphoma and not of adenocarcinoma are the absence of vascular invasion, bile and pancreatic duct obstruction, and the presence of lymphadenopathy below the level of the left renal vein. CONCLUSION When a secondary pancreatic tumor is highly suspected pathologic confirmation is always needed before initiation of induction or palliative chemotherapy.

Abstract
Hodgkin's lymphoma is a group of malignant lymphoid which involve various organs including gastrointestinal tract. Stomach and small intestine are commonly involved more; however, pancreas can be primarily involved as well. The secondary involvement of pancreas caused by Hodgkin's lymphoma is more prevalent than the primarily involvement (1 .25-2.2% vs. <1%). Primary pancreatic lymphomas (PPLs) consist of 1-2% of all lymphoma outside nods. The symptoms and findings of PPL imaging can be akin to that of pancreas adenocarcinoma and differentiating them is difficult without examining the tissue sample. The prognosis and treatment of PPL are different from those of adenocarcinoma and due to the superior prognosis of PPL compared to pancreas adenocarcinoma, the proper diagnosis of the disease is important.

Abstract
Primary pancreatic lymphoma (PPL) is an extremely rare disease, with only a few cases reported in the literature. Clinical manifestations of PPL are often nonspecific and may mimic other pancreatic diseases. Because of the limited experience of PPL, clinicopathological features, differential diagnosis, optimal therapy, and outcomes are not well defined. We described two cases diagnosed as PPL and confirmed by histological examination and immunohistochemical analysis. Case 1 was a young man with obstructive jaundice and upper abdominal malaise mimicking a pancreatic adenocarcinoma. A computed tomography (CT) scan revealed a diffuse heterogeneous mass in the head of the pancreas along with dilated bile ducts, no dilated pancreatic duct, no liver or splenic involvement, or evident retroperitoneal adenopathies. The patient underwent a pancreatico-duodenectomy, and the postoperative histopathology confirmed diffuse large B-cell non-Hodgkin lymphoma. Postoperatively, he received six courses of the CHOP regimen (cyclophosphamide, doxorubicin, vincristine, and prednisolone). Case 2 was an older man with left flank pain. A CT confirmed a mass with irregular margins at the tail of the pancreas and the hilum of the spleen. The mass was heterogeneous, with no clear boundary between lesions, spleen, stomach, and pancreas, with nearby blood vessels wrapped around it, and multiple enlarged lymph nodes in the abdominal cavity. A CT-guided biopsy was performed. The immunohistological findings of the specimen revealed a diffuse large B-cell lymphoma. The size of the tumor was significantly reduced after four cycles of the CHOP chemotherapy regimen. These two cases were different in clinical manifestation, location, and treatment. We reviewed the literature and discussed the clinicopathological features, differential diagnosis, optimal therapy, and outcomes of this neoplasm.

Abstract
Pancreatic cytopathology, particularly through the use of endoscopic ultrasound-guided fine-needle aspiration (FNA), has excellent specificity and sensitivity for the diagnosis of pancreatic lesions. Such diagnoses can help guide preoperative management of patients, provide prognostic information, and confirm diagnoses in patients who are not surgical candidates. Furthermore, FNA can be used to obtain cyst fluid for ancillary tests that can improve the diagnosis of cystic lesions. In this article, we describe the cytomorphological features and differential diagnoses of the most commonly encountered pancreatic lesions on FNA.

Abstract
Evaluation of deep-seated lymphomas by fine-needle aspiration (FNA) can be challenging due to their reduced accessibility. Controversy remains as to whether FNA and ancillary techniques can be used to diagnose deep-seated lymphomas reliably and sufficiently for clinical management. Most published studies are favorable that endobronchial ultrasound (EBUS)/endoscopic ultrasound (EUS)-FNA plays an important role in the diagnosis of deep-seated lymphomas. The addition of ancillary techniques, particularly flow cytometry, increases diagnostic yield. While subclassification is possible in a reasonable proportion of cases, the reported rates of successful subclassification are lower than those for lymphoma detection/diagnosis. The diagnostic limitation exists for Hodgkin's lymphoma, grading of follicular lymphoma, and some T-cell lymphomas. The role of FNA in deep-seated lymphomas is much better established for recurrent than primary disease. It remains unclear whether the use of large-sized-needle FNA or a combination of core needle biopsy and FNA improves subclassification. It is important for cytopathologists to have considerable understanding of the WHO lymphoma classification and develop a collaborative working relationship with hematopathologists and oncologists. As EUS/EBUS-FNA techniques advance and sophisticated molecular techniques such as next- generation sequencing become possible, the role of FNA in the diagnosis of deep-seated lymphomas will possibly increase.

Abstract
OBJECTIVE This article reviews the computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET) CT findings of primary and secondary pancreatic lymphomas and discusses the role of endoscopic ultrasound-guided fine needle aspiration in diagnosis and management. CONCLUSION Pancreatic lymphoma has certain characteristic imaging features which may help distinguish it from the more common pancreatic adenocarcinoma. It is critical to make an accurate diagnosis, as the management of these two conditions is vastly different.
