[PMID: 38660638 PMCID: PMC11037062 DOI: 10.4251/wjgo.v16.i4.1668] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Revised: 01/25/2024] [Accepted: 02/29/2024] [Indexed: 04/10/2024] Open
Abstract
BACKGROUND Primary pancreatic lymphoma (PPL) is an exceedingly rare tumor with limited mention in scientific literature. The clinical manifestations of PPL are often nonspecific, making it challenging to distinguish this disease from other pancreatic-related diseases. Chemotherapy remains the primary treatment for these individuals.
CASE SUMMARY In this case study, we present the clinical details of a 62-year-old woman who initially presented with vomiting, abdominal pain, and dorsal pain. On further evaluation through positron emission tomography-computed tomography, the patient was considered to have a pancreatic head mass. However, subsequent endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) revealed that the patient had pancreatic peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). There was a substantial decrease in the size of the pancreatic mass after the patient underwent a cycle of chemotherapy comprised of brentuximab vedotin, gemcitabine, and oxaliplatin (brentuximab vedotin and Gemox). The patient had significant improvement in radiological findings at the end of the first cycle.
CONCLUSION Primary pancreatic PTCL-NOS is a malignant and heterogeneous lymphoma, in which the clinical manifestations are often nonspecific. It is difficult to diagnose, and the prognosis is poor. Imaging can only be used for auxiliary diagnosis of other diseases. With the help of immunostaining, EUS-FNA could be used to aid in the diagnosis of PPL. After a clear diagnosis, chemotherapy is still the first-line treatment for such patients, and surgical resection is not recommended. A large number of recent studies have shown that the CD30 antibody drug has potential as a therapy for several types of lymphoma. However, identifying new CD30-targeted therapies for different types of lymphoma is urgently needed. In the future, further research on antitumor therapy should be carried out to improve the survival prognosis of such patients.

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.

Abstract
Several solid lesions can be found within the pancreas mainly arising from the exocrine and endocrine pancreatic tissue. Among all pancreatic malignancies, the most common subtype is pancreatic ductal adenocarcinoma (PDAC), to a point that pancreatic cancer and PDAC are used interchangeably. But, in addition to PDAC, and to the other most common and well-known solid lesions, either related to benign conditions, such as pancreatitis, or not so benign, such as pancreatic neuroendocrine neoplasms (pNENs), there are solid pancreatic lesions considered rare due to their low incidence. These lesions may originate from a cell line with a differentiation other than exocrine/endocrine, such as from the nerve sheath as for pancreatic schwannoma or from mesenchymal cells as for solitary fibrous tumour. These rare solid pancreatic lesions may show a behaviour that ranges in a benign to highly aggressive malignant spectrum. This review includes cases of an intrapancreatic accessory spleen, pancreatic tuberculosis, solid serous cystadenoma, solid pseudopapillary tumour, pancreatic schwannoma, purely intraductal neuroendocrine tumour, pancreatic fibrous solitary tumour, acinar cell carcinoma, undifferentiated carcinoma with osteoclastic-like giant cells, adenosquamous carcinoma, colloid carcinoma of the pancreas, primary leiomyosarcoma of the pancreas, primary and secondary pancreatic lymphoma and metastases within the pancreas. Therefore, it is important to determine the correct diagnosis to ensure optimal patient management. Because of their rarity, their existence is less well known and, when depicted, in most cases incidentally, the correct diagnosis remains challenging. However, there are some typical imaging features present on cross-sectional imaging modalities that, taken into account with the clinical and biological context, contribute substantially to achieve the correct diagnosis.

Abstract
BACKGROUND Pancreatic lymphomas (PLs) represent <2% of all lymphomas and <0.5% of all pancreatic neoplasms. An accurate histologic diagnosis of PL is needed to predict prognosis and adequately treat the patient. This study aims to investigate the demographic, clinical, and pathological factors affecting the prognosis and survival of pancreatic diffuse large B-cell lymphoma (DLBCL). METHODS Demographic and clinical data from 493 cases of DLBCL of the pancreas were identified between 2000 and 2018 using the Surveillance, Epidemiology, and End Results (SEER) database. RESULTS The most common age group was between the ages of 70 and 79 years (27.0%). While 44% of cases involved distant sites (a proxy for secondary pancreatic DLBCL), regional and localized involvement was seen in 33%, with the most common cause of death being a primary pancreatic DLBCL. Most patients (71%) received only chemotherapy (systemic therapy). The overall five-year observed survival was 46% (95% CI, 43.5-48.3). The one-year and five-year survival with chemotherapy only was 68% (95% CI, 65.3-70.3) and 48% (95% CI, 44.7-50.5), respectively. The one-year and five-year survival with surgery and chemotherapy was 96% (95% CI, 91.3-99.9) and 80% (95% CI, 71.4-89.2), respectively. Surgery with chemotherapy (HR: 0.397 (95% CI, 0.197-0.803), p = 0.010) were both positive predictors in survival prognosis. Multivariable analysis identified age >55 years (HR: 2.475 (95% CI, 1.770-3.461), p < 0.001), distant stage (HR: 6.894 (95% CI, 4.121-11.535), p < 0.001), and undergoing no surgery (HR: 2.610 (95% CI, 1.307-5.215), p = 0.007) as negative predictors for survival. CONCLUSION PLs are rare malignant pancreatic neoplasms with DLBCL being the most common histological subtype. An accurate and timely diagnosis of pancreatic DLBCL is necessary to implement effective treatments and reduce mortality. Systemic therapy (chemotherapy) with or without surgical therapy improved survival. Increased age and regional and distant spread negatively impacted survival.

Abstract
Primary pancreatic lymphoma is a rare pancreatic malignancy, reportedly accounting for only 0.2-0.7% of all primary pancreatic tumors. Primary pancreatic lymphoma is often difficult to distinguish from other diseases, such as acute pancreatitis. We herein report the autopsy of a patient with primary pancreatic lymphoma with imaging findings resembling those of severe acute pancreatitis, with a focus on the gross and histological features.

Abstract
Primary hepatopancreatobiliary lymphoma (PHPBL) is extremely rare, which is defined as a lympho-proliferative disease confined to the hepatobiliary system and pancreas without any involvement of lymph nodes, bone marrow, or other organs. The clinical and imaging manifestations of PHPBL are variable and non-special, which are akin to those of tumors of the hepatobiliary and pancreatic systems. The overall prognosis and management of PHPBL differ from those of other tumors in the hepatobiliary system and pancreas. Proper diagnosis and prompt treatment are essential for improving clinical outcomes. Due to its rarity, the optimal treatment has not been issued. However, combination chemotherapy is considered as a standard treatment for them. This review provides an overview of the pathogenesis, diagnosis, pathology, and management of PHPBL and offers clinicians the diagnosis and management schedule for PHPBL.

World J Clin Oncol 2021; 12:823-832. [PMID: 34631445 PMCID: PMC8479350 DOI: 10.5306/wjco.v12.i9.823] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Revised: 06/29/2021] [Accepted: 08/10/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Primary pancreatic lymphoma (PPL) is a rare neoplasm. Being able to distinguish it from other pancreatic malignancies such as pancreatic ductal adenocarcinoma (PDAC) is important for appropriate management. Unlike PDAC, PPL is highly sensitive to chemotherapy and usually does not require surgery. Therefore, being able to identify PPL preoperatively will not only direct physicians towards the correct avenue of treatment, it will also avoid unnecessary surgical intervention.
AIM To evaluate the typical and atypical multi-phasic computed tomography (CT) imaging features of PPL.
METHODS A retrospective review was conducted of the clinical, radiological, and pathological records of all subjects with pathologically proven PPL who presented to our institutions between January 2000 and December 2020. Institutional review board approval was obtained for this investigation. The collected data were analyzed for subject demographics, clinical presentation, laboratory values, CT imaging features, and the treatment received. Presence of all CT imaging findings including size, site, morphology and imaging characteristics of PPL such as the presence or absence of nodal, vascular and ductal involvement in these subjects were recorded. Only those subjects who had a pre-treatment multiphasic CT of the abdomen were included in the study.
RESULTS Twenty-nine cases of PPL were diagnosed between January 2000 and December 2020 (mean age 66 years; 13 males/16 females). All twenty-nine subjects were symptomatic but only 4 of the 29 subjects (14%) had B symptoms. Obstructive jaundice occurred in 24% of subjects. Elevated lactate dehydrogenase was seen in 81% of cases, whereas elevated cancer antigen 19-9 levels were present in only 10% of cases for which levels were recorded. The vast majority (90%) of tumors involved the pancreatic head and uncinate process. Mean tumor size was 7.8 cm (range, 4.0-13.8 cm). PPL presented homogenous hypoenhancement on CT in 72% of cases. Small volume peripancreatic lymphadenopathy was seen in 28% of subjects. Tumors demonstrated encasement of superior mesenteric vessels in 69% of cases but vascular stenosis or occlusion only manifested in 5 out of the twenty-nine individuals (17%). Mild pancreatic duct dilatation was also infrequent and seen in only 17% of cases, whereas common bile duct (CBD) dilation was seen in 41% of subjects. Necrosis occurred in 10% of cases. Size did not impact the prevalence of pancreatic and CBD dilation, necrosis, or mesenteric root infiltration (P = 0.525, P = 0.294, P = 0.543, and P = 0.097, respectively). Pancreatic atrophy was not present in any of the subjects.
CONCLUSION PPL is an uncommon diagnosis best made preoperatively to avoid unnecessary surgery and ensure adequate treatment. In addition to the typical CT findings of PPL, such as homogeneous hypoenhancement, absence of vascular stenosis and occlusion despite encasement, and peripancreatic lymphadenopathy, this study highlighted many less typical findings, including small volume necrosis and pancreatic and bile duct dilation.

Abstract
Hematologic malignancies represent a vast group of hematopoietic and lymphoid cancers that typically involve the blood, the bone marrow, and the lymphatic organs. Due to extensive research and well defined and standardized response criteria, the role of [18F]FDG-PET/CT is well defined in these malignancies. Never the less, the reliability of visual and quantitative interpretation of PET/CT may be impaired by several factors including inconsistent scanning protocols and image reconstruction methods. Furthermore, the uptake of [18F]FDG not only reflects tissue glucose consumption by malignant lesions, but also in other situations such as in inflammatory lesions, local and systemic infections, benign tumors, reactive thymic hyperplasia, histiocytic infiltration, among others; or following granulocyte colony stimulating factors therapy, radiation therapy, chemotherapy or surgical interventions, all of which are a potential source of false-positive or negative interpretations. Therefore it is of paramount importance for the Nuclear Medicine Physician to be familiar with, not only the normal distribution of [18F]FDG in the body, but also with the most frequent findings that may hamper a correct interpretation of the scan, which could ultimately alter the patients management. In this review, we describe these myriad of situations so the interpreting physician can be familiar with them, providing tools for their correct identification and interpretation when possible.

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
Primary pancreatic lymphoma (PPL) is an extremely rare form of extranodal malignant lymphoma. The most common histological subtype of PPL is diffuse large B-cell lymphoma (DLBCL). Clinical and imaging features of PPL may often overlap with pancreatic adenocarcinoma. Therefore, it is very important to obtain a preoperative cytohistology diagnosis of pancreatic tumors to avoid unnecessary surgeries in cases with a diagnosis of PPL. Herein, we report a 71-year-old male who was admitted to our hospital with a diagnosis of acute pancreatitis after he presented with complaints of nausea, vomiting, and epigastric abdominal pain. MRI of the abdomen revealed a pancreatic head mass, and histopathology and immunohistochemical assessment of the pancreatic lesion established the diagnosis of DLBCL. The patient achieved remission after six cycles of rituximab-cyclophosphamide, doxorubicin (hydroxydaunomycin), vincristine (oncovin), prednisolone (R-CHOP) chemotherapy.

Abstract
BACKGROUND Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) is a rare subtype of B-cell neoplasm that can have diverse presentations. When it involves the pancreas (i.e., pancreatic lymphoma), it can mimic metastatic pancreatic adenocarcinoma. Pancreatic lymphoma and adenocarcinoma often have similar clinical, laboratory, and radiographic features making the distinction challenging without pathological tissue examination. The differentiation of these 2 entities is important as the prognosis of pancreatic lymphoma is certainly more favorable with a chance of cure with chemoimmunotherapy. CASE REPORT We present an unusual case of EBV-positive DLBCL involving the pancreas that was initially believed to be metastatic pancreatic adenocarcinoma. The patient was treated with chemoimmunotherapy and had a remarkable response. This is the first known case of EBV-positive DLBCL involving the pancreas that was successfully treated with chemoimmunotherapy. CONCLUSIONS EBV-positive DLBCL can have diverse presentations, including a pancreatic mass with multi-organ involvement, which mimics metastatic pancreatic adenocarcinoma. The prognosis of EBV-positive DLBCL is thought to be worse than that of EBV-negative tumors. However, it remains certainly superior to that of its adenocarcinoma counterpart with conventional chemoimmunotherapy.

Abstract
Adenocarcinoma is the most common primary pancreatic neoplasm type, followed by secondary pancreatic lymphoma and primary pancreatic lymphoma (PPL). PPL is associated with peripancreatic lymphadenopathy and usually presents as a homogenous mass with extrapancreatic invasion into surrounding structures. However, localized involvement of the distal pancreas is uncommon, and diffuse involvement of the pancreas is even rarer. Herein, we present the case of a 53-year-old woman with PPL of the uncinate process with biliary obstruction mimicking pancreatic adenocarcinoma, successfully diagnosed nonoperatively. Abdominal computed tomography showed an ill-defined uncinate process mass, hypodense with mild enhancement (3.9 × 3.4 × 3.5 cm), infiltrating the second and third parts of the duodenum. Biopsy revealed NHL with no evidence of adenocarcinoma. PPL was diagnosed. She received chemotherapy with a CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) protocol with rituximab, which she tolerated with no clinical or radiological evidence of recurrence at 1-year follow-up.

Abstract
Primary pancreatic lymphoma is a rare clinical entity representing <0.5% of pancreatic cancers and 1% of extranodal lymphomas. Due to the paucity of cases described in the literature, its clinicopathological features, differential diagnosis, optimal therapy and outcomes are not well defined. As the clinical manifestations are often non-specific, it can create a diagnostic pitfall for the unwary physician. Preoperative distinction of adenocarcinoma and primary pancreatic lymphoma is critical since the management and prognosis of these malignancies are mutually exclusive. Due to its rarity, epidemiological studies have been difficult to conduct. Chemotherapy with R-CHOP (rituximab, cyclophosphamide, doxorubicin and vincristine) has proven to be effective. The authors present the case of a 52-year-old man with epigastric pain and obstructive jaundice. Further investigation with a CT of the abdomen and pelvis showed a low attenuation mass in the head of the pancreas measuring 35×25 mm, suspicious for malignancy. The mass involved the common bile duct distally causing moderate retrograde intrahepatic and extrahepatic biliary tree dilation of 14 mm. He underwent endoscopic retrograde cholangiopancreatography, sphincterotomy and insertion of a stent. Core biopsies confirmed the diagnosis of a high-grade B cell pancreas lymphoma. He started treatment with R-CHOP and prednisolone. Due to disease progression, he started treatment with DA-EPOCH-R (etoposide phosphate, prednisone, vincristine sulfate, cyclophosphamide, doxorubicin hydrochloride and rituximab). There was no clinical response, and treatment with RICE (rituximab, ifosfamide, carboplatin and etoposide) was initiated. He showed partial response and was under consideration for chimeric antigen receptor T cell therapy. He deteriorated clinically and succumbed to his disease 5 months following his initial presentation. This paper will provide an overview of the spectrum of haematological malignancies and describe useful features in distinguishing primary lymphoma of the pancreas from an adenocarcinoma, hence avoiding its surgical resection.

Abstract
Advanced methods of molecular characterization have elucidated the genetic, epigenetic, and proteomic alterations associated with the broad spectrum of pancreatic disease, particularly neoplasia. Next-generation sequencing, in particular, has revealed the genomic diversity among pancreatic ductal adenocarcinoma, neuroendocrine and acinar tumors, solid pseudopapillary neoplasm, and other pancreatico-biliary neoplasms. Differentiating these entities from one another by morphologic analysis alone may be challenging, especially when examining the small quantities of diagnostic material inherent to cytologic specimens. In order to enhance the sensitivity and specificity of pancreatic cytomorphology, multiple diagnostic, prognostic, and predictive ancillary tests have been and continue to be developed. Although a great number of such tests have been developed for evaluation of specimens collected from cystic lesions and strictures, ancillary techniques also play a significant role in the evaluation of cytologic specimens obtained from solid lesions of the pancreas. Furthermore, while some tests have been developed to differentiate diagnostic entities from one another, others have been developed to simply identify dysplasia and malignancy. Ancillary studies are particularly important in the subset of cases for which cytomorphologic analysis provides a result that is equivocal or insufficient to guide clinical management. Selection of appropriate ancillary testing modalities requires familiarity with both their methodology and the molecular basis of the pancreatic diseases for which testing is being performed.

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.

Abstract
Majority of malignant pancreatic neoplasms are epithelial in origin and mostly arise from exocrine gland. Ductal adenocarcinoma compromises the major histological type of such tumors. Primary non-epithelial tumors of exocrine pancreatic gland are extremely rare and incorporate lymphoma and sarcoma. Primary pancreatic lymphoma compromises less than 0.5% of pancreatic malignancies. Primary pancreatic lymphoma can be difficult to differentiate from pancreatic adenocarcinoma and other neoplasms on imaging, and a correct diagnosis is crucial for appropriate patient management.

Abstract
Aims and backgrounds Primary pancreatic lymphoma is non-Hodgkin lymphoma primarily involving the pancreas, which is rare in pancreatic diseases. The aim of this work is to summarize the diagnostic and therapeutic experience of primary pancreatic lymphoma. Methods We retrospectively reviewed the clinical data of 7 cases of primary pancreatic lymphoma admitted to Huashan Hospital in the past 3 years. Available English literature was also reviewed using the following terms: primary pancreatic lymphoma and pancreatic lymphoma. Results The literature review identified 157 additional cases, and a total of 164 cases had been analyzed. In this series, only 30% had a successful non-operative diagnosis. The curative rate of the surgery-adjuvant chemotherapy group was higher than that of the chemotherapy alone group. Conclusions Obtaining specimens through surgery is an effective diagnostic tool. Surgical resection in combination with postoperative chemotherapy plays a therapeutic role.

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
Primary pancreatic lymphoma is an unlikely malignancy accounting for less than 0.5% of pancreatic tumors. Clinical presentation is often nonspecific and may be clinically misdiagnosed as pancreatic adenocarcinoma. Here we present an Iranian case of primary pancreatic lymphoma in a 47-year-old male suffering from jaundice and 20% weight loss. Endoscopic ultrasound revealed a mixed echoic mass lesion at the head of pancreas. The patient underwent endoscopic ultrasound-guided fine needle aspiration of solid pancreatic mass and histopathologic diagnosis revealed granuloma. Computed tomography-guided core needle biopsy was performed and eventually histological examination showed granuloma that was coherent with the diagnosis of primary pancreatic lymphoma. Primary pancreatic lymphoma is a rare entity presenting with nonspecific symptoms, laboratory and radiological findings. Computed tomography results in combination with clinical and radiological studies generally provide guidance for appropriate investigation.

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.

Hematologic malignancies are relatively uncommon neoplasms of abdominal soft tissue. This article discusses the clinical and imaging features of pancreatic lymphoma, pancreatic extraosseous multiple myeloma, granulocytic sarcoma (chloroma), posttransplant lymphoproliferative disorder, and Castleman disease. The combination of imaging findings and the appropriate clinical presentation should allow the radiologist to raise a provisional diagnosis of hematologic malignancy.

Abstract
INTRODUCTION Primary pancreatic lymphoma (PPL) is a rare tumor that is often misdiagnosed. Clinicopathologic features, optimal therapy, and outcomes are not well defined. We reviewed our institutional experience with PPL. METHODS Search of our institutional database identified that between 1987-2012, 21,760 patients with lymphoma and 11,286 patients with a primary pancreatic tumor were evaluated. There were 44 patients with pathologically confirmed PPL. Clinical data were obtained by chart review and survival distributions were estimated using the Kaplan-Meier method and compared using the log-rank test. RESULTS At baseline, LDH was elevated in 55 % of the patients, CA 19-9 in 25 %, and CEA in 20 %. Imaging characteristics included large, unresectable tumors (67 %), and lymphadenopathy inferior to the renal vein (50 %). Twenty-three patients underwent surgery for resection (5), diagnosis (13), or palliation (5). Chemotherapy alone achieved a 75 % complete response rate. Eight patients experienced relapse, 88 % of which occurred at distant sites. Median overall survival was 6.1 years and 10-year disease-specific survival (DSS) was 69 %. Patients with a low risk International Prognostic Index (IPI) and those with a follicular histologic subtype demonstrated 5-year DSS of 100 %. CONCLUSIONS Chemotherapy for PPL results in a high complete response rate and long DSS, which is similar to nodal non-Hodgkin's lymphoma (NHL). A favorable outcome is expected for IPI low risk patients and follicular histologic subtype. Systemic therapy should generally be the initial therapy when the diagnosis is known. Prolonged follow up is recommended to detect relapses. Surgery alone should be reserved for non-curative intent (i.e. diagnostic or palliative).

Abstract
Pancreatic tumors are an increasingly common finding in abdominal imaging. Various kinds of pathologies of the pancreas are well known, but it often remains difficult to classify the lesions radiologically in respect of type and grade of malignancy. Magnetic resonance imaging (MRI) is the method of choice for the evaluation of pancreatic pathologies due to its superior soft tissue contrast. In this article we present a selection of less common malignant and potentially malignant pancreatic neoplasms with their characteristic appearance on established MRI sequences with and without contrast enhancement.

Abstract
BACKGROUND Primary pancreatic lymphoma is a rare tumour of the pancreas. Data on the role of endoscopic ultrasound guided fine needle aspiration for its diagnosis are scant. AIM To identify the frequency of occurrence, sonographic characteristics and cytological findings that are predictive of primary pancreatic lymphoma. METHODS Pancreatic lymphoma cases were identified by retrospective review of solid pancreatic masses over 10-year period. RESULTS 12/2397 (0.5%) lesions were identified. Patients were predominantly white (92%) and male (58%). Mean largest dimension was 47.5mm and 83.3% were located in the head. The mass appeared heterogeneous in 75% and peripancreatic lymphadenopathy was noted in 58%. None of the patients showed features of chronic pancreatitis or pancreatic ductal dilation. Rapid onsite analysis revealed atypical lymphocytes in 92%. Flow cytometry confirmed diagnosis in 75% of cases. CONCLUSIONS Primary pancreatic lymphoma is encountered in 0.5% of patients undergoing endoscopic ultrasound guided fine needle aspiration. A large heterogeneous mass, in the absence of chronic pancreatitis or pancreatic duct dilation that reveals atypical lymphocytes on fine needle aspiration is suggestive.

Abstract
Contrast-enhanced multiphase CT and dynamic gadolinium-enhanced MR have been validated in the literature as outstanding modalities for the evaluation of pancreatic pathology. In addition to the more frequently seen pancreatic adenocarcinoma, neuroendocrine tumors of the pancreas and cystic lesions such as serous and mucinous cystadenomas and IPMNs, a variety of benign and malignant lesions may occur in the pancreas. The purpose of this pictorial essay is to review the imaging findings of a variety of uncommon, benign and malignant, pancreatic neoplasms.

Abstract
Primary pancreatic lymphoma (PPL), a localized lymphoma in the pancreas, accounts for <0.5% of all pancreatic masses and presents with symptoms favoring the more common adenocarcinoma. It is important to differentiate PPL from adenocarcinoma since treatment and prognosis differ considerably. PPL is potentially curable with chemotherapy, especially if it is diagnosed at early stages. A definitive diagnosis can only be based on histopathological findings. Endoscopic ultrasound-guided fine needle aspiration (EUS-guided FNA) is a reliable, minimally invasive and cost-effective method for this purpose. Even though there are neither typical clinical features nor specific biomarker for the diagnosis of PPL, certain common presentations have been observed which may indicate PPL. We herein present the case of a 43-year-old man who was successfully diagnosed with PPL by EUS-guided FNA. His clinical, laboratory and radiographic findings supported PPL over adenocarcinoma as well. This case demonstrates that high clinical suspicion based on clinical, laboratory and imaging features is critical in PPL diagnosis and management.

Abstract
We report a rare case of pancreas tumor (lymphoma) in a patient with a history of chronic hepatitis C virus (HCV) infection without treatment, with a high viral load (20,199,805 IU/ml). He presented with abdominal pain, jaundice, weight loss and sweating. Computed tomography showed a hypodense mass located in the head of the pancreas, and immunohistochemistry of a specimen obtained by endoscopic ultrasound-guided fine needle aspiration revealed non-Hodgkin's lymphoma of the pancreas, B cell type. An association of HCV infection with pancreatic lymphoma has only been reported rarely in the literature and its clinical significance is uncertain.

Abstract
Hematologic malignancies often involve the pancreas, causing potential diagnostic pitfalls and, rarely, potentially avoidable surgical resection. We review the spectrum of hematologic malignancies involving the pancreas and describe features useful in preoperative distinction from adenocarcinoma. Archived clinical, pathologic, and radiologic data (1965 to present) for hematologic malignancies involving the pancreas were reviewed and compared with the data for 157 surgically resected pancreatic adenocarcinomas. Of 42 cases, 27 (64%) were clinically "suspicious" for hematologic malignancies. Of the remaining 15 cases, 4 patients underwent resection for presumed pancreatic adenocarcinoma. Isolated pancreatic masses proved most difficult to identify clinically. Significant factors in distinguishing hematologic malignancies from adenocarcinoma included history of hematologic malignancy, young age, large tumor size, low CA19-9 level, B symptoms, and lack of jaundice or diabetes mellitus. Various hematologic malignancies involve the pancreas, most commonly diffuse large B-cell lymphoma. Pancreatic masses are usually correctly identified clinically. Preoperative and operative sampling is strongly recommended when hematologic malignancies cannot be excluded.

Abstract
Pancreatic masses can be solid or cystic, benign or malignant. Rapid and accurate diagnosis is essential for optimal management. Clinical presentation and radiological appearance are often inadequate for a definitive diagnosis. Endoscopic ultrasound allows more detailed assessment of the pancreas than traditional imaging techniques.

Abstract
OBJECTIVE To investigate the clinical feature and treatment strategy of primary pancreatic lymphoma. METHODS Thirty-nine cases of primary pancreatic lymphoma reported in China were reviewed retrospectively with their clinical characters, treatment, and outcome, as well as a literature review of worldwide reports. RESULTS The major clinical presentations included discomfort or pain in the upper abdomen and jaundice without specificity. Only 2 cases were identified correctly by computed tomography, and 5 cases obtained a positive finding in a biopsy before operation. Thirty-two patients accepted operation; 13 pancreatoduodenectomy and 6 distal pancreatectomy were performed. Thirty-one patients accepted postoperative chemotherapy. Until now, 26 patients are still alive at a range of 3 to 72 months; 5 patients died at 5 to 24 months after operation. Literature review revealed 85 additional cases of pancreatic lymphoma in English reports. Their diagnosis and treatment methods varied. CONCLUSIONS Primary pancreatic lymphoma was misdiagnosed as pancreatic adenocarcinoma frequently. Fine needle aspiration biopsy is the most valuable method in preoperative diagnosis. The cyclophosphamide, doxorubicin, vincristine, and prednisone scheme was still the most commonly used regimen of chemotherapy. The value of surgery and radiotherapy remains controversial; an operation combining chemotherapy seems to be an appropriate method of treatment for a patient in whom malignancy cannot be ruled out.

Abstract
The purpose of this study was to assess whether dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) can predict response to chemotherapy in advanced pancreatic cancer. DSC-MRI was performed using gradient-echo echo-planar imaging after bolus injection of contrast material. Fifty-four patients with advanced pancreatic cancer who were scheduled for chemotherapy were enrolled. ΔR2* was calculated using semi-automated computer analysis capable of tracking moving lesions during DSC-MRI. Pre-treatment maximum ΔR2* and clinical factors including gender, age, tumor stage (UICC III/IV), initial tumor size, and chemotherapy regimen were compared between patients with progressive disease and patients with stable disease as was determined at 3-month follow-up, and between patients with progressive disease and patients with stable disease as was determined at 6-month follow-up. Receiver operating characteristic (ROC) analysis and the Kaplan-Meier method with log-rank test were used to assess the relationship between the pre-treatment maximum ΔR2* and early progression (i.e. at 3-month follow-up). The pre-treatment maximum ΔR2* of patients with disease progression at 3-month follow-up (10.68 ± 3.88 s(-1)) was significantly different (p < 0.01) from that of patients with stable disease at 3-month follow-up (6.94 ± 3.12 s(-1)). Pre-treatment maximum ΔR2* of patients with disease progression at 6-month follow-up was not significantly different from that of patients with stable disease at 6-month follow-up, although a trend was noted (p = 0.08). Pre-treatment clinical factors were not significantly different between progressive and stable patients at 3- and 6-month follow-up. Tumor progression rate was significantly higher in patients with a higher pre-treatment maximum ΔR2* than in those with a lower pre-treatment maximum ΔR2* (median progression time, 38 vs 138 days, p < 0.01, using a cut-off value of 8.13 s(-1) as determined by ROC analysis). In conclusion, DSC-MRI may predict early progression in patients with advanced pancreatic cancer undergoing chemotherapy.

Abstract
Primary pancreatic lymphoma (PPL) is a rare disease that is difficult to diagnose preoperatively. We describe the youngest case of PPL treated by surgical excision and chemotherapy. A 16-year-old male presented with abdominal pain and jaundice. Abdominal computed tomography showed a 3.0 × 4.5 cm homogeneously enhanced mass localized between the inferior vena cava and pancreatic head; the common pancreatic duct was dilated and the common bile duct was stenosed. Magnetic resonance imaging findings showed a 4.5 cm tumor localized between the inferior vena cava and pancreatic head with low signal intensity on T1W images and high intensity on T2W images, which enhanced inhomogeneously. Endoscopic retrograde cholangiopancreatography findings were compatible with smooth stenosis of the common bile duct. He was diagnosed as pancreatitis secondary to pancreatic tumor and pylorus-preserving pancreaticoduodenectomy was performed. Postoperative diagnosis was PPL and chemotherapy was performed. After 4 years of treatment he has no signs of recurrence.

Abstract
BACKGROUND AND AIM The use of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) +/- flow cytometry (FC) for the diagnosis of suspected lymphoma remains controversial. We report our experience and diagnostic yield for EUS +/- FC for suspected lymphoma. METHODS Databases were queried for those who underwent EUS-FNA +/- FC for suspected lymphoma. Hospital charts were reviewed to confirm the final cytological diagnosis, follow up and FC results if obtained. The final diagnosis was confirmed by the results of EUS-FNA +/- FC, other biopsy and/or follow up. RESULTS In total, 54 patients underwent EUS-FNA of 72 lesions. The final diagnosis of lymphoma was made in 38 of the 54 (70%) patients, and 33 of the 54 (61%) patients relied on EUS-FNA. Cytopathology in 41 patients using EUS-FNA + FC showed lymphoma in 24 patients, atypical lymphoid cells in six and reactive lymph node in 11. In 9 of the 24 with lymphoma by EUS + FC, the diagnosis was confirmed by another diagnostic modality, like surgery, bone marrow biopsy and computed tomography-guided biopsy. Of the six with atypical lymphoid cells, additional diagnostic methods confirmed lymphoma in three. The remaining 13 of the 54 patients underwent EUS-FNA without FC due to insufficient sample (n = 5) or operator choice (n = 8). Cytopathology in these 13 patients without FC showed lymphoma (9), atypical lymphoid cells (3) and reactive node (1). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of EUS-FNA for lymphoma in all 54 patients ranged from 80% to 87%, 92% to 93%, 97%, 60% to 75% and 83% to 89%, respectively. CONCLUSIONS EUS-FNA is sensitive and specific for the diagnosis of suspected lymphoma. Confirmatory or further testing should be performed when EUS-FNA with or without FC is indeterminate and or non-diagnostic.

Abstract
The purpose of this study was to determine if the apparent diffusion coefficient (ADC) on diffusion-weighted MRI could predict the response of patients with advanced pancreatic cancer to chemotherapy. Diffusion-weighted MRI was performed in 63 consecutive patients with advanced pancreatic cancer who were subsequently treated with chemotherapy. The ADC values of the primary tumour with a middle b-value (400 s mm(-2)) and a high b-value (1000 s mm(-2)) were determined; cystic or necrotic components were avoided. The patients were classified into two groups: (i) those with progressive disease and (ii) those who were stable 3 months and 6 months after initial treatment. The groups were compared with respect to the ADC and clinical factors, including gender, age, Union International Contre le Cancer (UICC ) stage, initial tumour size and chemotherapy agents used. Local tumour progression rates were evaluated using the Kaplan-Meier method. The middle b-value ADC of the pancreatic cancers ranged from 0.93-2.42 x10(-3) mm(2) s(-1) (mean, 1.50 x10(-3) mm(2) s(-1)), and the high b-value ADC ranged from 0.72-1.88 x10(-3) mm(2) s(-1) (mean, 1.20 x10(-3) mm(2) s(-1)). The high b-value ADC was significantly different between the progressive and stable groups at 3 months' and 6 months' follow-up (p = 0.03 and p = 0.04, respectively). The rate of tumour progression was significantly higher in those with a lower high b-value ADC than in those with a higher b-value ADC (median progression time, 140 days vs 182 days; p = 0.01). In conclusion, a lower high b-value ADC in patients with advanced pancreatic cancer may be predictive of early progression in chemotherapy-treated patients.

Abstract
AIM: To investigate the value of clinical manifestations and ultrasound examination in the differential diagnosis of pancreatic lymphoma and pancreatic cancer.
METHODS: The clinical and ultrasonic characteristics of 12 cases of pancreatic lymphoma and 30 cases of pancreatic cancer were retrospectively analyzed.
RESULTS: Statistically significant differences were found in the course of disease, back pain, jaundice, carcino-embryonic antigen (CEA) and CA19-9 increase, palpable abdominal lump, superficial lymph node enlargement, fever and night sweats, lesion size, bile duct expansion, pancreatic duct expansion, vascular involvement, retroperitoneal (below the renal vein level) lymph node enlargement, and intrahepatic metastasis between pancreatic lymphoma and pancreatic cancer. There were no significant differences in age of onset, gender ratio, weight loss, nausea and vomiting, lesion position, the echo of the lesion, and the blood flow of the lesion.
CONCLUSION: Pancreatic lymphoma should be considered for patients with long lasting symptoms, superficial lymph node enlargement, palpable abdominal lump, fever and night sweats, relatively large lesions, and retroperitoneal (below the level of the renal vein) lymph node enlargement. A diagnosis of pancreatic cancer should be considered more likely in the patients with relatively short disease course, jaundice, back pain, CEA and CA19-9 increase, relatively small lesions, bile duct expansion, obvious pancreatic duct expansion, peripheral vascular wrapping and involvement, or intrahepatic metastases.

Abstract
The case concerns a 55-year-old Japanese man with multiple pancreatic tumors that were incidentally detected by ultrasonography (US) in a routine medical examination. He consulted a doctor since either neuroendocrine tumors or metastases of small-cell lung carcinoma were suspected, because he had an abnormal shadow in the lung. Then he was transferred to our hospital. Imaging studies showed multiple pancreatic tumors of 3.0-cm diameter in the head, 1.0 cm in the body and 1.5 cm in the tail, respectively. Specimen by endoscopic ultrasonography fine-needle aspiration cytology (EUS-FNAC) revealed numerous B-cell lymphocytes, but a definite diagnosis of malignant lymphoma could not be obtained. Therefore, a segmental pancreatic body resection was performed to clarify the features of the tumor for appropriate therapy. Consequently, the final diagnosis was obtained as a low-grade B-cell lymphoma having a lymphoepithelial lesion, which indicated mucosa-associated lymphoid tissue (MALT) lymphoma. Radiation therapy with 31 Gy successfully resulted in complete remission. We report here for the first time on primary pancreatic low-grade MALT lymphoma presenting with multiple pancreatic masses.
