Pancreatology, 2002
We report the case of a 33-year-old man who presented with a large B-cell non Hodgkin's lymphoma presenting as acute pancreatitis. Abdominal CT showed diffuse swelling of the pancreas, with two distinct masses in the corpus and the tail. Thoracic CT showed a markedly enlarged mediastinum, with a voluminous mass in the middle mediastinum. Direct biopsy of this mass revealed a large B-cell lymphoma. Chemotherapy followed by peripheral blood cell autotransplantation led to complete disappearance of the pancreatic and mediastinal masses. Fatty diarrhea occurred after chemotherapy, probably owing to gland destruction by lymphomatous infiltration. Twenty-six months later, the patient is disease-free but continues to require pancreatic enzyme supplements.
Primary pancreatic diffuse large B-cell lymphoma: Report of two cases
World Chinese Journal of Digestology, 2017
Primary pancreatic lymphoma (PPL) is an uncommon neoplasm which can clinicoradiologically mimic carcinoma. But the management of these patients differs from that of a carcinoma. Endoscopic ultrasound (EUS) guided fine-needle aspiration (FNA) serves as a potential tool to identify pancreatic lymphomas and thus prevent an invasive diagnostic test. This case report describes the presentation and diagnosis of primary pancreatic lymphoma. A 37-year-old female presented with nausea, vomiting with signs of icterus and elevated liver function test and Bilirubin. Abdominal computed tomography (CT) revealed a hypodense lesion in the head of the pancreas. EUS guided FNA was performed and cytological material was collected. The lesion was diagnosed as Non-Hodgkin Lymphoma (NHL) and subtyped as diffuse large B-cell lymphoma-germinal centre (DLBCL-GCB) base on immunohistochemistry on cell block. The patient was started on rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (RCHOP) regimen. EUS guided FNA along with ROSE, cell bock, and immunocytochemistry helps in the diagnosis of primary pancreatic lymphoma.
Primary Gastric Lymphoma (Diffuse Large B Cell Type)
2021
The most frequent extra-nodal site of lymphoma is gastric lymphoma. The bulk of such lesions are extra nodal marginal zone B mucosal cell lymphoma correlated with lymphoid tissue (MALT) type or diffuse lymphoma of large B cells. We are reporting a case of diffuse major B-Cellular gastric lymphoma, which at first showed indigestion, abdominal heaviness, nausea and widespread weakness with 3-4 months of weight loss. In the antropyloric region and distal portion of lesser curvature of stomach suggestive of aetiology of cancer, the CT abdomen shows circumferential wall thickening. DLBCL has been confirmed by HPE and IHC. The neoplasm entered serosa and was found to have adherence to the pancreatic capsule in stage IIE of gastric lymphoma. Following the staging, treatment with an R-CHOP regimen (rituximab, cyclophosphamide, oncovin (vincristine), hydroxydaunorubicin, and prednisone) was done.
An Atypical Case of Primary Gastric Lymphoma
Scholars Journal of Medical Case Reports, 2016
We report a case of a fifty-two-year old gentleman who presented with a history of early satiety after meals altered bowel habits for 1 month and fever for 2 weeks. On local examination, an intra-abdominal, non-tender, variegated swelling was found extending from left hypochondrium to the epigastric region. Contrast enhanced CT scan showed a heterogeneous mass (11 cm x 11 cm) at left upper quadrant, medial to spleen, compressing the stomach, ?Neoplastic lesion. Exploratory laparotomy found a huge irregular mass involving spleen, tail of pancreas, gerota's fascia and greater curvature of stomach, having adhesion with diaphragm and omentum, but without any enlarged lymph nodes. En-bloc excision of mass along with spleen, tail of pancreas, and a sleeve of stomach including the greater curvature was preformed. Subsequently, histopathology and immunohistochemistry confirmed it to be a case of Diffuse Large B-Cell Lymphoma of stomach (DLBCL).The rarity of the diagnosis along with its nature of presentation, and absence of several characteristic features make this case an interesting one.
Primary pancreatic lymphoma: A rare cause of pancreatic mass
Oncology Letters, 2015
Primary pancreatic lymphoma (PPL) is a rare entity, most likely to be clinically misdiagnosed as pancreatic cancer. The cure rate of PPL is higher compared with that of pancreatic adenocarcinoma. This is the case report of a 57-year-old male patient who was hospitalized with complaints of abdominal pain, weight loss and jaundice. The radiological evaluation revealed a pancreatic head mass and, following endoscopic ultrasound-guided fine-needle aspiration biopsy, the tumor was diagnosed as diffuse large B-cell lymphoma. The final diagnosis was PPL, and the patient went into remission after receiving three cycles of treatment with rituximab, doxorubicin, cyclophosphamide, vincristine and prednisolone (R-CHOP regimen). Therefore, PPL should be considered in the differential diagnosis of pancreatic masses and its management differs from that of other types of pancreatic tumor.
Primary Pancreatic lymphoma: a rare clinical entity
BMJ Case Reports
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 m...
B-cell lymphoma presenting as acute pancreatitis symptoms in a child
Iranian journal of pediatric hematology and oncology, 2020
Lymphoma which has a wide range of manifestations is the third malignancy in pediatrics. Nearly, 50% of patients have extranodal involvement. Pancreas can be affected secondarily more than primarily. A 10-year-old boy with recurrent abdominal pain in the epigastric region for six weeks was referred to Amirkola Children's Hospital, affiliated to Babol University of medical sciences (north of Iran). The patient was icteric with elevated levels of amylase and lipase. A hypoechoic mass near the head of the pancreas was detected by ultrasound examination. Pathology of stomach polyps revealed small blue round-cell tumor compatible with a lymphoma. In children with acute pancreatitis symptoms and palpable abdominal mass, the non-Hodgkin lymphomas (NHL) should be considered as an important, though rare possible cause.
Primary Gastric Lymphoma: Case Report with Review of Literature
2014
Stomach is the most common site of lymphoma in gastrointestinal tract, which can be either primary or secondary to lymphoma at other sites. Mucosa associated lymphoid tissue (MALT) lymphomas and diffuse large B cell lymphomas (DLBCL) are commonly encountered in stomach. Most of the gastric lymphomas are found secondary to chronic inflammation induced by Helicobacter pylori infection. Primary lymphomas of stomach carry a better prognosis and hence correct diagnosis is important. We report a case of primary gastric lymphoma of DLBCL type which was negative for H. pylori infection, in a 45 year old male.
