primary pancreatic lymphoma is a rare extranodal manifestation of any histopathologic subtype of b cell non-hodgkin's lymphoma that predominantly involves the pancreas. it comprises less than 0.2% of pancreatic malignancies and less than 0.7% of non-hodgkin's lymphomas. this lymphoma is almost never suspected clinically. it is usually diagnosed by surgical exploration for suspected ad...

lymphomas are solid tumors of immune system and non-hodgkin lymphomas (nhl) is the most prevalent lymphomas; with wide ranges of histological and clinical features, it is so difficult to identify them. herein, various bioinformatics tools (such as gene differential expressions, epigenetics and protein analysis) employed to find new treatment approach for nhl based on gene expression variation b...

introduction: a study was made conserning 142 patients who were suffering from gastrointestinal lymphoma, were seen at the department of hematology and oncology, esfahan medical school, during the period 1982-2002. method: all patients had laparotomy, and biopsy of the site lesion. histopathological subtypes were done in the international working formulation. stage groupings were done applying ...

neurolymphomatosis is a rare manifestation of non-hodgkin lymphoma characterized by infiltration of peripheral nerves, nerve roots, plexus and cranial nerves by malignant lymphocytes. this report presents positron emission tomography/computed tomography (pet/ct)imaging with 2-deoxy-2-18f-fluoro-d-glucose (18f-fdg) in 3 cases of non-hodgkin lymphoma with nerve infiltration, including one newly d...

a male patient with acute renal failure (arf) due to large b-cell non-hodgkin lymphoma infiltration of kidney is presented. the diagnosis was suspected because of coincidence of arf and tumor lysis syndrome non-responsive to conservative renal therapies. a renal biopsy confirmed diagnosis and appropriate chemotherapy led to complete improvement of renal function.

background: lymphomas are a group of malignancies affecting b, t and nk cells. cox-2 enzyme is one of the known inflammatory factors which increase in the inflammation process. increase in cox-2 expression inhibits apoptosis and increases tumor cells invasion and angiogenesis. increase in the cox-2 gene expression is seen in a group of cancers .specific cox-2 inhibition also can be beneficial i...

despite multiple published studies reporting result of salvage regimens for relapsed and refractory hodgkin's lymphoma, there are no comparisons of different combinations.a total of 44 patients identified with refractory or relapsed hodgkin's lymphoma were considered eligible for this study. the patients were randomly divided into two groups of 22, one of which were treated with gdp regimen (ge...

Background: The clinical presentation of non-Hodgkin lymphoma (NHL) varies tremendously depending upon the type of lymphoma and the areas of involvement. NHL can rarely present as an abdominal mass compressing the inferior vena cava. The clinical presentation due to obstruction of inferior vena cava has often been called the inferior vena cava syndrome (IVCS). It can present acutely or chronica...

Introduction: Central mucoepidermoid carcinoma (CMEC) is a rare primary intraosseous bony lesion. The mandible is more commonly affected than the maxilla. CMEC is frequently misdiagnosed radiographically and clinically as a benign odontogenic tumor or cyst. Case Presentation: We present a rare case with a secondary malignant neoplasm. A male patient was initially diagnosed with B-cell non-Hodg...

OBJECTIVE Classical Hodgkin lymphoma shows a peak incidence at 15-35 years, and a second peak in elderly patients; however, pathological characteristics of elderly patients with classical Hodgkin lymphoma have not been analyzed enough. METHODS In a total of 154 patients with classical Hodgkin lymphoma, we analyzed the clinicopathological characteristics of classical Hodgkin lymphoma patients ...
