A 15-year-old young man presented to the emergency department with a 3-week history of sharp left-sided chest pain, shortness of breath on exertion, and a low-grade intermittent fever. Chest radiograph revealed increased density in the upper left lobe, thus he was treated with antibiotics for query pneumonia. Although his fever subsided, the patient continued to have chest pain, and subsequentl...

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 54-year-old Caucasian woman was admitted due to persistent febrile syndrome, sweating and abdominal pain. Fever marked the onset of the patient’s medical history 10 years earlier. The physical examination revealed normal findings. Laboratory data showed normal white blood cell count, mild microcytic anaemia with a normal reticulocyte count, important inflammatory syndrome (C-reactive protein ...

lymphomas are classified as hodgkin’s and non-hodgkin’s lymphomas (hl nhl) nhl being further sub-divided into b, t and null cell categories on the basis of who classification. with a few exceptions worldwide, b-nhl are more common, accounting approximately 80-85% of all cases of nhl compared to t-nhl, which accounts for about 10-15% of all nhl cases. the incidence of nhl has shown a steady incr...

BACKGROUND Cyclooxygenase (cox) is the rate-limiting enzyme, which catalyzes the conversion of arachidonic acid into prostaglandins and contributes to the inflammatory process. Cyclooxygenase-2 (cox-2), which is one of the two isoforms, plays a role in tumor progression and carcinogenesis. p53 contributes to apoptosis, DNA renewal and cell cycle. Studies concerning the relationship of cox-2 and...

background and objectives: classic hodgkin lymphoma (chl), anaplastic large cell lymphoma (alcl) and some cases of diffuse large b cell lymphoma (dlbcl) have overlapping morphologic features. since they all represent distinct clinico-pathologic entities, we explored the differential diagnostic impact of immunophenotyping to discriminate between them. materials and methods: we included 61 cases ...

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...
