the occurrence of langerhans cell histiocytosis (lch) in a patient with lymphoma is an indication of a probable relationship between them. the two conditions have similarities both clinically and histopathologically. occurrence of these two conditions in the same patient, particularly not simultaneously, is rare. according to different management and treatment of these conditions, exact histopa...

common radiologic features of lymphoma in lung are included: adenopathy, pleural effusion, multiple or solitary masses and diffuse infiltration. we want to present a 28y/o male with pulmonary hodgkin lymphoma with a rare radiographic pattern and distinct histologic description that at first misdiagnosed as pulmonary tuberculosis but eventually lung biopsy confirmed diagnosis of pulmonary hodgki...

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 ...

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...

non hodgkin lymphomas (nhl) are nodal or extra nodal monoclonal infiltrations by malignant lymphoid cells (b lymphocytes in 80% of cases), which are distinguished as indolent or aggressive forms. according to the heterogeneity of lymphoid cells and their ubiquitous anatomical distribution, these disorders can develop in any organ and have very heterogeneous clinical expressions, but they are us...

BACKGROUND Hodgkin lymphoma is uncommon in the U.S. general population; however, Hodgkin lymphoma risk is elevated in people with human immunodeficiency virus (HIV) infection. Thus, despite the low HIV prevalence in the United States, the HIV epidemic may have contributed substantially to the general population burden of Hodgkin lymphoma. METHODS We used data from 14 U.S. cancer registries in...

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 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...
