A patient with S#{233}zary syndrome presented with disease limited to the skin and circulating abnormal lymphocytes but subsequently developed a diffuse undifferentiated lymphoma. Malignant cells from a lymph node effaced with the morphologically undifferentiated lymphoma were characterized as being of thymus-derived (T cell) origin. We have previously shown that circulating malignant lymphocyt...

Non-Hodgkin ́s lymphoma is very diverse and includes over 60 specific lymphoma types. They are grouped by their aggressiveness. Some of them grow and spread slowly, and are called indolent lymphomas. These lymphomas are less lifethreatening, but they are much harder to cure definitively. Other lymphomas tend to grow more rapidly and aggressively and spread quickly through the body. They can even...

A FEW years ago, it became clear, in the progress of experimental tumor immunology'-7 that all virusinduced tumors carry a common, group-specific transplantation antigen, capable of inducing rejection reactions in syngeneic hosts. The question arose whether it would be possible to utilize this fact for the search after possibly similar, virally determined transplantation antigens in tumors of u...

background and objectives: human herpes 6 virus (hhv-6) could remain latent and chronic in the host cells after primary infection. hhv-6 genome encodes certain trans activation proteins which may results in development of malignantlymphoma. the association of human herpes six virus (hhv-6) infection and hodgkin and non-hodgkin lymphomas is strongly supported by epidemiological studies. the aim ...

OBJECTIVE The aim of the study was to investigate the utility of intravoxel incoherent motion (IVIM) diffusion-weighted magnetic resonance imaging (DWI) for differentiating nasopharyngeal carcinoma (NPC) from lymphoma. METHODS Intravoxel incoherent motion-based parameters including the apparent diffusion coefficient (ADC), pure diffusion coefficient (D), pseudodiffusion coefficient (D*), perf...

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 Childrenchr('39')s Hospital, affiliated to Babol University of medical sciences (nort...
