A case of primary malignant non-Hodgkin's lymphoma of the breast is reported. This is the first well-documented case of breast lymphoma in our institution and also in Iran. The diagnosis of primary breast lymphoma requires the presence of lymphomatous infiltration in close ass, tissue in patients with neither previous lymphoma nor concurrent lymphoma in another site. There is no definite cl...

The proteasome inhibitor bortezomib (PS-341/Velcade) is used for the treatment of relapsed and refractory multiple myeloma and mantle-cell lymphoma. We recently reported its therapeutic potential against natural killer (NK)-cell neoplasms. Here, we investigated the molecular mechanisms of bortezomib-induced cell death in NK lymphoma cells. NK lymphoma cell lines (SNK-6 and NK-YS) and primary cu...

protein losing enteropathy (ple) as an initial finding of lymphoma, is extremely rare in childhood. we describe clinical and pathological features of an unusual case of gastrointestinal lymphoma presented with ple as a sole manifestation. differential diagnosis in children presenting with ple is critical because early diagnosis and treatment are important for survival in patients with lymphoma.

non hodgkin lymphoma (nhl) constitutes 5% of all head & neck cancer. the incidence of it has been increased over the last four decades. one of main characteristic of nhl is extranodal presentation that has different pattern in various part of world. a retrospective was designed in a tertiary referral center. it has been done between january 1996 and march 2006. all clinical and pathological cha...

High-resolution resonance-photoemission spectroscopy has been performed on the Ce1-xLaxRhAs (0≤x≤0.05) single crystal to elucidate a collapse of the energy gap in the Kondo semiconductor CeRhAs by La substitution. With increasing x, the spectral intensity of the Ce 4f derived states near the Fermi level decreases and new 4f derived spectral feature appears at a higher binding energy. The Rh 4d-...

T-cell lymphomas are a type of non-Hodgkin lymphoma that arise from specific immune system cells termed T lymphocytes. This relatively rare lymphoma is generally classified as either cutaneous T-cell lymphoma (CTCL) or peripheral T-cell lymphoma (PTCL). While CTCL initially manifests as skin lesions before metastasizing to other organs, PTCL may occur both systemically or cutaneously. The most ...

Introduction: Burkitt lymphoma is an aggressive subtype of Hodgkin lymphoma with a doubling time of 25 hours. It is characterized by a MYC gene coding alteration which results from a translocation of chromosome 8 on the MYC gene locus and immunoglobulin heavy-chain locus (IGH) on chromosome 14. Even though HIV infection is associated to an increased risk of Burkitt lymphoma, th...
