In an area of lymphoma classification still being defined, marginal-zone lymphomas have distinctive immunohistochemical and cytogenetic features that distinguish them from mantle-cell and follicular lymphomas. There are three subtypes: the extranodal mucosa-associated lymphoid tissue (MALT) lymphomas, the nodal monocytoid B-cell (MBCL) lymphomas, and the splenic marginal-zone lymphomas. The MAL...

Triple hit lymphomas (THL) comprise a rare, heterogenous group of and like many B-cell lymphomas, chromosomal translocations are biologic diagnostic hallmarks disease. Traditionally referred to as subset double (DHL) in literature, THLs characteristically involve rearrangements c-MYC, BCL-2, BCL-6 oncogenes. Many case series high-grade lymphoma, especially MYC/BCL2 have been described the but r...

Follicular lymphoma is a type of systemic lymphomas which constitutes approximately 30-35% all Non-Hodgkin lymphomas. It typically presents itself in the form generalized lymphadenopathy, hepatomegaly, splenomegaly and bone marrow involvement. Cutaneous involvement follicular generally appears as skin-coloured to red, violaceous papules or nodules most commonly involving scalp, trunk head&n...

background: since there has been no published report on the impact of permanent canines in shiraz population, this study was conducted to investigate the prevalence and the location of the impacted permanent canines in patients referred to the department of radiology of shiraz dental school in 2012. materials and methods: this was an analytic cross-sectional study on 1012 panoramic radiographs....

Mouse lymphomas induced by the Moloney agent were strongly antigenic in isologous hosts, as indicated by transplantation and serologic tests. Specific transplantation resistance was established by pretreattnent of the recipients with homografts of other Moloney lymphomas, small isografts of the same lymphoma, or virus-containing lymphoma homogenates. Extensive cross-resistance was demonstrated ...

BACKGROUND AND AIM: Tooth extraction as a part of orthodontic treatment plan to create space for leveling and aligning teeth or causing tooth movement leads to changes in arch width and length. The outcome of these changes is important for the clinicians and affects the treatment and retention plans. Despite some previous studies, data in this regard are still scarce and further investigation i...

The overlapping features of malignant lymphomas create a diagnostic "grey zone" , and lead to the invention of "grey zone lymphomas". There are several major grey zone lymphomas: 1) Lymphomas with overlapping features of Hodgkin lymphoma and large B-cell lymphoma; 2) Lymphomas with overlapping features of Burkitt lymphoma and diffuse large B-cell lymphoma; 3) Lymphomas with overlapping features...
