One of the rare variants of extranodal large B-cell lymphoma is intravascular large B-cell lymphoma (IVLBCL). Characteristics of IVLBCL include intraluminal selective proliferation of atypical lymphoid cells in small to medium-sized vessels. The etiologic of IVLBCL is unknown, but due to the growth pattern of this tumor, it is speculated that IVLBCL is caused by a defect in homing receptor of t...

Currently lymphoma is mainly treated with combination chemotherapy, hematopoietic stem cell transplantation, immunotherapy, and new targeted therapy, but treatment-related drug resistance, recurrence, extranodal central infiltration, leukemic transformation are still clinical problems that need to be solved urgently. Studies have shown cytokines expressed varying degrees in patients, which sign...

Secondary pancreatic involvement can be seen up to 30% of advance staged non-Hodgkin’s lymphoma cases, but primary lymphomas constitute only 1% extranodal lymphomas. Furthermore, 0.2% the space-occupying lesions are lymphomas, which usually present as a mass in head pancreas with nonspecific symptoms. Therefore, should considered differential diagnosis solid lesions. Herein, we report two cases...

Posttransplant lymphoproliferative disorder (PTLD) is a well-documented complication that arises as a result of immunosuppression in the setting of solid organ or bone marrow transplantation. The disorder may be subtle and/or extranodal. We report a patient with extranodal lymphoma following kidney transplantation who had successful treatment with surgery and chemotherapy.

Extranodal natural killer (NK)/T-cell lymphoma is a very rare and aggressive disease characterized histopathologically by an Epstein-Barr virus (EBV)-positive atypical lymphoid cytotoxic infiltrate, extensive vascular destruction, and prominent tissue necrosis. It commonly shows cutaneous lesions that primarily or secondarily mimic cellulitis at the primary site. We report on a very rare case o...

Aim: To evaluate the clinical manifestations, histopathologic composition, and demographic characteristics of lymphomas presented in head neck.
 Materials Methods: Records subjects who had a diagnosis lymphoma by an otolaryngology clinic tertiary referral hospital between May 2007 July 2017 were reviewed. Demographic features data regarding histopathology, radiology, presentation evaluated...

Mantle cell lymphoma (MCL) is a relatively rare subgroup of non-Hodgkin's lymphoma that is characterized by an aggressive and severe disease course with frequent involvement of regional lymph nodes and/or early metastasis. Because most cases of MCL are diagnosed in the advanced stages, clinical data on extranodal or early stage MCL is lacking, and MCL that is both extranodal and diagnosed durin...

Mucosa-associated lymphoid tissue (MALT) lymphoma is an extranodal indolent lymphoma with histopatholigic features similar to those of marginal zone B-cell lymphomas. Primary breast MALT lymphomas were first described by Lamovec and Jancar as a low-grade B-cell lymphoma in 1987. Herein, a case is presented of a patient with primary MALT lymphoma of the breast. Issues in diagnosis and breast-con...

Burkitt lymphoma (BL), an aggressive non-Hodgkin lymphoma, usually presents with large extranodal masses involving jaw bones, intestines and central nervous system. There are 3 main types of BL: endemic, sporadic, and immunodeficiency variant. Although each variant frequently involves extranodal site, cutaneous involvement is distinctly rare. Most of the previously reported cases with cutaneous...
