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...
BACKGROUND Cyclin D1-negative mantle cell lymphoma is difficult to distinguish from other small B-cell lymphomas. The clinical and pathological characteristics of patients with this form of lymphoma have not been well defined. Overexpression of the transcription factor SOX11 has been observed in conventional mantle cell lymphoma. The aim of this study was to determine whether this gene is expre...
This case report describes a low-grade malignant B-cell lymphoma (lymphocytic lymphoma) in 14-year-old mixed breed cat, diagnosed by bronchoscopy and diagnostic imaging (radiography, ultrasound computed tomography). The patient was treated with surgery, postoperative complications included blindness severe mycoplasma infection of the thoracic cavity, which using vacuum-assisted closure device. ...
Clinical trials of immunotherapy in mantle cell lymphoma have not yet delivered desirable results, partly because of the inhibitory machinery of the tumor and its microenvironment. Here we investigated the role of B7-H1, a member of the B7 family of co-stimulatory/co-inhibitory ligands, in mantle cell lymphoma-mediated immunosuppression. Allogeneic CD3(+), CD4(+) and CD8(+) T cells were purifie...
In the last years several borderline B-cell lymphoid proliferations have been recognized that lie at interface between benign and malignant. These lesions can be divided in two groups; those considered precursor of well malignancies group indolent lymphomas with limited potential for progression. Precursor are monoclonal share many genetic features their malignant counterpart. The first lesion ...

vertebra plana is a radiological diagnosis that indicates complete compression of the vertebral body.(1,2) this condition was reported in langerhans cell histiocytosis including eosino-philic granuloma,(3, 12) ewing's sarcoma,(2,13,14) tuberculosis,(15,16) vertebral osteomyelitis,(17) aseptic necrosis,(18) aneurysmal bone cyst,(19) osteosarcoma,(20) neuroblastoma,(21) acute leu-kemia,(22) rhabd...
we present a woman referred with underlying non-hodgkin's lymphoma (nhl) masquerading clinically with guillain-barré syndrome (gbs) like syndrome. at first evaluation, chest ct-scan along with brain and whole spine mri were normal. electrodiagnostic studies were in favor of acute generalized polyradiculoneuropathy. laboratory evaluation revealed hypoglycorrhachia. she treated with plasmapheresi...
Primary breast lymphomas (PBL) are an exceptionally rare form of extranodal non-Hodgkin lymphoma (NHL), occurring in less than 0.5% all malignancies.1 T-cell (TCL) is even rarer entity, accounting for only 6% lymphomas. It has aggressive but poorly understood clinical course, and non-specific features that can mimic inflammatory carcinoma (oedema, skin changes mastalgia).1 Currently, there no s...
undifferentiated nasopharyngeal corcinoma is frequently misdiagnosed as large cell malignant lymphoma. the aim of this study is to evaluate the diagnostic role of immunohistochemistry and electron microscopy in this tumor. 81 cases of nasopharyngeal carcinoma were studied. patients ranged from 9-90 years in age (mean: 48.5 years). the age incidence curve was bimodal with two peaks in 2-3 and 5-...
