AIMS To determine the spectrum of renal lesions in patients with kidney involvement in non-Hodgkin's lymphoma (NHL) by renal biopsy. METHODS The clinical features and histological findings at the time of the renal biopsy were assessed for each patient. RESULTS We identified 20 patients with NHL and renal involvement, and the diagnosis of NHL was established following the kidney biopsy in 18...

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...

ocular involvement in lymphoma is a relatively rare condition that can result from a primary intraocular lymphoma or an intraocular manifestation of systemic lymphoma. lymphoma manifestations frequently masquerade as other more benign intraocular conditions including allergic or infectious conjunctivitis, uveitis, multiple evanescent white dot syndrome, acute retinal necrosis, or herpetic retin...

Peripheral T-cell lymphomas are a group of heterogeneous disorders and according to WHO classification, are categorized into nodal and extranodal forms. NK/T-cell lymphoma, nasal type, is a subtype of extranodal peripheral T-cell lymphoma and commonly presents as a midfacial destructive lesion. This disorder is more prevalent in Asia and South America and has a strong association with Epstein B...

BACKGROUND AND PURPOSE Squamous cell carcinoma (SCC) and lymphoma are common malignant tumors of the head and neck. The purpose of this study was to determine whether the apparent diffusion coefficient (ADC) in line scan diffusion-weighted imaging (LSDWI) is useful for distinguishing between SCC and lymphoma of the head and neck. METHODS LSDWI was prospectively performed in 39 patients with S...

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 ...

In addition to intrinsic genetic alterations, the effects of the extrinsic microenvironment also play a pathological role in cancer development. Altered chemokine/cytokine networks in the tumor microenvironment may contribute to the dysregulation of cellular functions in cancer cells. Anaplastic large cell lymphoma (ALCL) is an aggressive T-cell lymphoma caused by abnormal expression of anaplas...

OBJECTIVE To evaluate the use of high-dose sequential chemotherapy in a Brazilian population. METHODS High-dose cyclophosphamide followed by autologous hematopoietic stem cell transplantation is an effective and feasible therapy for refractory/relapsed lymphomas; this regimen has never before been evaluated in a Brazilian population. All patients (106 with high-grade non-Hodgkin lymphoma and ...

Extranodal marginal zone B-cell lymphoma of the mucosa associated lymphoid tissue (MALT-lymphoma) is mot commonly diagnosed in stomach (30%–35%), but exceedingly rare intestinal tract (2%). Consequently, data on this special subgroup are scarce. Out 484 patients with MALt-lymphoma and treated at our institution from 1999 to 2020, 42 (11%) had involvement (24 primary 18 secondary) were restrospe...

Co-expression modules are groups of genes with highly correlated expression patterns. In cancer, differences in module activity potentially represent the heterogeneity of phenotypes important in carcinogenesis, progression, or treatment response. To find gene expression modules active in breast cancer subpopulations, we assembled 72 breast cancer-related gene expression datasets containing ∼5,7...
