Cases of lymphocytic monoclonal B-cell proliferation such as non-Hodgkin’s lymphomas have been reported in chronically hepatitis C virus (HCV)-infected patients. Lymphomas of the mucosa-associated lymphoid tissue (MALT) type are due to monoclonal proliferation of B cells showing characteristic histopathological features of MALT. Luppi et al1 recently reported an unexpectedly high prevalence of ...

To the Editor: Primary central nervous system lymphoma (PCNSL) is defined as lymphoma confined to the brain, spinal cord, eye, or leptomeninges. Ocular involvement can be detected in about 20% of PCNSL patients with primary vitreous retinal lymphoma (PVRL), which is generally a high‐grade diffuse large B‐cell lymphoma, being the most common subtype. The incidence of PVRL is extremely low, with ...

Rituximab, a chimeric antibody that targets CD20(+) B cells, produces a 48% response rate in patients with refractory low-grade non-Hodgkin lymphoma. In this phase II trial, patients with low-grade non-Hodgkin lymphoma who had previously received no systemic therapy were treated with rituximab, 375 mg/m(2), administered by IV infusion for 4 consecutive weeks. Patients with objective response or...

Primary nonHodgkin's lymphoma (NHL) occurs in both nodal and extranodal sites. Lymphoma arising in mammary tissue is rare. The majority are of B-cell origin, while a few case studies of T-cell lymphomas of the breast have been reported. The clinical and histologic features of a 74-year-old female diagnosed with T-cell mammary lymphoma are reported, as well as her treatment course and follow-up....

BACKGROUND/AIM Lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) of the stomach usually occurs as a consequence of Helicobacter pylori (H. pylori) infection. The aim of this study was to investigate the long-term effect of treatment of low-grade gastric MALT lymphoma with the H. pylori eradication method. METHODS In the period 2002-2012 in 20 patients with dyspepsia, mean age 55.1...

Twenty-eight cases of monocytoid B-cell lymphoma of lymph nodes and 16 lymph node metastases of primary gastric lymphomas, mostly low-grade B-cell lymphomas of mucosa-associated lymphoid tissue (MALT) type were investigated morphologically and immunohistochemically. Both groups showed the same morphological and immunohistochemical features: diagnostically important sites of infiltration were th...

BACKGROUND Serum CA125 (sCA125) was recently reported to be of clinical value in the staging and follow-up of patients with non-Hodgkin's lymphoma (NHL). This report aims to investigate the prognostic value of a new serologic index combining sCA125 and LDH serum levels. PATIENTS AND METHODS One hundred thirty-seven patients were studied, sixty-three with histologically proven low-grade NHL, a...

balo's concentric multiple scleroses (ms) is a rare demyelinating disease and a variant of multiple sclerosis. we report a case with interesting misleading clinical history and typical ri findings of balo disease. a 19-year-old girl presented with fever and left hemiparesis following dental procedure 15 days ago. on physical examination fever and left limbs forces loss were noted. on ct scan a ...
