Background: Coexistence of splenic marginal zone lymphoma with hepatocellular carcinoma is rare. Although some reports have suggested the possible pathogenic role of HBV, HCV, chronic and persistent antigenic stimulation in lymphoma, their role in causing lymphomas is still unclear. Case presentation: We describe a hepatocellular carcinoma with concomitant splenic marginal zone lymphoma in a 64...

Regulatory T cells (Tregs) play a central role in protecting the host from autoimmune diseases. However, Tregs also pose a major problem to anti-tumor immunity. The expansion and accumulation of these immunosuppressive cells correlate with advanced tumor growth and predict poor disease prognosis. The study aims at evaluation of the clinical role of regulatory T cells in B-cell Non-Hodgkin's lym...

Primary cutaneous marginal zone lymphoma (MZL) is a common B-cell lymphoma of skin and is characterized by an infiltrate of neoplastic marginal zone B cells typically within the marginal zones of reactive lymphoid follicles and the interfollicular region. However, in our experience, many cases have underemphasized features such as marked plasmacytic differentiation and/or a prominent T-cell com...

In this issue of the Journal, Baseggio et al. 1 report on a series of 24 patients with CD5-positive, t(11;14)-negative splenic marginal zone lymphoma (SMZL) diagnosed by means of cytology and flow cytometry of peripheral blood. All the patients were splenectomized at diagnosis or during follow-up and, consequently, spleen specimens were available for histological examination in all cases. The b...

Splenic marginal zone lymphoma (SMZL) is a low-grade B-cell non-Hodgkin's lymphoma characterized by massive splenomegaly, moderate lymphocytosis with or without villous lymphocytes, rare involvement of peripheral lymph nodes and indolent clinical course. As a rare disease, with no randomized prospective trials, there is no standard of care for SMZL so far. Splenectomy has been done for many yea...

Monoclonal gammopathy occurs in one-third of the patients with mucosa-associated lymphoid tissue lymphoma (MALT lymphoma). However, monoclonal gammopathy has been rarely reported in Korea. Paraprotenemia accompanying MALT lymphoma is strongly correlated with involvement of the bone marrow, and this involvement leads to the progression of the disease. Here, we present a case of a 66-yr-old man d...

Primary dural lymphoma is a rare disease with more indolent clinical behavior compared to primary central nervous system lymphoma. The majority of the reported cases were indolent marginal zone lymphoma subtype with more predilections to the spine. Herein, we are presenting a case of intracranial, diffuse large B-cell lymphoma of the dura that was diagnosed and treated at our institution. We ar...

The association between hepatitis C virus (HCV) infection and B-cell non-Hodgkin's lymphomas (NHL) has been demonstrated by epidemiological studies, in particular in highly endemic geographical areas such as Italy, Japan, and southern parts of United States. In these countries, together with diffuse large B-cell lymphomas, marginal zone lymphomas are the histotypes most frequently associated wi...

Study Design Case report. Objective Most spinal lymphomas occur in the context of systematic lymphomas. Marginal zone lymphoma (MZL) is a type of B-cell lymphoma originating from the marginal zone of B-cell follicles. Mucosa-associated lymphoid tissue (MALT) lymphoma is a type of extranodal MZL and rarely occurs in the central nervous system. To date, there has been only one case report of prim...

BACKGROUND Mucosa-associated lymphoid tissue (MALT) lymphoma is among the most common forms of extranodal lymphomas, but little is known about subcutaneous involvement in patients with non-primary cutaneous marginal zone lymphomas. DESIGN AND METHODS Patients with MALT lymphoma diagnosed and treated at our institution between 1999 and 2010 were analyzed for subcutaneous deposits from MALT lym...
