INTRODUCTION Marginal zone B-cell lymphoma is a rare disease which can be considerably difficult to recognize and diagnose when signs of systemic involvement are absent. CASE PRESENTATION We report the case of a 57-year-old woman with initial olfactory disturbance, followed by psychosis, diabetes insipidus and hypothalamic eating disorder as an uncommon clinical presentation of marginal zone ...

The article by Thieblemont and colleagues very nicely summarizes the key pathogenetic and diagnostic features and present treatment of splenic marginal zone lymphoma (SMZL). This histologic subtype of non-Hodgkin lymphoma has evolved from being an unrecognized entity in earlier classification systems (such as the Working Formulation[1]), to a provisional entity in the Revised European/American ...

Marginal zone lymphomas of all types (nodal, splenic, and extranodal mucosa-associated lymphoid tissue [MALT]) may show plasmacytic differentiation. Distinguishing marginal zone lymphomas from other small B-cell lymphomas with plasmacytic differentiation, especially lymphoplasmacytic lymphoma, or from plasma cell neoplasms may be challenging. Marginal zone lymphomas with plasmacytic differentia...

We present seven cases of mantle cell lymphoma with morphological features of marginal-zone lymphoma. Of particular interest, four of the patients had predominant involvement of the gastrointestinal tract. All cases displayed the translocation t(11;14)(q13;q32) and expressed cyclin D1. Cytogenetic analysis revealed trisomy 3 in one case and somatic hypermutation of immunoglobulin heavy genes co...

BACKGROUND The marginal zone is an anatomically distinct B-cell compartment of lymphoid tissue with an abundant antigenic influx. Among marginal zone-derived lymphomas the WHO classification listed, in addition to extranodal marginal zone B-cell lymphoma of MALT type, two other marginal zone B-cell neoplasms: splenic marginal zone B-cell lymphoma (+/- villous lymphocytes) and nodal marginal zon...

Splenic diffuse red pulp lymphoma is an indolent small B-cell lymphoma recognized as a provisional entity in the World Health Organization 2008 classification. Its precise relationship to other related splenic B-cell lymphomas with frequent leukemic involvement or other lymphoproliferative disorders remains undetermined. We performed whole-exome sequencing to explore the genetic landscape of te...

we report a case of membranoproliferative glomerulonephritis (mpgn) with igmκ light chain deposits in a patient with chronic hepatitis c infection and simultaneous onset of monoclonal igmκ gammopathy with concurrent small b-cell lymphoproliferative disease. the patient presented with hepatosplenomegaly and a uremic state that necessitated dialysis without any clinical signs of systemic disease ...

Primary low-grade B-cell lymphomas of the thymus are rare, with only 7 reported cases in the literature. We describe 3 cases of primary low-grade thymic lymphoma. All had histologic features of extranodal marginal zone lymphoma and were composed predominantly of small lymphocytes with variable components of monocytoid cells and plasma cells. Overt transformation to large cell lymphoma occurred ...

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is an extranodal lymphoma composed of morphologically heterogeneous small B-cells including marginal zone (centrocyte-like) cells, cells resembling monocytoid cells, small lymphocytes, and scattered immunoblasts and centroblast-like cells. There is plasma cell differentiation in a proportion of the cases. The...

PURPOSE To evaluate the efficacy of radiotherapy (RT) for early-stage nodal and extranodal marginal zone lymphoma (MZL). MATERIALS AND METHODS Patients with stage I (n = 22) and stage II (n = 8) MZL, who were treated with RT were reviewed. The primary tumor localisation was in the orbita (n = 12), stomach (n = 8), head and neck other than the orbita (n = 8), breast (n = 1) and one case of mar...
