Genetic abnormalities in marginal zone B‐cell lymphoma

Hematological Oncology, 2000
Marginal zone B-cell lymphoma (MZBCL) including extranodal mucosa-associated lymphoid tissue (MALT)-type lymphoma, nodal, and splenic MZBCL represents a distinct subtype of B-non-Hodgkin's lymphoma. Recently, important progress in the elucidation of the genetic mechanisms underlying the pathogenesis and disease progression of these lymphomas has been ...

Intracranial Marginal Zone B-Cell Lymphoma Mimicking Meningioma

World Neurosurgery, 2016
Marginal zone B-cell lymphoma of the meninges is a rare pathologic subtype of central nervous system lymphoma that can mimic the radiologic appearance of meningioma.We present a unique case of a 57-year-old man who presented with neurologic symptoms of severe headache, memory loss, mental status changes, and depression.

Marginal Zone B-Cell Lymphoma

2010
Marginal zone lymphoma (MZL) of extranodal mucosa-associated lymphoid tissue (MALT lymphoma), nodal MZL, and splenic B-cell MZL share similar morphologic and immunophenotypic features. All are proliferations of small B lymphoid cells that colonize the marginal zone of reactive germinal centers (GC).

Bilateral conjunctival extranodal marginal zone B‐cell lymphoma

Pediatric Blood & Cancer, 2010
AbstractExtranodal marginal zone B‐cell lymphomas (EMZLs), while relatively common in adults, are rare entities in the pediatric population. A subclass of the typically aggressive non‐Hodgkin lymphomas, the few reported pediatric cases indicate that, as in adults, these tumors tend to be indolent.

Nodal and splenic marginal zone B cell lymphomas

Hematological Oncology, 2005
AbstractSplenic marginal zone lymphoma (SMZL) and nodal marginal zone lymphoma (NMZL) are newly defined, separate clinicopathological entities. Both are rare lymphoma types, with low reproducibility in the diagnosis, although a conjunction of molecular and clinical studies seems to be now facilitating a more accurate diagnosis and understanding of the ...

Marginal zone B-cell lymphomas.

Discovery medicine, 2010
The term marginal-zone lymphoma (MZL) encompasses three closely related indolent B-cell non-Hodgkin's lymphoma subtypes, namely extranodal MZL or MALT lymphoma, nodal MZL, and splenic MZL. Although these neoplasms may share a common cell of origin, being the marginal zone B-cell, they display different characteristics with evident clinical and ...

Splenic Marginal Zone Lymphoma

The American Journal of Surgical Pathology, 1996
The splenic marginal zone is a morphologically and perhaps immunologically distinct B-cell compartment. Lymphomas arising from cells of the splenic marginal zone are rare. Here we describe the morphologic, immunologic, and clinical features of 14 cases. Patient age ranged from 35 to 79 years (median, 68 years) with a male-to-female ratio of 1:1.8.

Marginal Zone B-Cell Lymphoma (Maltoma)

2009
A low-grade lymphoma, maltoma, represents a form of marginal zone lymphoma arising from mucosal (bronchial) associated lymphoid tissue. Maltomas may arise de novo or be preceded by autoimmune disorders of the lung. Radiographically, maltoma may present as single or multiple nodular masses involving one or both lungs. Airways are usually not affected by

[Splenic marginal zone B cell lymphomas].

Der Pathologe, 2009
Splenic marginal zone B cell lymphomas (SMZBCL) are rare, organotypic, lymphoid neoplasms with distinct clinicopathological features. At initial presentation, the spleen, bone marrow and peripheral blood are usually involved, while generalized lymphadenopathy is only rarely observed.

Primary Marginal Zone B-Cell Lymphoma of the Larynx

Journal of Craniofacial Surgery, 2012
Extranodal non-Hodgkin lymphomas limited to the larynx are rare, accounting for less than 1% of all laryngeal neoplasms. The most common site of development of primary laryngeal lymphomas is the supraglottic region. In most cases, the presenting symptoms are hoarseness, dysphagia, dyspnea, and cervical lymphadenopathy.
