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.

MALT Lymphoma (Extranodal Marginal Zone B-Cell Lymphoma)

2013
Extranodal marginal zone lymphoma (MALT lymphoma) comprises approximately 8 % of non-Hodgkin’s lymphomas. Recurrent karyotype abnormalities, despite involving different genes, appear to affect the same signalling pathway, resulting in the activation of nuclear factor-kappa B (NF-κB).

Marginal Zone B-Cell Orbital Lymphoma With Intracranial Involvement

Ophthalmic Plastic & Reconstructive Surgery, 2010
A 40-year-old woman presented to the eye clinic with painless swelling of her right lower eyelid of 2 years' duration. Examination revealed severe loss of vision in the right eye with hypoglobus and exotropia. CT showed a diffuse right orbital infiltrative lesion with extension to the brain parenchyma.

Marginal zone B‐cell lymphoma: A retrospective immunophenotypic analysis

Cytometry Part B: Clinical Cytometry, 2008
AbstractBackground:Marginal zone B‐cell lymphoma (MZL) comprises three related yet biologically distinct subtypes—splenic MZL (SMZL), nodal MZL (NMZL), and extranodal MZL of MALT type (MALT). In cases without adequate morphology, immunophenotypic characterization by flow cytometric immunophenotyping (FCI) relies heavily on exclusion of other low‐grade ...

Splenic marginal zone B cell lymphoma

1999
The entity of splenic marginal zone lymphoma was listed originally in the REAL classification as a provisional entity but it is rapidly gaining full membership of the club. The histologic features which define it are listed [7.1].

Marginal Zone B-Cell Lymphomas Including Mucosa-Associated Lymphoid Tissue Type Lymphoma (MALT), Monocytoid B-Cell Lymphoma and Splenic Marginal Zone Cell Lymphoma and Their Relation to the Reactive Marginal Zone

Leukemia & Lymphoma, 1997
The marginal zone of the B follicle represents a well-defined compartment of the B area. Its cellular composition is distinct from that of the follicle centre, from which it also differs in its functional role in the immune response. Several newly identified lymphoma entities, e.g.
