AIMS To evaluate the chromosomal translocation t(11;18)(q21;q21) in gastrointestinal lymphomas. METHODS A possible API2-MLT fusion transcript specific to t(11;18)(q21;q21) was examined by means of reverse transcription-polymerase chain reaction (RT-PCR) in tumours from 47 cases of primary gastrointestinal lymphoma (28 low grade mucosa associated lymphoid tissue (MALT) lymphomas, four low grad...

Originally reported to be associated with a low-grade mature B-cell phenotype with plasmacytoid differentiation such as lymphoplasmacytic lymphoma, multiple myeloma/ plasma cell leukemia and chronic lymphocytic leukemia. However, the relatively frequent occurrence in diffuse large B-cell lymphoma, with or without a preceding faze of a low-grade lymphoma, suggests that this chromosomal aberratio...

Mucosa-associated lymphoid tissue lymphoma (MALToma) is a low grade B-cell lymphoma that develops from the lungs, intestinal tract, salivary gland, and other organs and is included under extranodal marginal zone lymphoma. When a primary pulmonary MALToma develops from bronchus-associated lymphoid tissue (BALT), it is called BALT lymphoma (BALToma). The etiology of MALToma is not clear; however,...

Eighty one cases of non-Hodgkin's lymphoma were examined by DNA flow cytometry, using fixed embedded histological tissue. The frequency of detection of DNA aneuploidy and the values for S phase fractions depended on the histological subtype and grade of lymphoma. Twenty two of the patients with low grade centroblastic/centrocytic non-Hodgkin's lymphoma had repeat biopsies. Eleven of these patie...

Characteristic chromosomal aberrations have been associated with subtypes of non-Hodgkin's lymphoma with distinct clinicopathologic features. Low-grade B-cell lymphomas of mucosa-associated lymphoid tissue (MALT) form such a group and might be expected to be characterized by a specific cytogenetic abnormality. Metaphase analyses of MALT lymphoma are rare due to problems with fresh tissue collec...

PATIENT Female, 91 FINAL DIAGNOSIS: Low-grade gastric MALT lymphoma Symptoms: Recurrent epigastric and right upper quadrant dyscomfort Medication: Rituximab Clinical Procedure: esophagogastroduodenoscopy • gastric biopsy Specialty: Gastroenterology. OBJECTIVE Unusual or unexpected effect of treatment. BACKGROUND Mucosa associated lymphoid tissue (MALT) lymphoma can occur in any extranodal o...

Humoral hypercalcemia of malignancy is a common metabolic disturbance associated with solid tumors, but it also occurs in lymphoma patients. Among these, low grade B-cell lymphoma accounts for only few cases, in which secretion of parathyroid hormone-related protein (PTHrP) remains even exceptional. We report the very rare case of a patient with a CLL type low grade leukemic B-cell lymphoma sho...

The larynx is an extremely rare site of involvement by lymphomatous disease. We present two cases of isolated laryngeal high-grade and another low-grade lymphoma, together with a literature review of laryngeal lymphoma management.

AIMS Primary lymphoma of the thyroid gland (PTL) is a relatively rare disease. During an 18-year period, 53 cases of primary non-Hodgkin's lymphoma involving this extranodal site were seen at our institutions. The aims of this study were to evaluate the spectrum of PTLs using current lymphoma classification concepts and immunocytochemical markers, determine whether features of MALT-type lymphom...
