A 61-year-old woman was admitted to our hospital with an ulcerated palate mass and swelling of the right parotid gland. Incisional biopsy from the hard palate revealed an extranodal marginal zone B-cell lymphoma, also called mucosa-associated lymphoid tissue (MALT) lymphoma. Final diagnosis was MALT lymphoma of the parotid gland with concomitant involvement of an extremely seldom site of involvement: the hard palate. To our knowledge, this report illustrates the first case of MALT lymphoma of the hard palate and parotid gland without an underlying autoimmune disease...

PURPOSE: To assess the clinical outcomes of radiotherapy (RT) using two-dimensional (2D) and three-dimensional conformal RT (3D-CRT) for patients with gastric mucosa-associated lymphoid tissue (MALT) lymphoma to evaluate the effectiveness of involved field RT with moderate-dose and to evaluate the benefit of 3D-CRT comparing with 2D-RT. MATERIALS AND METHODS: Between July 2003 and March 2015, 33 patients with stage IE and IIE gastric MALT lymphoma received RT were analyzed...

Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is a rare extranodal marginal zone B-cell lymphoma that is often associated with plasmacytic differentiation. However, the clinicopathologic characteristics of gastric MALT lymphoma with increased plasmacytic differentiation have not yet been studied. To assess the clinicopathologic implications of gastric MALT lymphoma with increased plasmacytic differentiation, thirty-six cases with increased plasmacytic differentiation and a control group of 16 cases with minimal plasmacytic differentiation were retrospectively collected from 65 primary gastric MALT lymphomas (2010~2012)...

Marginal zone lymphoma (MZL) is a low-grade B-cell lymphoma derived from marginal-zone B cells. Because of a lack of specific immunohistochemical markers, MZL is mainly diagnosed based on the cytological appearance and growth pattern of the tumor. Marginal-zone B cells were recently shown to selectively express immunoglobulin superfamily receptor translocation-associated 1 (IRTA1), but the antibody used in that study is not commercially available. We therefore investigated the IRTA1 expression in non-neoplastic lymphoid tissues and 261 malignant lymphomas, examining the ability of a commercially available antibody to accurately diagnose MZL...

PURPOSE: To determine whether interim F-FDG PET or interim diffusion-weighted magnetic resonance imaging (DWI) can predict the end-of-treatment (EOT) outcome after immunotherapy in patients with FDG-avid extranodal marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT). MATERIALS AND METHODS: Patients with untreated MALT lymphoma prospectively underwent whole-body F-FDG PET/CT and DWI before treatment (baseline), and after three cycles (interim) of rituximab-based immunotherapy...

PURPOSE: The aim of this study was to determine rates of positive findings on positron emission tomography (PET) and bone marrow biopsy performed during staging workup for ocular adnexal lymphoma (OAL). METHODS: A retrospective review of OAL patients was conducted. Demographics, primary versus secondary OAL, histologic subtype, and findings on PET and bone marrow biopsy performed as part of the initial staging workup for OAL were recorded. RESULTS: The study included 119 patients with OAL...

Benign lymphoepithelial lesions (BLLs) usually affect the parotid glands, resulting in their asymmetrical enlargement. The condition can be associated with Sjögren's syndrome (SS), which in turn may predispose the affected patient to the development of malignant lymphoma. BLLs arising in the intraoral minor salivary glands are rare; such a lesion should prompt the work-up for SS. In some instances, a BLL of a minor salivary gland could represent the initial stage of a mucosa-associated lymphoid tissue (MALT) lymphoma...

Persistent bacterial infections of the gastrointestinal mucosa are causally linked to gastric carcinoma and mucosa-associated lymphoid tissue (MALT) lymphoma in people and laboratory animals. We examined the relationship of mucosa-associated bacteria to alimentary lymphoma in cats. Intestinal biopsies from 50 cats with alimentary lymphoma (small cell, n = 33; large cell, n = 17) and 38 controls without lymphoma (normal to minimal change on histopathology, n = 18; lymphocytic-plasmacytic enteritis, n = 20) were evaluated...

MALT: Mucosa-associated lymphoid tissue (MALT)-type lymphoma is a relatively rare disease; nevertheless, it is the third most common lymphoma type, accounting for 5-7% of all non-Hodgkin lymphomas. Case series and retrospective analysis published in the literature have suggested that extra gastrointestinal (GI) MALT-type lymphoma can occur simultaneously with MALT-type lymphoma involving the GI tract. We report the case of a healthy, 64-year-old Caucasian male who presented with progressive fatigue, non-productive cough, and worsening exertional shortness of breath for 3 months who was subsequently diagnosed with gastric extra-nodal marginal zone B-cell lymphoma or MALToma with simultaneous metastasis to the lung (bronchi) based on biopsy reports...

Mucosa-associated lymphoid tissue (MALT) lymphoma mainly consists of three types of tumor B cells, small (centrocyte-like), scattered large transformed, and intraepithelial. However, it is difficult to differentiate tumor B cells from reactive B cells at the cellular level. We examined five cases of API2-MALT1 fusion-positive MALT lymphoma of the lung. A single paraffin section for each case was subjected to sequential retrieval of whole-slide imaging (WSI) data of hematoxylin and eosin (HE) staining, immunofluorescence staining for CD79a, and fluorescence in situ hybridization (FISH) for the MALT1 split...

Crystal-storing histiocytosis (CSH) is characterized by the accumulation of large histiocytes with intracytoplasmic crystallized immunoglobulin and is typically associated with hematological malignancies. A 69-year-old man, who had a history of left nephrectomy and chemotherapy for renal pelvic cancer six years earlier, had received a CT scan every year thereafter and a small nodule was found in the left lower lobe of his lungs two years prior to the current presentation. Because of progression of this pulmonary nodule, he underwent pulmonary lobectomy on suspicion of lung cancer...

Tissue eosinophilia is rarely observed in cases of non-Hodgkin's lymphoma of B cell origin. The present study describes a rare case of mucosa-associated lymphoid tissue (MALT) lymphoma, which was initially misdiagnosed as eosinophilic pneumonia. The initial diagnosis was formed based on the results of chest radiography, peripheral eosinophilia tests and bronchoalveolar lavage, and the clinical course of the patient. Following administration of methylprednisolone (40 mg/day) for 4 days and oral administration of prednisolone (30 mg/day), the clinical course rapidly improved and the eosinophil count immediately decreased a to normal level...

Papillary thyroid cancer (PTC) represents 80-85% of thyroid cancer and its prevalence has been rising in the last decades. Primary thyroid lymphoma (PTL) accounts for 3% of extranodal lymphomas and about 5% of thyroid malignancies, having a prevalence of one or two cases per million people. Mucosa-Associated Lymphoid Tissue lymphoma represents approximately 30% of PTL. Both entities have an indolent course and a very good prognosis. Diagnosis is made by ultrasound and fine needle aspiration (FNA) or surgery specimen pathology...

Primary biliary mucosa-associated lymphoid tissue (MALT) lymphoma is extremely rare. We report a case of primary biliary MALT lymphoma with obstructive jaundice diagnosed by endoscopic biopsy, without surgical intervention. Obstructive jaundice was relieved by endoscopic drainage and endoscopic biopsy was done simultaneously during endoscopic retrograde cholangiopancreatography. Unnecessary surgical intervention can be avoided after pathological confirmation of lymphoma. The patient received radiotherapy, and is alive without any evidence of recurrence or biliary obstruction...
