Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is the third most common non-Hodgkin lymphoma subtype, accounting for around 6-8% of all non-Hodgkin lymphomas in the Western hemisphere. Although MALT lymphomas are clinically indolent, the disease is typically chronic, requiring long-term clinical surveillance and, often, repeated biopsies. Pathologists thu...

Mucosa-associated lymphoid tissue (MALT) lymphoma is a form of low-grade malignant B-cell extranodal non-Hodgkin's lymphoma. It is classified as marginal-zone lymphoma and represents less than 1% of all lung cancer. We describe a case of MALT lymphoma limited exclusively to the lung that came to our attention with infective pleural effusion and concomitant lung consolidation of the left lower l...

Barley grain carries a numerous, variable, and complex microbial population that mainly consists of bacteria, yeasts, and filamentous fungi and that can partly be detected and quantified using plating methods and microscopic and molecular techniques. The extent and the activity of this microflora are determined by the altering state of the grain and the environmental conditions in the malt prod...

Primary hepatic extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) type lymphoma is very rare disease. We reported two cases of primary hepatic MALT lymphoma associated with chronic inflammatory disorder. One case was a 74-year-old female complicated with asymptomatic primary biliary cirrhosis. Another case was a 73-year-old man presented with a mild hepatitis C. Both...

Papillary thyroid carcinoma (PTC) is a common affliction of the thyroid gland, accounting for 70% to 80% of all thyroid cancers, whereas mucosa-associated lymphoid tissue (MALT) lymphoma of the thyroid gland is uncommon. The simultaneous occurrence of both malignancies is extremely rare. We report the case of a patient with both PTC and MALT lymphoma in the setting of Hashimoto thyroiditis. An ...

A 66-year-old female presented with a 1-month history of dyspepsia. An initial upper gastrointestinal endoscopy with biopsy revealed a low-grade mucosa-associated lymphoid tissue (MALT) lymphoma. A rapid urease test was positive for Helicobacter pylori. Endoscopic ultrasound (EUS) and computed tomography (CT) revealed a 30×15-mm lymph node (LN) in the subcarinal area. Histopathologic and phenot...

A 52-year-old woman with tracheal lesions underwent tracheal resection and carina reconstruction directly because histopathologic diagnosis was not obtained before surgery. Postoperative pathological analysis confirmed a diagnosis of mucosa-associated lymphoid tissue (MALT) lymphoma. Subsequently, she suffered serious complications of tracheal stenosis, bronchial stenosis, and tracheoesophageal...

The concept of mucosa-associated lymphoid tissue (MALT) lymphomas was introduced by Isaacson and Wright [Cancer 1983; 52:1410-1416] in 1983. After more than 20 years of clinical research MALT lymphomas are now recognized as a distinct subtype of non-Hodgkin's lymphoma (NHL) with unique pathogenic, histological, and clinical features. Although this subtype of NHL occurs frequently, optimal manag...

Primary renal lymphomas are very rare since renal involvement by the disease is most often a manifestation of disseminated disease. We report an 88-year-old man with low-grade extranodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (MALT) (MALT lymphoma) arising in the kidney. After the workup, the patient was thought to have renal cell carcinoma and underwent partial neph...

The indolent and favorable clinical course of extranodal B cell lymphoma of mucosa-associated lymphoid tissue type (MALT lymphoma) of stomach is well known. For both physician and patient, one of the most fearful parts for gastric MALT lymphoma must be the bone marrow aspiration and biopsy (BMAB) rather than the disease itself. Guidelines from authorities still does not reach to a concurrence o...
