PURPOSE Primary thyroid lymphoma (PTL) is a rare disease and it has been investigated in a limited number of studies. The present multicenter study evaluated the clinical features and treatment outcomes of PTL. METHODS The medical records of patients diagnosed with PTL between 2000 and 2013 in three centers were retrospectively reviewed. RESULTS The study included 11 men and 27 women with a...

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...

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...

piration cytology (FNAC) has increased to around 5060% (1), chronic lymphocytic thyroiditis and small cell undifferentiated carcinoma (anaplastic carcinoma) are still being confused with thyroid lymphoma (2). No reports concerning the ultrasonographic (US) and computed tomographic (CT) features of primary mucosa-associated lymphoid tissue (MALT) lymphoma have yet been published in the Korean ra...

Primary thyroid lymphoma is a rare malignancy, representing 2-8% of all thyroid malignancies and 1-2% of all extranodal lymphomas. The majority of cases concern non-Hodgkin's lymphoma of B cell origin, following by Hodgkin's disease, T cell lymphomas and rarely marginal zone B-cell mucosa-associated lymphoid tissue (MALT) lymphomas. MALT lymphomas have been associated with long-standing autoimm...

Thyroid lymphoproliferative disorder is known to be associated with Hashimoto thyroiditis. The major histological types of thyroid disorders are malignant lymphoma, such as diffuse large B cell extranodal marginal zone lymphoma mucosa-associated lymphoid tissue (MALT), and follicular lymphoma. All these lymphomas; however, T represent only a minority cases. Since rarely develops heterogeneous e...

Mucosa-associated lymphoid tissue (MALT) lymphoma is a common type of lymphoma in extranodal sites. The most frequent chromosome translocation associated with MALT lymphoma is t(11;18)(q21;q21), which generates a chimeric protein of c-IAP2 and MALT1/paracaspase. The c-IAP2/MALT1 fusion protein activates the NF-kappaB pathway, which is considered critical to malignant B cell transformation and l...

Neoplasm from the accessory parotid glands (APG) rarely occurs, and its malignancy rate is higher than other salivary glands. The B-cell lymphoma APG rare, with less 2% of all in APG. mucosa-associated lymphoid tissue (MALT) lymphoma, a subtype tends to be localized disease an indolent clinical course. It very rare for MALT develop bilaterally without autoimmune disease. A 43-year-old male pres...

A 60-year-old man was admitted to our hospital with sudden onset of motor aphasia, Gerstmann syndrome, and incomplete right hemiparesis one week after administration of chemotherapy for mucosa-associated lymphoid tissue (MALT) lymphoma. Computed tomography showed an intracerebral hematoma in the left subcortical area. Cerebral angiography revealed 2 aneurysms on the distal middle cerebral arter...

BACKGROUND Possibly any tumor that can cause mechanical obstruction of the distal bile duct can induce acute pancreatitis. However, acute pancreatitis as the first clinical manifestation of duodenal lymphoma is extremely rare. OBJECTIVE To report the case of a patient with acute pancreatitis as an extremely rare first manifestation of duodenal MALT lymphoma and possible association with eryth...
