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...

Uterine lymphoma is a rare disease therefore, information regarding histologic type, immunophenotype of tumor cells and etiologic factors are limited. although secondary involvement of the genital tract occurs in up to 40% of cases• of disseminated lymphoma, lymphoma presenting with primary female genital tract . symptomatology is very unusual. We report a case of B-cell lymphoma in the ut...

  Primary non-Hodgkin lymphoma of liver is a very rare malignancy. Here we report a case of primary hepatic Burkitt’s lymphoma in a 34-year old man who was known case of acquired immunodeficiency syndrome (AIDS) and presented with weight loss, abdominal pain, and fever. Positive laboratory findings were mild anemia and elevated levels of lactate dehydrogenase (LDH) and alkaline phosphatase (AL...

primary cutaneous anaplastic large cell lymphoma is a t-cell malignancy with atypical cd30 positive lymphocytes. pseudoepitheliomatous hyperplasia is an uncommon finding in primary cutaneous anaplastic large cell lymphoma, and may mimic squamous cell carcinoma as pseudomalignancy. careful attention of a pathologist to correct diagnosis of pseudoepitheliomatous hyperplasia and its underlying cau...

Non-Hodgkin lymphoma is very uncommon in infancy and skin as the primary site of involvement in Non-Hodgkin lymphoma is rarely encountered. We describe a 10-month-old infant with T-cell Non-Hodgkin lymphoma who presented with multiple skin nodules as the predominant feature of her disease. The clinical manifestations, treatment strategy and disease outcome are reviewed. Key words: Non-Hodgk...

Background: Non-Hodgkin’s lymphoma (NHLs) is known as a heterogeneous group of malignant lymphoproliferative disorders. NHLs are classified into B cell and T cell types. Immunophenotypical assessment of the biopsy specimens can help diagnose NHLs.    Methods: In this study, 77 patients with B cell and T cell lymphoma were selected from Shahid Sadoghi hospital during 2010 to 2...

Primary gastrointestinal T-cell lymphoma is an uncommon entity and primary colon T-cell lymphoma is even rarer. The majority of enteropathy-associated T-cell lymphomas present predominantly as ulcers or strictures in the endoscopic examinations, while primary B-cell lymphomas commonly present as exophytic lesions. Ulcerative colon T-cell lymphoma may mimic Crohn's disease (CD), which is a chron...

BACKGROUND Non-Hodgkin lymphoma (NHL) is a well-known hematologic malignancy. The gastrointestinal (GI) tract is the most commonly involved extra nodal site. MALT lymphomas are uncommon, accounting for 5% of all NHL. Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is the prototype seen in association with Helicobacter pylori. Colonic MALT lymphoma is rare and comprises only 2.5% of th...
