OBJECTIVES Hepatitis C virus infection has a 10.5% frequency in liver transplant posttransplant lymphoproliferative disorders. Studies have suggested that hepatitis C virus infection plays a role in developing posttransplant lymphoproliferative disorders. Pooling data of posttransplant lymphoproliferative disorders developing in liver recipients from the literature, we analyzed and compared cha...

autoimmune lymphoproliferative syndrome (alps) is a prototypic disorder of abnormal lymphocyte homeostasis. in the september 2005 issue of the iranian journal of allergy, asthma and immunology, a patient with clinical features consistent with alps was described. although the clinical presentation was in favor of alps, a precise diagnosis needed more laboratory evaluations.

The association of mycosis fungoides and a primary cutaneous CD30+ lymphoproliferative disorder has been reported and probably represents different clinical aspects of a unique T-cell monoclonal expansion. In this study, 12 patients (6 men and 6 women) presented with lymphomatoid papulosis and mycosis fungoides. A TCRgamma gene rearrangement study was performed by an automated high-resolution P...

A case of a 16-year-old female with polyarticular juvenile idiopathic arthritis (JIA) since the age of 4 years is reported here. This patient also suffered from multiple congenital anomalies. On long-term treatment with oral methotrexate (MTX) and etanercept, multiple subcutaneous nodules were detected, which were accompanied by increased lactate dehydrogenase and uric acid levels.

Introduction: Epstein-Barr virus (EBV)-positive mucocutaneous ulcer is an unusual form of lymphoproliferative disorder and usually arises in immunocompromised patients, including those with advanced age-associated immunosenescence, iatrogenic immunosuppression, primary or infection-associated immune disorder. Pseudomonas aeruginosa has become a real concern hospital-acquired infections, especia...

The histopathologic diagnosis of orbital and ocular adnexal lymphoproliferative lesions is difficult, resulting contraversy in classification, determining benignity or malignancy of them and treatment modality selection. We designed the following study to evaluate clinical, histopathologic and if necessary immunochemical features of them in decreasing indeterminate cases. The study includes 51 ...

INTRODUCTION Mucosa associated lymphoid tissue lymphomas are the most common lymphomas of the salivary glands. The benign lymphoepithelial lesion is also a lymphoproliferative disease that develops in the parotid gland. In the present case report, we describe one case of benign lymphoepithelial lesion with a subsequent low transformation to grade mucosa associated lymphoid tissue lymphoma appea...
