Objective(s): The aim of this study is to evaluate the role of PET-CT in identification of different patterns of extranodal involvement in Hodgkin’s disease (HD) and Non-Hodgkin’s Lymphoma (NHL) and to enlist the common sites of extranodal involvement in each histological type and compare our results with the existing literature. Methods: In this retrospective study of 281 cases of lymphomas of...

156 Iranian patients with primary malignant tumors of the small intestine were reviewed. Malignant lymphoma was the most common tumor type, comprising 128 patients (82%), followed by adenocarcinoma (22 patients, 14.1 %), leiomyosarcoma (4 patients, 2.56%) and carcinoid tumor (2 patients, 1.28%). Lymphomas and adenocarcinomas were primarily located in the duodenum or jejunum, whereas leiomy...

  Background and Objectives: Classic Hodgkin lymphoma (CHL), anaplastic large cell lymphoma (ALCL) and some cases of diffuse large B cell lymphoma (DLBCL) have overlapping morphologic features. Since they all represent distinct clinico-pathologic entities, we explored the differential diagnostic impact of immunophenotyping to discriminate between them. Materials and Methods:...

background: post-transplant lymphoproliferative disorders (ptld) are a complication of chronic immunosuppressive therapy in solid organ transplantation with a high mortality rate. alternative treatments such as rapamycin have been explored. methods: a detailed retrospective analysis was performed according to data collected from 13 patients with ptld. at the time of ptld diagnosis, immunosuppre...

common radiologic features of lymphoma in lung are included: adenopathy, pleural effusion, multiple or solitary masses and diffuse infiltration. we want to present a 28y/o male with pulmonary hodgkin lymphoma with a rare radiographic pattern and distinct histologic description that at first misdiagnosed as pulmonary tuberculosis but eventually lung biopsy confirmed diagnosis of pulmonary hodgki...

primary malignant lymphoma of the male external genitalia is extremely rare and it is even rarer in the penis. because of its rarity, the possibility of delay in diagnosis and mismanagement is always there. it can present as a nodule, non-healing ulcer, stricture urethra or periurethral abscess. we report a case presenting first a nodule and later on as a non-healing ulcer which was diagnosed b...

although involvement of the heart by malignant lymphoma is relatively common, it is unusual to be detected premortem. we report a case of hodgkin's lymphoma who presented with systemic signs and symptoms including abdominal distension, weakness, pallor, chills and fever, hepatosplenomegaly and generalized lymphadenopathy as well as signs of heart failure. echocardiography revealed lucent myocar...

introduction: burkitt lymphoma (bl) is rare, but an aggressive malignancy. central nervous system burkitt lymphoma (cnsbl) is very rare. cns burkitt’s lymphoma is treated with high-dose chemotherapy and radiation. radiotherapy in children younger than three years old may cause major cns damage. case report: a three-year-old boy presented with painful proptosis of the left eye. he underwent aden...

background and objectives: hepatitis c virus (hcv) is a major public health problem worldwide. replication and persistence of hcv genome have been described in the liver tissue as well as b cells lymphocyte. several investigations have reported that long-term persistence of hcv in b cells may result in hodgkin and non-hodgkin lymphoma. this study was aimed to determine frequency of hcv rna in h...
