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...

One of the rare variants of extranodal large B-cell lymphoma is intravascular large B-cell lymphoma (IVLBCL). Characteristics of IVLBCL include intraluminal selective proliferation of atypical lymphoid cells in small to medium-sized vessels. The etiologic of IVLBCL is unknown, but due to the growth pattern of this tumor, it is speculated that IVLBCL is caused by a defect in homing receptor of t...

Primary testicular lymphoma (PTL) is a rare form of extranodal lymphoma, this neoplasm the most common malignant tumor testis in elderly age, and majority cases are histologically diffuse large B-cell (DLBCL), accounting for 80% to 98% non-hodgkin lymphoma. Patients with primary DLBCL show continuously high risk recurrence no plateau survival curves tendency involve other sites, especially cent...

Classification and proper treatment of extranodal lymphoma is hindered by the diversity of lymphoma types and the relative rarity of many of these tumour types. In order to review controversial issues in extranodal lymphoma diagnosis, a joint Workshop of the European Haematopathology Association (EAHP) and the Society for Hematopathology (SH) was held, where 99 selected cases were reviewed and ...

Introduction: Diffuse large B-cell lymphoma is the largest subtype of non-Hodgkin’s lymphomas, and is characterized by frequent extranodal presentation. The most common extranodal locations of non-Hodgkin’s lymphomas are: stomach, bone, liver and testis. Simultaneous detection of multiple extranodal involvements during consultation is quite uncommon, and the majority of cases are characterized ...

Mantle cell lymphoma is an aggressive type of B-cell non-Hodgkin's lymphoma that originates from small to medium sized lymphocytes located in the mantle zone of the lymph node. The gastrointestinal tract is the predominant site of extranodal involvement in the form of multiple lymphomatous polyposis. Multiple lymphomatous polyposis due to mantle cell lymphoma presenting with intussusception is ...
