The group of marginal zone B-cell lymphomas (MZL) comprises three different entities, extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (currently called MALT lymphoma), nodal marginal zone B-cell lymphoma (previously known as monocytoid lymphoma), and splenic marginal zone B-cell lymphoma (with or without circulating villous lymphocytes).[1-3] Primary splenic and no...

The present study described for the first time a high heterogeneity of blood vessels in non-Hodgkin lymphomas (nHL). The tumor blood vessels were highlighted with CD105÷smooth muscle actin (SMA) and CD34/SMA double immunostaining. For both follicular and diffuse types of lymphomas, more than 85% of CD34/SMA positive vessels were of immature and intermediate type. A percent of 96.54 from CD105/S...

Introduction Primary bone lymphoma (PBL) is a rare disease that was first described by Oberling in 1928.1 The vast majority of PBL cases are non-Hodgkin lymphoma (NHL), whereas primary Hodgkin lymphoma (HL) of bone is extremely rare. PBL constitutes 7% of all malignant bone tumors, 4-5% of all extranodal NHL, and less than 1% of all malignant lymphomas.2-5 Patients with primary NHL of bone comm...

INTRODUCTION Anthracyclines have been widely used in the treatment of haematological malignancies. Their major adverse effect is cardiomyopathy, but their effect on vascular elasticity has not been completely elucidated. The aim of the present study was to investigate the effects of anthracyclines on aortic elastic properties in patients with lymphomas. METHODS We studied 70 patients with lym...

UNLABELLED Lymphomas account for less than 5% of thyroid malignant lesions. Vast majority of them are B-cell non-Hodgkin lymphomas (NHL), while Hodgkin lymphoma (HL) is extremely rare. Here we present two cases of HL, at baseline manifesting as a thyroid lesion. First patient, 29-year-old pregnant female, initially suspected for metastatic medullary thyroid cancer, was eventually diagnosed with...

Introduction: The number of patients living after a cancer diagnosis is increasing, especially hemolymphopoietic and thyroid (TC). This study aims at evaluating both the risk second in TC as cancer. Methods: Two population-based cohorts aged up to 84 years were identified from 28 Italian registries 1998–2012. first included cancers with cancers. Standardized incidence ratios (SIR) SPC stratifie...

Lymphoma which has a wide range of manifestations is the third malignancy in pediatrics. Nearly, 50% of patients have extranodal involvement. Pancreas can be affected secondarily more than primarily. A 10-year-old boy with recurrent abdominal pain in the epigastric region for six weeks was referred to Amirkola Childrenchr('39')s Hospital, affiliated to Babol University of medical sciences (nort...
