non hodgkin lymphomas (nhl) are nodal or extra nodal monoclonal infiltrations by malignant lymphoid cells (b lymphocytes in 80% of cases), which are distinguished as indolent or aggressive forms. according to the heterogeneity of lymphoid cells and their ubiquitous anatomical distribution, these disorders can develop in any organ and have very heterogeneous clinical expressions, but they are us...

nonexposed colleagues, and that uncorrected number was statistically signifi cant. Elevated rates emerged for prostate and thyroid cancer, melanoma, non-Hodgkins lymphoma, multiple myeloma, and leukemia. With the prevalence of cancer in the general population, at least some of the increases were probably an artifact of the intensifi ed screenings that 9/11 fi rst responders in the study receive...

BACKGROUND Small B-cell non-Hodgkins lymphoma (NHL) is difficult to be distinguished from non-neoplastic reactive processes using conventional haematoxylin-eosin (HE) staining due to different interpretations among pathologists with diagnosis based on morphologic features. Ancillary examinations such as immunohistochemical (IHC) staining are essential. However, negative or doubtful results are ...

Introduction: This study is aimed to assess the prevalence and characteristics of head and neck lymphoma in a defined group of an Iranian population.   Materials and Methods: In this retrospective study, 126,450 biopsy reports from two referral Pathology Departments, (Tehran, the capital of Iran) were evaluated.
