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. In cases with head and neck lymphoma, other variables such as age, sex, specific lo...

The authors describe a case of histiocyte-rich B-cell lymphoma (HR-BCL), a variant of diffuse large B-cell lymphoma, in a 51-year-old man. The patient presented with large axillary lymphadenopathy. Histopathologic and immunohistochemical examination of lymph node biopsy revealed diffuse effacement of the lymph node architecture by reactive histiocytes and neoplastic CD20 positive B cells. ...

Subjects methods: A cross-sectional sampled 76 patients be examined treated at H...

Three cases of primary non-Hodgkin's lymphoma of the larynx are described. Histologically, two tumours belonged to the category of low grade B-cell lymphomas of the small cell type (extranodal marginal zone B-cell lymphoma and lymphoplasmacytoid lymphoma), and the third was classified as a peripheral T-cell lymphoma of unspecified type. The clinical stage was IE in two cases, and IV in another ...

In one study by Oyama et al., pleural effusions were noted in ni...

OBJECTIVES Recently described, aggressive B-cell lymphomas with genetic abnormalities involving MYC and BCL2 have been shown to have a poor prognosis when treated with regimens for diffuse large B-cell lymphomas. Similar data on cases with concurrent MYC and BCL6 translocation are still scant. Moreover, little is known regarding the morphologic and immunophenotypic characteristics of these case...
