INTRODUCTION Breast involvement in Non Hodgkin Lymphoma is a rare entity as it accounts for 2.2% of all extranodal lymphomas. PRESENTATION OF CASE A 59-year-old woman was referred to our Breast Unit because of two nodules of the right breast newly discovered during her annual mammography. Moreover, during the physical examination, a red-brown itchy lump of the scalp was discovered. The punch ...
Lymphomas arise containing abnormalities of various differentiation stage-specific molecules. In the study reported here, we have shown abnormal up-regulation of germinal center B cell-associated GANP in various human lymphomas including mantle cell, diffuse large B cell, and Hodgkin lymphoma, by immunohistochemical analysis. To study the role of GANP in lymphomagenesis, we generated mutant mic...
Although it is known that B-cell lymphomas occur more frequently in immunocompromised patients, thus far such an association has not been clearly established for T-cell lymphomas. Of the 251 patients who were diagnosed with a T-cell non-Hodgkin lymphoma in our center between 1999 and 2014, at least 25 were identified in immunocompromised patients. Herein, we retrospectively analyzed the clinica...
INTRODUCTION Hodgkin Lymphoma (HL) is a group of lymphomas of mainly nodal origin with similar clinical and histological features (1). HL encompasses 95% of classical Hodgkin lymphomas (CHL) and the rest are of nodular lymphocyte predominant Hodgkin lymphoma (NLPHL). These two entities differ in their aetiology, clinical features, histopathological features, immunophenotype and molecular geneti...
Indolent non-Hodgkin lymphomas are characterized by a prolonged phase that is typically followed by a clinical progression associated with an accelerated clinical course and short survival time. Previous studies have not identified a consistent cytogenetic or molecular abnormality associated with transformation. The development of a transformed phenotype, evolving from the original low-grade co...
OBJECTIVE This study provides the clinical pathological characteristics of 1301 cases of pediatric/adolescent lymphomas in patients from different geographic regions of Brazil. METHODS A retrospective analyses of diagnosed pediatric lymphoma cases in a 10-year period was performed. We believe that it represents the largest series of pediatric lymphomas presented from Brazil. RESULTS Non-Hod...
Ocular annexes lymphomas are malignancies which occur in the conjunctiva, eyelids, lacrimal gland and orbit. Ocular annexes lymphoma is primarily a disease of older adults, with a slight female preponderance. Most lymphomas are low-grade B-cell lymphomas, with marginal zone lymphoma being by far the most common type. Marginal zone lymphoma typically involves the ocular annexes primarily, wherea...
Background & objective: The current study aimed to perform an immunohistochemical analysis of patterns of apoptotic and cell proliferative related protein expression in different histological grades and immune phenotypes of malignant lymphomas and other lymphoproliferative disorders Methods:This observational study was carried o...
