BACKGROUND Survivors of childhood leukemia and lymphoma experience high risks of second malignant neoplasms. We quantified such risk using a large dataset from 13 population-based cancer registries. METHODS The registries provided individual data on cases of leukemia, Hodgkin lymphoma, and non-Hodgkin lymphoma occurring in children aged 0-14 years and on subsequent second malignant neoplasms ...
Feline malignant lymphoma occurs commonly in domestic cats and may serve as a model for non-Hodgkin's lymphoma in humans. Several studies have suggested that smoking may increase the risk of non-Hodgkin's lymphoma. To evaluate whether exposure to household environmental tobacco smoke (ETS) may increase the risk of feline malignant lymphoma, the authors conducted a case-control study of this rel...
Among head and neck malignancies, lymphoma is the second most frequent cause. They can develop in the head and neck lymph nodes or as extranodal determinations. The onset of malignant lymphoma outside of lymph node registers increasingly frequent, currently over 30% of malignant lymphoma are diagnosed as taking place outside the lymph nodes. The aim of this paper is bringing in discussion and t...
Diffuse large B cell lymphoma (DLBL) of the breast is a rare subtype of breast tumor, the diagnosis of which is based on the cytological and histopathological features of this unique neoplasm. A 28-year-old woman noticed a mass in her right breast. It could not be definitely diagnosed clinically by diagnostic imaging (mammography, ultrasonography), so malignant tumor not otherwise specified was...
Neurolymphomatosis is a rare manifestation of non-Hodgkin lymphoma characterized by infiltration of peripheral nerves, nerve roots, plexus and cranial nerves by malignant lymphocytes. This report presents positron emission tomography/computed tomography (PET/CT)imaging with 2-deoxy-2-18F-fluoro-D-glucose (18F-FDG) in 3 cases of non-Hodgkin lymphoma with nerve infiltration, including one newly d...
A case of malignant lymphoma associated with complete heart block in a 30-year-old woman is reported. The patient progressively deteriorated despite temporary pacing and died 24 days after being admitted. Microscopic examination of the heart revealed marked infiltration by lymphoma cells in the atrioventricular node and the bundle of His. A diffuse lymphoma (large cell type, B cell) was diagnos...
Pulmonary mucosa-associated lymphoid tissue-derived (MALT) lymphoma is a rare disease. This disorder is considered to be a model of antigen-driven lymphoma, which is driven either by autoantigens or by chronic inflammatory conditions. Low-grade B-cell MALT lymphoma may develop from a nonneoplastic pulmonary lymphoproliferative disorder, such as lymphocytic interstitial pneumonitis (LIP). A rece...
OBJECTIVE The study was designed to answer the question whether a particular (slow/fast) acetylator phenotype is a risk for malignant lymphoma patients. Differences in acetylator phenotypes were previously described in urinary bladder and colorectal carcinoma patients compared to controls. Addressing this issue may help understanding the possible role of xenobiotics' metabolism in the pathogene...
PURPOSE In this study we aimed to compare the flow cytometry (FC) results of patients with B cell lymphoma, T cell lymphoma, Hodgkin's lymphoma, granulomatous inflammation and reactive lymph node and investigate the role of FC in malignant or non malignant conditions. METHODS Ninety patients were divided into 5 groups according to histopathology results. Patients were compared according to cy...
AIM To report a case of metastatic small-cell neuroendocrine carcinoma presenting as an isolated choroidal mass and initially misdiagnosed as a circumscribed choroidal hemangioma. METHODS The clinical history, fundus findings, imaging, cytology and immunohistochemical features are described. RESULTS An otherwise healthy 66-year-old man was referred for a left nasal scotoma and a diagnosis o...
