Familial lymphoma is uncommon and is usually associated with various forms of hereditary immunodeficiencies. Primary gastric lymphomas that occurred in three adults from the same family, who had no overt immunodeficiency or cancer of non-lymphomatous origin, are reported. Two sisters presented with a low grade lymphoma of the mucosa associated lymphoid tissue type. Their father presented with a...
Cases of low-grade B-cell lymphoma presenting primarily in the bone marrow are rare, and its clinicopathology remains unclear. We retrospectively examined patients with low-grade B-cell lymphoma presenting primarily in the bone marrow. Fourteen patients met the inclusion criteria, including 5 with lymphoplasmacytic lymphoma (LPL), 3 with chronic lymphocytic leukemia/small lymphocytic lymphoma, ...
BACKGROUND Helicobacter pylori (H. pylori) infection has been postulated to be a pathogenetic factor in gastric lymphoma. However, the etiological factors for gastric lymphoma could vary in different populations. MATERIALS AND METHODS We looked for histological evidence of H. pylori infection in 53 gastrectomy specimens from Hong Kong Chinese patients with primary gastric B-lymphoma. We also ...
Waldenstrom's macroglobulinemia/lymphoplasmacytic lymphoma (WM/LPL) is a low-grade B-cell non-Hodgkin's lymphoma with an indolent clinical course. Higher-grade non-Hodgkin lymphoma (NHL) and therapy-related myelodysplasia/acute leukemia (t-MDS/AML) have been reported in patients with WM/LPL in previous studies. However, only two cases with WM/LPL were reported to develop to Hodgkin lymphoma (HL...
This report presents a case of collision tumors of low-grade B-cell lymphoma and adenocarcinoma in the sigmoid colon of an 81-year-old man. All surgically resected regional mesenteric lymph nodes were found to be occupied by low-grade B-cell lymphoma, and one lymph node showed the presence of adenocarcinoma. Low-grade B-cell lymphoma was also observed in the resected spleen. Moreover, concurren...
AIMS To investigate whether immunohistochemical staining using p53 and/or bcl-2 distinguishes between florid Hashimoto's thyroiditis and low grade mucosa associated lymphoid tissue (MALT) lymphoma of the thyroid. METHODS Ten cases of Hashimoto's thyroiditis and eight of primary thyroid lymphoma were stained with monoclonal antibodies directed against p53 and bcl-2. RESULTS In Hashimoto's th...
marginal zone lymphoma (mzl) accounts for between 5% and 17% of all non-hodgkin lymphomas (nhl). w e reported a rare case of marginal zone lymphoma presenting with bilateral ear erythema and swelling. the case was a 79-year-old man who suffered from progressive bilateral ear erythema and swelling since 2 years ago. physical examination was remarkable for erythmatous, edematous and non-tender au...
AIMS To investigate the immunohistochemical expression of p53 protein in non-Hodgkin's lymphomas (NHL) and its relation to that of c-myc p62 oncoprotein and proliferating cell nuclear antigen (PCNA). METHODS Paraffin wax embedded tissue from 90 non-Hodgkin's lymphomas (72 B cell and 18 T cell) was stained immunohistochemically for p53 protein, c-myc p62 oncoprotein, and PCNA using the monoclo...
