From 1992 to 2000, we identified 23 lymph node biopsies with focal germinal centers (GCs) containing centrocytes staining strongly for bcl-2 protein, whereas most of the remaining lymph node showed bcl-2-negative follicular hyperplasia. We propose the designation in situ localization of follicular lymphoma (FL) for this phenomenon. In 2 additional cases,(More)
BACKGROUND Although the gastrointestinal tract is the most common site of extranodal non-Hodgkin's lymphoma (NHL), primary small intestine lymphomas remain relatively rare, especially localized low-grade follicular B-cell lymphomas. When lymphomas do occur at this site, most are high grade and require aggressive therapy. We report three cases of small(More)
Two kinds of HL-60 cell growth suppressor present in human fetal liver were studied. One is the already known arginase, which showed nonspecific suppression on the growth of HL-60 cells and human granulocyte-macrophage progenitors (CFU-GM), and the other, a new species of suppressor with the characteristics of lower molecular weight (less than 10,000(More)

One is the known arginase which shows non-specific suppression on the growth of HL-60 cells and human granulocyte-macrophage progenitors (CFU-GM), and the other, a new species of suppressor with a lower molecular weight (less than 10,000 daltons), shows preferential(More)
