Figure 1From: IGH amplification in patients with B cell lymphoma unclassifiable, with features intermediate between diffuse large B cell lymphoma and Burkitt’s lymphoma Morphologic and immunophenotypic findings. (A) A pelvic mass core biopsy from case 4 showing sheets of medium to large sized abnormal lymphoid cells in a diffuse growth pattern. There is a monotonous appearance to the proliferating cells. A starry-sky pattern with tingible-body macrophages is seen (Hematoxylin-Eosin, original magnification × 400). (B) BCL-2 immunohistochemistry from the same case showing diffuse membranous and cytoplasmic staining of tumor cells (original magnification × 200).Back to article page
