弥漫性小淋巴细胞型恶性淋巴瘤


恶性淋巴瘤呈弥散性,不见淋巴滤泡。低倍镜下已经看不到正常的淋巴结结构。淋巴结被小的淋巴瘤细胞浸润,浸润已经延伸到淋巴结的囊,浸润到周围的脂肪组织。诊断是:恶性淋巴瘤,小淋巴细胞型,弥漫性(也称为:“高分化”淋巴细胞淋巴瘤。
This pattern of malignant lymphoma is diffuse and no lymphoid follicles are identified. Under low power, note that the normal architecture of the lymph node is obliterated. The lymph node is replaced by an infiltrate of small (mature-appearing) neoplastic lymphocytes, and the infiltrate extends through the capsule of the lymph node and into the surrounding fat. The diagnosis is: malignant lymphoma, small lymphocytic type, diffuse (also known as: "well-differentiated" lymphocytic lymphoma).
