Diffuse large B-cell lymphoma, light micrograph. Diffuse large B-cell lymphoma is the most common type of lymphoma and accounts for about 35% of all cases of non-Hodgkin lymphoma. It is an aggressive malignancy and presents with rapidly enlarging lymph nodes or tumor masses at extranodal sites. There is diffuse proliferation of large to medium-sized lymphoid cells which can be classified into centroblasts and immunoblasts. Some cases have markedly pleomorphic anaplastic cells. This is a photomicrograph of diffuse large B-cell lymphoma of stomach in a gastric biopsy from a patient who presented with gastritis. The image shows immunohistochemical labelling with pankeratin. The gastric mucosa is strongly positive. The underlying lymphoma cells are negative. | |
