Primary Diffuse Large B-Cell Non-Hodgkin's Lymphoma of the Thoracic Spine Presented Initially as an Epigastric Pain.

Non-Hodgkin's lymphoma (NHL) compromises the vast majority of lymphomas and predominantly takes on the form of B-cell lymphomas. More specifically, 30% of all newly diagnosed cases of NHL in the United States (US) are of diffuse large B-cell lymphoma (DLBCL) type, making it the most prevalent form of NHL in the US. Arising from either nodal or extra-nodal lymphatic tissue origin, DLBCL is an aggressive tumor which is fatal if left untreated.
