label: Diffuse Large B-Cell Lymphoma Unclassifiable
label_lc: diffuse large b-cell lymphoma unclassifiable
description: "A biologic subset of diffuse large B-cell lymphomas (DLBCL) that do not overexpress the genes whose overexpression characterizes the germinal center B-cell-like and activated B-cell-like DLBCL.  Morphologically, these lymphomas are either immunoblastic or centroblastic.  Patients with this type of diffuse large B-cell lymphoma are reported to have a less favorable outcome, similar to those with an activated B-cell-like gene expression profile."
