In histology, MUM1 serves as a critical biomarker for identifying and classifying certain types of lymphomas and other hematologic malignancies. Its expression is commonly assessed in tissue samples using immunohistochemistry (IHC) techniques. MUM1 is particularly useful in distinguishing between different subtypes of B-cell lymphomas, such as Diffuse Large B-Cell Lymphoma (DLBCL) and Plasma Cell Myeloma.
