Introduction. Non-Hodgkin Lymphoma (NHL) is a heterogeneous group of lymphoid malignancies with significant clinical, morphological, and genetic diversity. The most common subtype, Diffuse Large B-Cell Lymphoma (DLBCL), typically involves lymph nodes, spleen, or bone marrow, but can also present at extranodal sites. Extranodal involvement occurs in about 30% of cases, with the skin being a frequent site. Breast involvement, however, is rare.
