Primary breast malignant lymphoma

Primary malignant lymphoma of breast (PMLB) is a malignant tumor that occurs in the lymphatic tissue of the breast. Primary breast malignant lymphoma is very rare and is often part of generalized lymphosarcoma, which may be related to less lymphoid tissue in breast tissue. Regarding the origin of breast malignant lymphoma, most scholars believe that the breast is a potential site of mucosa-associated lymphoid tissue. Primary breast lymphoma is a mucosa-associated lymphoid tissue tumor (MALT), which is related to the ducts around the mammary glands and the intralobular lymphatics. Tissue malignancy is related to tumor-like hyperplasia, and some people think that it is derived from naive and undifferentiated mesenchymal cells of vascular outer skin. The majority of breast malignant lymphomas are non-Hodgkin's malignant lymphomas. Under the microscope, breast malignant lymphomas have the same features as malignant lymphomas in other parts. Breast malignant lymphomas are characterized by diffuse distribution of tumor cells and single cell components. Most of them are diffuse large granulocyte type, diffuse large granulocyte type and diffuse small granulocyte type, other types are rare, there is no tendency to aggregate into nests, and abundant new thin-walled blood vessels can be seen. The tumor cells diffusely infiltrate between the leaflets and duct The catheter is not damaged, and there are no tumor cells and inflammatory exudates in the cavity.
