title: [Non-Hodgkin's malignant lymphoma with primary localization in the breast. Apropos of 2 cases: review of the literature].
abstract: The malignant non-hodgkinian lymphoma (M.N.H.L.) with pripary mammary localization is relatively rare, but deserves to be accounted for in the evaluation of breast cancers. The diagnosis of the primary localization in the breast responds to definite criteria, well established by Wiseman and Liao. On the other hand, the initial mammary localization is more frequent, revealing a hemato-sarcoma clinically silent until then, but with nodal spread (most of the time lumbo-aortic). The problem is to know whether it is possible, in front of a breast nodule, to evoke lymphoma in view of some clinical and paraclinical characteristics. An accurate pathological diagnosis (International Formula for clinical use of the National Cancer Institute-1982) and a minutious work-up for spread determination (AnnArbor Classification) represent the two essential aspects of the prognosis. It is advised to resort to surgical excision-biopsy in order to obtain an exact histology with analysis of immunological markers, rather than an extemporaneous examination which often leads to the wrong diagnosis of cancer and a mutilating and unnecessary surgery. Progresses in chemotherapy have greatly contributed to improve survival of these hematosarcomas with extranodal localization, which remain however a neoplastic disease with a disseminating tendency.
