title: [Primary non-Hodgkin's lymphoma of the breast].
abstract: Primary non Hodgkin's lymphoma of the breast (PNHLB) its an unusual presenting form of malignant breast diseases. Its estimated frequency is around 0.05-0.5% of all breast tumors. Three cases of PNHLB are presented. We analyse the characteristics of presenting features and also we discuss the therapeutic and prognostic implications. They can be initially confused with a typical breast carcinoma due to the unspecific clinical findings with the difficulty to obtain a definitive diagnosis based only on cytologic grounds. The therapeutic and prognostic consequences underlines the importance of immunohistochemistry in the diagnosis of PNHLB.
