[Infiltrating lobular breast cancer: histological and immunohistochemical characteristics].

ABSTRACT

Lobular carcinoma ranks second among most frequent tumors of the breast. Metastases to the lymph nodes and distant organs are one of the most important prognostic factors. 60% regional lymph node metastases were morphologically diagnosed during surgical removal of the tumor. Distant metastases rate was 1% at the beginning of the treatment and reached 10% within 5-year follow-up. Cases of secondary uterus and epiploon lobular carcinoma are rare and tumor location in the breast should be proved.
