PRIEGO J, PABLO et al. Peritoneal carcinomatosis secondary to lobular breast cancer. Rev Chil Cir [online]. 2007, vol.59, n.3, pp.223-228. ISSN 0718-4026.

Introduction: Although breast cancer most frequently metastasizes to the linfatic nodes, bones, lungs and liver, it can also affect the gastrointestinal tract, peritoneum and gynecology organs. Material and methods: We describe three cases of peritoneal carcinomatosis secondary to metastatic dissemination of an infiltrating lobular breast cancer. In the three cases diagnosis was realized many years after the delivering of the primary tumour and in two cases we observed tumour remission at one and four years respectively after administration of chemotherapy and hormonal therapy postoperative. Conclusion: Peritoneal carcinomatosis in breast cancer is rare, but when appears it is usually secondary to infiltrating lobular breast cancer with positive hormonal receptors. The symptoms are unspecific and normally exists a long term after the initial diagnosis of the tumour, therefore in many cases it is difficult of differentiate between a primary tumour of peritoneal cavity and metastases of a breast cancer. The diagnosis is fundamental, because with the chemotherapy and the hormonal therapy, partial or complete tumour remissions, have been described during long time
