Metastasizing signet ring cell carcinoma of the stomach-mimicking bilateral inflammatory breast cancer.

We describe a case of unusual metastases of a gastric carcinoma to the female breast, there likely to be an inflammatory breast cancer. A 46-year-old woman was admitted to our institution with bilateral breast tumors, not typical for a breast cancer as tumor growth was synchronically bilateral within a very short period of only 2 months. The woman underwent a palliative gastrectomy 3 months before for a poorly differentiated adenocarcinoma with signet ring appearance presenting as linitis plastica. At the time of the first operation the mammary glands were not suspicious. Breast biopsies assured metastases of the gastric cancer. In addition to this case report, a short overview of the literature concerning the very few cases of metastases of gastric cancer to the breast is given. Copyright 1999 Academic Press.
