Breast cancer metastatic to the gastric wall

Most gastric tumours are primary carcinomas, but other tumours, including metastatic lesions, may also be seen. The most frequent primary location of a gastric metastasis is the breast. We present a case of a 55-year-old woman, in whom the mammary primary remained clinically unnoticed, and the patient was diagnosed with gastric cancer and treated as such. Only after gastrectomy was the proper diagnosis established. Although rare, metastatic carcinoma should be taken into account in differential diagnosis of less usual patterns gastric tumours.
