Gastric metastasis from breast carcinoma is uncommon and rarely encountered in our daily practice. We report a case of late gastric metastasis from previous infiltrating lobular carcinoma of the breast. The patient had extended disease-free interval of 22 years prior to metastasis. Gastroscopy and fluoroscopy showed changes appearing like linitis plastica of the body of the stomach. Computed tomography of the thorax and abdomen demonstrated pulmonary metastasis and mediastinal lymphadenopathy. Biopsy of the mediastinal lymph node and stomach lesion confirmed metastatic adenocarcinoma from breast carcinoma based on immunohistochemistry staining. Immunohistochemistry staining of both specimens revealed strong positivity for cytokeratin 7 and negative for cytokeratin 20.
