Abstract Approximately 25% of female cancer cases are breast cancer in India, with high incidence between 25 yrs and 40 yrs. Bilateral breast cancer is usually rare and presence of gastric metastasis is even rarer. When such patients presents with signs and symptoms of metastatic disease as the chief complaint, it is very difficult to find out primary. We report a case of a forty-year-old woman, who presented with complains of dysphasia and vomiting after having meals since one month. Her Endoscopy and biopsy outside suggested gastric carcinoma. On Preliminary examination at our centre revealed that the patient has bilateral breast lumps with multiple lymph nodes in bilateral cervical and axillary regions. Multiple biopsies were taken and IHC was performed from both gastric and breast tissue which concluded our final diagnosis as infiltrating ductal carcinoma breast with gastric metastasis.
