An 89-year-old male was diagnosed with advanced gastric cancer during an upper gastrointestinal endoscopy for gastric polyp follow-up. Positron emission tomography revealed tumors with 18F-fluorodeoxyglucose(FDG)accumulation in the right lung and right breast. Incisional biopsy of the right breast tumor was performed and the tumor was diagnosed as primary breast cancer(ER: 90%, PgR: 70%, HER2: 1+, Ki-67: 17%). Since it was difficult to distinguish whether the lung tumor was primary lung cancer or metastasis, a bronchoscopic biopsy was performed. Histopathological examination revealed that the lung tumor was primary lung cancer. Thus, this male patient had simultaneous triple gastric, breast, and lung cancer. Total mastectomy was performed for the breast cancer under local anesthesia and adjuvant endocrine therapy was started. Stereo- tactic body radiation therapy(48 Gy/4 Fr/4 days)for lung cancer and partial gastrectomy for gastric cancer were subsequently performed. Although male breast cancer itself is rare, we experienced a very rare case of male breast cancer with simultaneous lung and gastric cancer.
