The patient was a 38-year-old woman. She had been followed-up by previous doctor about calcification in mammography. 3 months ago, a lump in her left breast was appeared and grown rapidly. She was performed core needle biopsy, and was diagnosed that the tumor was invasive ductal carcinoma of breast. She visited our hospital for treatment. The tumor was palpated as a hard mass measuring 50mm (MRI: 42mm) in the AC-region of left breast, also we touched some enlarged axial lymph nodes. Computed tomography showed a nodule of right lung 10mm in diameter, we suspected a metastases of breast cancer. Adjuvant chemotherapy was underwent. The chemotherapy was effective. We recognized partial response for the breast tumor and the lymph nodes metastases. However, the pulmonary lesion was showed stable disease. Video Assisted Thoracic Surgery was performed, the pathological diagnosis was hamartoma. After chemotherapy, the wide excision and axillary lymph nodes dissection. Now she was treated by endocrine therapy, with no recurrence 3 years after operation. We should consider a tissue diagnosis actively, when chemotherapy has the effect primary tumor but not observed in lung lesion.
