• Non-small cell lung carcinoma
• Metachronous breast metastasis
• Adenocarcinoma

Breast metastases from an extramammary primary tumor are very rare and the prognosis for such patients is generally poor. We report here on a case of a 42-year-old female with metastasis of non-small cell lung cancer to the breast, and she is now being followed up on an outpatient basis. In 2004, she presented with a solitary pulmonary nodule in the left lung, and this lesion had been noted to have gradually increased in size over time. The final pathological diagnosis was adenocarcinoma, and the diagnosis was made by performing percutaneous needle aspiration and lobectomy of the left upper lobe. Adjuvant chemotherapy and radiotherapy were given. Unfortunately, a nodule in the left breast was noted three years later, and metastatic non-small-cell lung cancer to the breast was diagnosed by excisional biopsy. Making the correct diagnosis to distinguish a primary breast carcinoma from a metastatic one is important, because the therapeutic plan and outcome for these two types of cancer are quite different.
