title: [Pulmonary hamartoma as a differential diagnosis of breast cancer metastasis: case report].
abstract: We present the case of a 60-year-old female patient who had been in menopause for 14 years and presented a pulmonary nodule on chest X-ray diagnosed in the postoperative follow-up evaluation of breast cancer. The patient had a history of mastectomy and ipsilateral axillary lymphadenectomy for invasive ductal breast carcinoma, as well as of hormone therapy, chemotherapy, and adjuvant radiotherapy. After thoracoscopic nodulectomy, the frozen section analysis revealed a pulmonary hamartoma. Recent studies show that 75% of patients who undergo surgery for pulmonary nodules after a curative mastectomy for breast cancer present lung metastases, 11.5% present primary lung cancer, and 13.5% present benign lesions, including hamartoma.
