[Pulmonary hamartoma as a differential diagnosis of breast cancer metastasis: case report].

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.
