Endobronchial Metastasis from Breast Carcinoma

摘要

Breast cancer is a common malignancy. Lung metastasis to the parenchyma can be seen in 20 to 50% of series. Endobronchial metastasis due to breast carcinoma is a rare finding in these patients and entitles a grim prognosis. Majority of patients have minimal or no pulmonary symptoms. We report a case on an endobronchial metastasis due to infiltrating Adenocarcinoma of the breast after four years of the initial diagnosis. Introduction The incidence of lung metastases is estimated to from 20 to 50% in nonpulmonary primary tumors. The incidence endobronchial metastasis is estimated to be approximately 2%. We report a case of EB metastasis four years after a treated breast carcinoma. Case Presentation An 85 year old African American female was admitted in September 2003 for uncontrolled hypertension. Her past medical history was remarkable for left breast carcinoma Stage T3NOMO in 1999, for which she underwent radical mastectomy. A recent parenchymal lesion in the right upper lobe was under investigation. Chest radiography on admission revealed a partial right upper lobe atelectasis. During hospitalization the patient developed acute respiratory distress requiring intubation. Computed Tomogram (CT) of chest confirmed a 4 x 5 cm hilar mass with mediastinal lymphadenopathy (Fig 1).
