Endobronchial metastasis from primary papillary serous carcinoma of the peritoneum.
A 59-year-old woman was admitted to our hospital with a left lower lobe opacity and mediastinal shift on the chest X-ray. She had been complaining of intermittent nonproductive cough and exertional dyspnea. Chest computed tomography (CT) showed an endobronchial tumor of the left main to the lower bronchus, atelectasis of the left lower lobe, and mediastinal shift. Bronchoscopy revealed a polypoid tumor at the distal portion of the left main bronchus that occluded the bronchus. Biopsy specimens from the endobronchial tumor were shown to be serous papillary adenocarcinoma. Since the patient had been treated surgically for primary papillary serous carcinoma of the peritoneum (PSCP) 10 years earlier, immunohistochemical examinations were performed. The diagnosis of endobronchial metastasis of PSCP was confirmed by immunohistochemical staining with cancer antigen 125 (CA125), vimentin, and Wilms tumor-1 (WT-1). This is a rare case of endobronchial metastasis from PSCP.
