Endobronchial metastasis from renal cell carcinoma: Report of a case

Abstract

A case of endobronchial metastasis from renal cell carcinoma developing 5 years after a right nephrectomy in a 63-year-old man is reported. Bronchoscopic examination performed after the patient presented with hemoptysis showed a polypoid tumor obstructing the entrance to the left upper bronchus. A snare was introduced through a bronchofiberscope to remove the endobronchial tumor, following which his atelectasis improved remarkably and his hemoptysis resolved. No side effects were observed. Electrosurgical snaring proved useful as palliative treatment to relieve bronchial obstruction due to an endobronchial metastasis in this patient.

Bronchial Artery Embolization before Interventional Bronchoscopy to Avoid Uncontrollable Bleeding: A Case Report of Endobronchial Metastasis of Renal Cell Carcinoma

“…Other conventional procedures, chemotherapy and local radiotherapy, were excluded from the patients' intraluminal-therapeutic strategy because these treatments were not thought to be effective against metastatic lesions of renal cell carcinoma. Sakumoto et al reported the usefulness and safety of diathermic snares in palliative treatments for EBM of renal cell carcinoma (16). Although diathermic snares are useful in cases of polypoid lesion with a small base attachment, the instruments are not always useful for flat lesions or for those with large base attachments (17).…”

“…In these cases, other techniques, including electrocoagulation or the use of lasers, may be more effective and convenient (3). Sakumoto et al discussed bleeding as the most serious complication in their report (16), and sometimes a blood transfusion was needed for patients suffering gastrointestinal metastasis of renal cell carcinoma (18). Thus, in the endoscopic treatments of airway obstructions due to metastatic renal cell carcinoma, preparations for massive bleeding are essential.…”

Endobronchial Metastasis from Renal Cell Carcinoma as a Reason for Recurrent Pulmonary Infections

“…Most common symptoms are cough, hemoptysis, dyspnea and wheezing in the context of recurrent pulmonary infections due to local atelectasis [1][2][3][4][5]7]. In rare cases, patients with EBM may be totally asymptomatic [10].…”

Thoracic Metastasis From Renal Cell Carcinoma

“…[2][3][4][5] This case, while demonstrating some of the potential appearances of intrathoracic metastases from renal cell carcinoma that an interventional bronchoscopist may encounter, also serves to extend this warning to EBUS-TBNA of nodal metastases. There are several case reports that warn against the risk of bronchoscopy in the presence of endobronchial metastases from renal cell carcinoma, in particular the risk of hemorrhage.…”
