FDG PET/CT in Endobronchial Metastases from Extrathoracic Malignancies

Metastasis to the bronchus from extrathoracic malignancy is a rare event. We present 2 cases of endobronchial metastases from extrathoracic tumors with FDG PET/CT findings. One patient had a hypermetabolic endobronchial metastasis from breast cancer. The other patient had a hypermetabolic endobronchial metastasis from hepatocellular carcinoma. Both the endobronchial metastases were confirmed by bronchoscopic biopsy. These 2 cases indicate that FDG PET/CT is useful for detecting endobronchial metastases, and endobronchial metastasis should be included in the differential diagnosis of abnormal endotracheal or endobronchial FDG accumulation in patients with histories of malignant tumors.

Endobronchial Metastases of Renal Cell Carcinoma: A Complex Multidisciplinary Treatment

We report a case of endobronchial metastases of renal cell carcinoma, treated with rigid bronchoscopy and laser resection followed by bronchial artery embolization, in a 56-year-old Caucasian man, presenting with dyspnea, cough, and hemoptysis. Computed tomography of the chest and flexible bronchoscopy showed a large mass under the tracheal carina causing complete occlusion of the left main bronchus and subtotal (90%) occlusion of the right main bronchus, with saving of the homolateral lobar bronchi. The right main bronchus stenosis was removed during rigid bronchoscopy using neodymium-doped yttrium aluminum garnet laser and mechanical disruption. The procedure caused persistent bleeding, for this reason the right main bronchus was selectively intubated and bronchial arterial embolization was performed with arrest of the bleeding. After 3 days of Intensive Care Unit stay a bronchoscopy performed a day later documented the complete reopening of the right main bronchus. In conclusion, bronchial arterial embolization should be considered as another treatment option in endobronchial metastases of highly vascularized tumors such as renal cell carcinoma that often cause bleeding during their endoscopic resection.

Endobronchial Mass Developing 19 Years after Total Thyroidectomy due to Follicular Thyroid Carcinoma

Endobronchial metastasis from thyroid follicular carcinoma is a rare manifestation. We describe a case of 62-year-old woman who underwent total thyroidectomy due to thyroid follicular carcinoma 19 years previously. Computerized tomography and bronchoscopy suggested an endobronchial enhancing nodule in the right bronchus intermedius, resulting in right middle lobe (RML) and right lower lobe (RLL) collapse. A biopsy specimen showed thyroid follicular carcinoma identical to that taken from a specimen previously. She underwent metastectomy and high-dose radioactive iodine ablation therapy. To our knowledge, this patient represents the first case of endobronchial metastasis with a long past history of thyroid follicular carcinoma.

Endobronchial Metastasis from Adrenocortical Carcinoma

Lung parenchymal metastases are common manifestations; however, endobronchial metastasis is rare. We present herein a case of endobronchial metastasis from adrenocortical carcinoma. In the English language literature, this is the first case with such rare metastasis from adrenocortical carcinoma diagnosed antemortem. Although very rare, physicians should keep in mind the possibility of endobronchial metastasis in patients with a history of extrapulmonary malignancy including adrenocortical carcinoma.

Mucoid impaction secondary to mucin-producing metastatic adenocarcinoma of the cervix

Endobronchial metastases are an uncommon complication of malignant tumours. The vast majority are secondary to carcinoma of the breast, colorectum and kidney, or to melanoma. Occasionally, endobronchial tumours can result in partial or complete bronchial obstruction. Here, we describe an uncommon case of endobronchial metastasis of adenocarcinoma of the cervix causing mucoid impaction owing to mucous production by the tumour cells.

Endobronchial metastasis from prostate cancer

We report a case of endobronchial metastasis from prostate adenocarcinoma. A patient with a history of prostate cancer under complete androgen blockade presented to the respiratory department complaining of dyspnea and dry coughing. Flexible bronchoscopy showed multiple polypoid lesions in the tracheobronchial tree and the immunohistochemical studies on the biopsy specimen determined the diagnosis. The patient was treated with paclitaxel, estramustine phosphate and carboplatine, and experienced symptoms suppression. To our knowledge, this is the first case of endobronchial metastasis of a patient with androgen refractory prostate cancer without any evidence of extrathoracic metastasis. The current report also emphasises the need for a multidisciplinary approach for cases of endobronchial metastases, with the collaboration of pneumologists, urologists, pathologists and oncologists.

A Case of Endobronchial Metastasis from Renal Cell Carcinoma 7 Years after Nephrectomy

A distant metastasis from a renal cell carcinoma is quite common after a radical nephrectomy. For this reason, a5 year scheduled follow up is recommended. However, a distant metastasis 5 years after the resection is quite rare. We encountered an endobronchial metastasis from a renal cell carcinoma that was discovered 7 years after the radical nephrectomy, and did not present during the 5 year scheduled follow up regimen. We report this case with a review of the literatures.

Endobronchial Metastasis from Breast Carcinoma

A case of endobronchial metastasis from breast cancer is presented. The anatomopathological findings suggested the presence of another primary site with metastatic pleural effusion. It is imperative, however, to consider intrathoracic metastasis in patients with breast carcinoma and presenting symptoms such as cough, dyspnea with radiological findings of pulmonary nodules, pneumonitis, atelectasis, pleural effusion and hilar lymphadenopathy. Endobronchial metastasis is extremely rare: it may be the result of carcinomatous emboli through the blood stream or direct invasion of the bronchus by the adjacent carcinomatous lymphadenopathy. Pleural effusion in patients with intrathoracic metastasis does not necessarily evidence pleural metastasis.

A Case of Endobronchial Metastasis from renal Cell Carcinoma 10 Years After Nephrectomy

Pumonary metastases from renal cell carcinoma are common, but metastases in the large brohchi are uncommon and recurrence of renal cell carcinoma 10 years after primary resection is rare case. When endobronchial metastasis do present they usually simulate, clinically and radiologically, bronchial carcinoma. We report a 67-year-old man with endobronchial metastasis of renal cell carcinoma 10 years after radical nephrectomy with a brief review of the literature.

Endobronchial metastasis from rectal adenocarcinoma

A case of endobronchial metastasis 2 yr following treatment of rectal carcinoma is presented. Endobronchial metastases from extrathoracic primary malignancies are uncommon, the estimated frequency and possible mechanisms underlying this complication are discussed. The importance of recognizing possible endobronchial metastasis is in the approach to management and prognosis.

Mucinous Adenocarcinoma of the Prostate with Endobronchial Metastasis

Endobronchial metastases can manifest clinical symptoms and x-ray findings mimicking a centrally located bronchogenic carcinoma. The authors recently encountered a case of endobronchial metastasis from a mucinous adenocarcinoma of the prostate that was originally diagnosed as a primary bronchogenic carcinoma. The correct diagnosis was made on the basis of the morphologic similarities between the primary prostatic lesion and the lung lesion and was corroborated by immunohistochemical analyses.
