Removal of glomus tumor in the lower tracheal segment with a flexible bronchoscope: report of two cases.
(66/201)
Tracheal glomus tumor is an extremely rare neoplasm resected mostly by open surgery or through rigid bronchoscopy. We report two cases presenting with polypoid masses arising from the tracheal membrane in the posterior wall of the lower tracheal segment. The tumor was removed by high-frequency electrocautery and flexible bronchoscopic argon-plasma coagulation, and follow-up bronchoscopy and chest CT did not reveal tumor recurrence 12 months after the operation. In patients with tracheal glomus tumor who have poor surgical tolerance or are not willing to receive an open surgery, flexible bronchoscopic tumor removal can be a good alternative to relieve the airway obstruction symptoms.

Solitary primary tracheal small-cell lung cancer causing acute respiratory failure: diagnosis and treatment.
(67/201)
Small-cell lung cancer often presents as an extensive cancer, and rarely as a solitary tracheal tumor. We report a 41-year-old male smoker with dyspnea and wheezing that was initially diagnosed as asthma and treated with bronchodilators. He was later intubated for acute respiratory failure, and computed tomography revealed a tracheal mass. Solitary primary small-cell lung cancer was diagnosed via bronchoscopic biopsy. The patient received bronchoscopic electro-surgery and was successfully extubated. Concurrent chemo-radiotherapy was performed due to the stage IV small-cell lung cancer. (+info)
Recurrent respiratory papillomatosis arising in trachea not affecting larynx.
(68/201)
Recurrent respiratory papillomatosis (RRP) is an infrequent benign neoplasm commonly involving the upper respiratory tract with laryngeal predilection. The diagnosis and treatment of this disease are challenging due to its nonspecific clinical presentations and recurrent nature. We report here a rare juvenile case of RRP arising in the trachea without laryngeal lesions. Our experiences indicate that a high awareness of RRP and proper consideration in the right clinical context are prerequisites for early diagnosis, and a combination of multiple treatment modalities should be considered as a feasible treatment regimen.

Management of a patient with an unexpected obstructing carinal mass.
(69/201)
Surgical procedures involving the airway or for mediastinal masses present considerable challenges for the anesthesiologist. Aside from the obvious technical challenges of providing ventilation, the anesthesiologist must share the airway with the surgeon. Careful and meticulous preoperative evaluation and preparation and intraoperative interaction with the surgical team is critical to assure control of the airway. We report a case of management of a patient with an unexpected near total obstruction of the airway from a carinal mass. (+info)

Tracheopathia osteochondroplastica complicated with thyroid cancer: case report and review of the literature in Japan.
(72/201)
A rare case of tracheopathia osteochondroplastica complicated with malignancy is reported. Further examination of hemosputum following thyroid cancer operation revealed an abnormal finding of the trachea, suggesting the recurrence of thyroid cancer. However, the serum level of thyroglobulin was within the normal range. In contrast, the findings of bronchofiberscopy and the histological analysis confirmed the presence of tracheopathia osteochondroplastica. Therefore, measurement of serum thyroglobulin level and the bronchofiberscopy procedure were valuable for the differential diagnosis of metastasis of thyroid cancer in this case. Additionally, case reports of tracheopathia osteochondroplastica in Japan are summarized. (+info)
