Pleomorphic adenoma usually occurs in the salivary glands but rarely in the trachea or bronchi. A 71-year-old man had abnormal shadows on a chest X-ray. Chest CT revealed one tumor in the right basal segment of the lung and another, in the left main bronchus. Bronchoscopic biopsy of the right tumor revealed well-differentiated squamous cell carcinoma. Right lower lobectomy and lymph node dissection were performed (pT2N0M0, stage IB). At the orifice of the left main bronchus, bronchoscopy identified a polypoid lesion nearly obstructing the airway. The lesion was resected with hot snare ablation. The histological examination revealed a mixture of epithelial and myxoid mesenchymal elements, characterized by ductal structures, squamous metaplasia, and cartilage tissue. The diagnosis was bronchial pleomorphic adenoma coexisting with squamous cell carcinoma of the lung.

“…10) In this patient, too, we successfully performed an endobronchial resection of the adenoma with an electrosurgical snare. In the absence of histological features of malignancy, such as necrosis and a high mitotic rate, 1) the remaining pleomorphic adenoma is unlikely to grow into a malignant phenotype.…”

“…In this report, significantly lower recurrence rates were indicated in the APC group in comparison to the non-APC (control) group (12). Therefore, additive coagulation by APC is usually administered at the site of a polypectomy in our institution (1,11). However, in the current case, since recurrence is rarely seen with fibroepithelial polyps, additive coagulation may not have been necessary, based on surveillance bronchoscopy (1).…”

“…Electrosurgical snare and APC are one of the modalities in interventional pulmonology. The immediate efficacy is now widely recognized (8)(9)(10)(11) (6 months). Recently, the adjunct use of APC has been reported to be safe and efficacious after a gastroenterological polyp resection (12).…”

“…Although endoscopic procedures are generally considered as palliative, they can be curative for benign lesions. [6][7][8][9][10][11][12][13][14][15][16] APC and EC have been widely used and accepted for the management of benign and malignant airway lesions. EC is defined as the application of a highfrequency electrical current via a probe to coagulate or vaporise tissue.…”

Endobronchial treatments are widely used for treating airway obstruction with the goal of relieving large airway obstructions caused by malignant or benign lesions. However, they may be curative in patients with benign conditions. We aimed to evaluate the usefulness of endobronchial argon plasma coagulation (APC) and electrocautery (EC) for treating patients with airway obstruction. Methods: We conducted a retrospective study in the bronchoscopy unit of a training and research hospital. Endobronchial treatment was carried out in 56 evaluable patients between 2007 and 2012. We used a rigid bronchoscope in 18 patients and flexible bronchoscope in 38 patients. General anaesthesia was administered to 32% (18 patients) patients. Bronchogenic carcinoma was seen in 43 patients, metastatic bronchial tumours in 1, and benign airway disease in 12. Obstruction sites were the trachea in 15 patients, main stem bronchi in 28 and lobar bronchi in 5. Eight patients had obstruction at multiple sites. Mean degree of obstruction was 84%. Immediately after the treatment, the mean degree of obstruction was 44%. Mean overall decrease in degree of obstruction was 39%. Post-tretament improvement of dyspnoea was excellent in 31 cases (55%) and moderate in 23 cases (41%); dyspnoea improvement was absent in 2 cases. Three complications (2 cases of respiratory insufficiency, 1 of mediastinal emphysema) were directly related to the endobronchial treatment. Conclusion: APC and EC are effective, rapid and repeatable techniques for treating endoluminal airway lesions and can effectively decrease dyspnoea.Keywords: Airway obstruction, Argon plasma coagulation, Electrocoagulation, Bronchoscopy ÖZET Semptomatik Hava Yolu Lezyonu Olan Hastalarda Bronkoskopik Tedavi Argon Plazma Koagülasyonu /ElektrokoterEndobronşiyal tedaviler, malign ya da benign lezyonların neden olduğu büyük hava yolu obstrüksiyonlarında palyatif amaçla yaygın olarak kullanılmaktadır.

Bu çalışmada hava yolu obstrüksiyonlarının tedavisinde endobronşiyal argon plazma koagülasyonu (APC) ve elektrokoterin (EC) yararlılığını değerlendirmeyi amaçladık. Çalışma retrospektif olarak bir eğitim araştırma hastanesi bronkoskopi ünitesinde yürütüldü. 2007-2012 yılları arasında 56 hastaya endobronşiyal tedavi uygulandı. On sekiz hastada rijid, 38 hastada fiberoptik bronkoskop ile işlem yapıldı. Hastaların %32 sinde (18 hastada ) genel anestezi uygulandı . Kırküç olguda bronş karsinomu, 1 olguda metastatik tümor, 12 hastada benign hava yolu darlığı mevcuttu. Onbeş hastada trakeada, 28 hastada ana bronşta, 5 hastada lober bronş düzeyinde, 8 hastada birden fazla yerde obstrüksiyon mevcuttu. Obstrük-siyon derecesi ortalaması %84 idi. Tedaviden hemen sonra saptanan obstrüksiyon derecesi ortalaması %44 idi. Obstrüksiyon derecesindeki azalmanın ortalaması %39 olarak bulundu. Tedavi sonrası dispnede düzelme 31 olguda(%55) "mükemmel", 23 olguda(41) "orta düzeyde" saptandı, 2 olguda dispnede düzelme görülmedi. Endobronşiyal tedavi ile iliş...
