047. Endobronchial hamartoma diagnosed incidentally

Background Hamartoma, the most common benign lung tumor is often located peripherally in the lung parenchyma and rarely endobronchially: in this case it is diagnosed because of complications secondary to bronchial obstruction or because of chronic cough, hemoptysis and wheezing. We present a case of endobronchial hamartoma, discovered by chance.

人間ドックを契機に発見され閉塞性肺炎をきたした気管支内過誤腫の1例

気管支内過誤腫は比較的まれである．今回，人間ドックを契機に発見され閉塞性肺炎をきたし，区域切除で治療できたので報告する．症例は57歳，女性．人間ドックの胸部X線で異常を指摘された．胸部CTでは右肺S6に5cmの腫瘤を認め，肺門縦隔リンパ節は腫大し，肺癌が疑われ，当科紹介となった．紹介時は陰影が縮小，肺炎として抗菌薬治療で改善したが，閉塞性肺炎をきたし当科紹介となった．気管支鏡検査で右B6入口部にポリープ状の腫瘍を認めた．気管支鏡生検で過誤腫と診断されたが，治療に難渋する閉塞性肺炎のため手術適応と判断した．手術は後側方切開で右S6区域切除を施行した．腫瘍周囲は高度な炎症性肥厚，リンパ節の腫大を認めたが，B6を根部で切断し，内腔から腫瘍を確認して気管支断端を縫合閉鎖してS6区域切除を完了した．術後経過は良好で再燃は認めていない．

Two Cases of Diagnosis and Removal of Endobronchial Hamartoma by Cryotherapy via Flexible Bronchoscopy.

Although endobronchial hamartoma is a rare benign tumor, most patients with endobronchial hamartoma have respiratory symptoms such as obstructive pneumonia, hemoptysis, cough, or dyspnea due to bronchial obstruction. It can cause irreversible post-obstructive pulmonary destruction, thus early diagnosis and treatment is very important. Recently, there have been cases of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser and electrocautery procedures for bronchoscopic treatment of malignant or benign central airway obstruction with comparable therapeutic efficacy and few complications. Bronchoscopic cryotherapy is a newly developed technique for management of central airway obstruction. Moreover, it provides diagnostic methods with improving diagnostic yield and safety. We report two cases of endobronchial hamartoma, each diagnosed and definitively treated with bronchoscopic techniques. Endobronchial biopsy and removal was successfully performed by cryotherapy via flexible bronchoscopy without notable complications. Follow-up bronchoscopic examinations excluded residual or recurrent disease.

Endobronchial hamartoma is a benign tumour derived from peribronchial mesenchymal tissue. It is a form of intrapulmonary hamartoma and can cause irreversible pulmonary destruction due to bronchial obstruction. Early diagnosis and treatment is very important and endoscopic treatment is usually the first choice. In cases in which prolonged bronchial obstruction has produced irreversible lung destruction surgical, resection of the tumour is necessary. The aim of this study is to describe the clinicopathological characteristics of resected endobronchial hamartoma. Seven cases of endobronchial hamartoma, diagnosed in our institution between January 1995 and December 2009, were reviewed retrospectively. The patient population consisted of four males and three females with mean age of 53.7 years (41-68 years). The most frequent clinical presentation was obstructive pneumonia. Endoscopy and imaging showed an endobronchial mass in most cases. Surgical treatment consisted of atypical resection in one case, lobectomy in five cases and pneumonectomy in one case. Tumour size ranged between 0.5 and 3.5 cm. The diagnosis was confirmed in all cases by histological examination. The outcome was favorable in all cases. Endoscopic techniques are effective for the diagnosis and treatment of endobronchial hamartochondroma. Treatment should be prompt to prevent irreversible lung damage due to chronic obstruction and suppuration, in which case, pulmonary resection may be necessary.

Endobronchial hamartoma

Two cases of endobronchial hamartoma are reported, making a total of forty-two noted in the British and American literature. Although uncommon, hamartoma should be given consideration in any case manifesting bronchial obstruction.
