In comparison to parenchymal hamartoma, endobronchial hamartoma is rare benign neoplasm of the lung. Most parenchymal hamariomas are asymptomatic and are found incidentally. However, endobronchial hamartomas are frequently discovered through respiratory symptoms as a result of bronchial irritation or obstruction. A 47-year-old male patient was admitted to our hospital due to dry cough f month prior to admission. On bronchoscopic examination, a polypoid mass was found completely obliterating the anterior segmental bronchus of the left upper lobe. We report a case of endobronchial chondroid hamartoma, which was resected by anterior segmentectomy of the left upper lobe.

Background: Pulmonary hamartomas are benign tumors that occur in the parenchyma or in the bronchi. They present as a solitary pulmonary nodule(SPN) or as a cause of bronchial obstruction. The incidence, once minimal, is increasing in Korea. To get clinical spectrum about the tumor, we analyzed all the reported cases in Korea since 1964. Methods: We reviewed the clinical, radiological and pathological findings of 13 patients of intrapulmonary or endobronchial hamartomas in Severance Hospital and of 38 reported cases in Korea published in literatures from 1964 to 1992 retrospectively. Results: Including 17 endobronchial hamartomas, 54 cases were studied. There were 25 men and 29 women, with a mean age of 47.2 years; 45.3 years in endobronchial type and 51.3 years in parenchymal type. Pulmonary symptoms were present in 8 patients (22%) of intrapulmonary type and in all patients of endobronchial type: cough (65%), dyspnea (53%), sputum (35%), fever (29%) in order. On chest X-rays, atelectasis was seen in 10 patients (59%) in endobronchial type; but SPN was noted in 36 patients (97%) of intrapulmonary type. Calcification was present in 7 intapulmonary hamartomas (23%); but is in 2 endobronchial hamartomas (12%). The diagnostic yield was 6 out of 14(43%) in endobronchial ones; 4 out of 7(57%) in intrapulmonary ones. Fifty patients underwent operations as follows: lobectomy (28), enucleation (8), resection (8), bilobectomy (4), pneumonectomy (2). The hamartomas were 1.2 times more common in the right lung; mean transverse diameter at the time of operation was 2.3 cm in endobronchial type, 3.8 cm in intrapulmonary ones. Chondroid components were present in 11(65%) of 17 endobronehial ones but in 30(91%) of 33 intrapulmonary hamartomas. No malignant changes were seen perioperative period and up to early 1993. Conclusion: The younger age in endobronchial hamartomas, the preponderance of the female sex and the more incidence in the right lung, and the diagnostic choice of lobectomies were different from the studies of the Western countries.

Pulmonary hamartoma is a common benign tumor of the lung, but endobronchial hamartoma is a rare tumor. Although bronchoscopic rcemoval or removal by bronchotomy or sleeve resection with preservation of the lung may be possible, when irreversible lung damage has occurred because of chronic obstruction and pneumonitis, pulmonary resection may be indicated. We herein report a case of endobronchial hamartoma which was treated by left upper lobectomy. A 42-year-old female with 3-week history of cough and left chest pain visited our hospital. Bronchoscopy showed total occlusion of the orifice of the left upper lobe bronchus by a lobulated endobronchial tumor and bronchoscopic biopsy was failed due to bleeding. A left upper lobectomy was performed because of severe consolidation of the left upper lobe by chronic obstruction. The patient was discharged on postoperative 14th day.

Hamartoma is rare but the most common benign neoplasm in the lung. However endobronchial lipomatous hamartoma has been rarely reported. A 73-year-old male patient was admitted to our hospital due to hemoptysis 1 month prior to admission. On bronchoscopic examination, a large pedunculated endobronchial mass right upper lobar bronchus. The endobronchial mass was enucleated by bronchotomy that is no evidence of malignancy in frozen specimens. We report a case of endobronchial lipomartous hamartoma which was resected by bronchotomy.

Hamartoma is one of the most common benign lung tumors. Most of them are located in the lung parenchyme, but very rarely it can originate endobronchially. Endobronchial hamartoma may cause irreversible lung damage due to the bronchial obstruction if it is not diagnosed and treated properly. The most frequent clinical features are hemoptysis and obstructive pneumonia. Transbronchial endoscopic surgery is a good therapeutic choice and is recommended first for patients who have resectable small endobronchial hamartoma. Here, we report a case of endobronchial hamartoma treated with rigid bronchoscopy and various microforceps with a review of the literature.

A hamartoma can be defined as a developmental malformation composed of tissue that normally constitute the organ in which the tumor occurs, but in which the tissue elements, although mature, are disorganized. Hamartoma is one of the most common benign lung tumors. Most of them are located in the lung parenchyme, but very rarely it can originate endobronchially. There is no case report of multiple endobronchial hamartomas in Korea. We report a case of multiple endobronchial hamartomas in a 63 year old woman with a review of the literatures.

Inflammatory myofibroblastic tumor was widely known as inflammatory pseudotumor, commonly developed as a solid mass in lung. The endobronchial inflammatory myofibroblastic tumor is a very rare case where only a few cases have been reported. We report a 13-year-old girl who had coughing for 5 months. The simple chest X-ray and computued tomography of the chest revealed a mass which obstructed the right lower lobe bronchus and pneumonic consolidation. The fiberoptic bronchoscopic finding was mostly gelatinous, gray-yellowish mass that obstructed the airway of right lower lobe bronchus nearly, and was considered as a chondroid hamartoma pathologically. Right lower lobectomy of lung was performed. The mass was confirmed as a endobronchial inflammatory myofibroblastic tumor The patient was discharged without complication and with outpatient followup.

Endoscopic removal is acceptable for the treatment of endotracheal/endobronchial mass, because it is less invasive in high-risk patients and a conservative procedure for benign tumors. Two benign tumors in the lumen of the trachea (pure lipoma) and in the intermediate bronchus (hamartoma) were completely eradicated by our procedures, which involved diathermic snaring and residual mass removal with biopsy forceps under the guidance of fiberoptic bronchoscopy. No tumor recurrence was evident after extended follow-up (6 years for endotracheal lipoma and 2.5 years for endobroncheal hamartoma). Our method is safe and less invasive for the patient and provides the surgeon with better view during procedure.

The hamartoma is the commonest benign tumor of the lung and proved incidentally as asymptomatic coin lesion on routine chest radiologic examination, but has very low incidence, especially in endobronchial origin. The authors experienced a case of coincidental with intrapulmonary and endobronchial hamartoma. The patient, a 60-year-old man, a farmer, was admitted due to coughing and fever. Preoperative diagnosis was achieved by flexible bronchoscopic biopsy and managed by right middle lobectomy. Three lobulated masses were palpable in the right middle lobe. He was discharged on 15th postoperative day, without problem.

Background: Tracheal hamartoma is a very rare cause of upper airway obstruction. Its clinical features can mimic medical conditions, such as bronchial asthma, chronic bronchitis, and so on. Case; This report presents the case of a 65 year old man whose major symptom was dyspnea. We found a tumor in his distal tracheal lumen, and the tumor was removed with success using rigid bronchoscope. The tumor was histologically proven to be a hamartoma, and his symptoms were much improved. Conclusion: It is important to distinguish it from other conditions because medical management is often not helpful. Surgical correction-with or without thoracotomy-is inevitable.
