We experienced two cases of pulmonary hamartoma, which is the most common benign tumor of lung. But the hamartoma is rare disease, because the most neoplasm of the is malignant. The importence of pulmonary hamartoma is the necessity of differential diagnosis between lung cancer and benign tumor of the lung. Recently, the development of FNAB [Fine needle aspiration biopsy] shows accurate diagnostic results.

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.

Background : Pulmonary hamartomas are the most common form of benign tumors, occurring in approximately 0.2% of routine autopsies. However, only a few reports on the clinical characteristics of pulmonary hamartoma in Korea have been published. Materials and Methods : The charts, X-rays and pathological specimens of 29 pulmonary hamartoma patients who were diagnosed by a pathological examination from 1990 to 1999 at the Catholic Medical Center were retrospectively reviewed. Results : The peak incidence of the tumor occurred in the sixth decade of life (37.5%). Seventeen patients (58.6%) were asymptomatic and 12 patients (41.4%) had symptoms. Chest discomfort was the most common symptom (31.0%). A total of 25 tumors (86.2%) were parenchymal, and 4 (13.8%) were endobronchial. Twenty cases were in the right lung and 9 cases were in the left lung (approximately 1:2.2). The RLL was the most commonly involved lobe (31.0%). Calcification was noted in 5 cases(19.2%) on a plain X-ray and in 5 cases (29.4%) on chest CT. Accompanied neoplasms were observed in 2 cases. Twenty-four hamartomas (82.8%) were diagnosed by a surgical resection and 4 cases(13.8%) were diagnosed by a fine needle aspiration biopsy. Twenty-six hamartomas (89.7%) were managed by a surgical resection. The follow up ranged from 4 to 55 months (mean, 19.6 months) and no recurrent pulmonary hamartomas were noted. Conclusion : Pulmonary hamartoma is more common in females and more commonly in the right lung. Calcification was noted only in 19.2% on a plain chest X-ray and 29.4% on a chest CT. No recurrent hamartomas had developed during the follow up period.

The hemangioma, a benign proliferation of blood vessel, is the most common tumor of infancy and childhood. In many instances, the lesion probably represents a hamartoma or malformation rather than a true neoplasm. In the oral cavity, common sites are lips, followed by tongue, buccal mucosa and palate. Clinical characteristics appear as a flat or raised reddish-blue lesion and are generally solitary. They are classified on the basis of their histological appearance into capillary, mixed, cavernous or a sclerosing variety. A 6-year-old male of this case was referred to the Department of Pediatric Dentistry, Chonnam National University with a chief complaint of swelling lesion on gingiva. The strawberry appearance mass was detected by clinical examination on attached gingiva at the upper left primary lateral incisor and canine. Surgical excision and biopsy were carried out for histological examination and the lesion was diagnosed with a capillary hemangioma. The risk of recurrence after this therapy is rare, and there is no malignant transformation. Despite their benign origins and behaviour, hemangiomas in the region of oral cavity are always clinically important to the dental profession because of bleeding tendency.

Background: Pulmonary hamartomas are the most common form of pulmonary benign tumors, and they occur in approximately $2{\sim}5%$ of all pulmonary neoplasm. However, only a few reports have been published on the clinical characteristics of pulmonary hamartoma in Korea. Material and Method: The charts, X-rays and pathological specimens of 37 pulmonary hamartoma patients who were diagnosed by a pathological examination from January of 2000 to May of 2005 at the Catholic Medical Center were retrospectively reviewed. Result: The peak incidence of the tumor occurred in the seventh decade of life (32.4%), There were 23 men (62.6%) and 14 women (37.8%), with mean age of 55.6 years. Twenty-six patients (70.3%) were asymptomatic and 11 patients (29.7%) had symptoms. A total of 29 tumors (78.4%) were parenchymal, and 8 (21.6%) were endobronchial. Twenty cases (54.1%) were in the right lung and 17 cases (45.9%) were in the left lung. The right lower lobe was most commonly involved. Thirty-two (86.5%) hamartomas were diagnosed by surgical resection, 4 cases (10.8%) were diagnosed by bronchoscopic biopsy and 1 case (2.7%) was diagnosed by a fine needle aspiration biopsy. Thirty-four hamartomas (91.9%) were managed by surgical resection without complication. No recurrence or malignant changes were seen during the follow up period. Conclusion: Pulmonary hamartomas are most common in males during their fifth to seventh decade and they more commonly involve the right lung. No recurrence or malignant changes were seen during the follow up period.

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.

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.

The endobronchial hamartoma is a relatively rare benign tumor of the lung. The symptoms of the endobronchial hamartoma are produced by obstruction of the bronchus and its sequelae. This patient was 51 year old male and complained dypnea, cough and purulent sputum for 2 years. On bronchoscopic view, a yellowish pedunculated mass nearly total occluding right main bronchial lumen was found. Endoscopic biopsy revealed squamous cell metaplasia of the bronchial mucosa. The operation was done with the right pneumonectomy. The pathologic result of the operative specimen was endobronchial hamartoma arisen from the right upper lobe bronchus.

Hamartoma has been considered rare disease as a congenital malformation of a tumorous lesion since the original description by Albrecht in 1904. Pulmonary hamartoma is interesting to chest surgeon because of good result by surgical procedures and of slightly high incidence then another organs. It is characterized as lesion of very slow growing mass as peak incidence of age of 50 years age group and as sex ratio is 2:1. Especially endobronchial hamartoma is rarer than peripheral type. We had experienced a case of endobronchial hamartoma who has 53 years old male patient at right main bronchus and then treated by excision of tumor mass through right bronchotomy and preserving right lung except any lobectomy and pneumonectomy.
