Localized fibrous tumor of the pleura is a rare condition. Most follow a benign course and they are round as an incidental finding during routine chest X-ray. A small proportion of these tumors are malignant and have characteristic clinical and histopathological features. In this paper, we report three cases of localized fibrous tumors of the pleura, one malignant associated with asymptomatic hypoglycemia, the others benign. In a malignant case, the tumor was reseated through thoracotomy and the hypoglycemia was relieved immediately. In two benign cases, tumors on small pedicles were resected using video-assisted thoracic surgical technique.

Leiomyoma of the bronchus is a very rare, benign tumor of the lung. We herein report a case of endobronchial leiomyoma which was treated by sleeve bronchoplasty without resection of the lung and without any complications. A 35-year-old man was admitted to our hospital complaining of stridor. Bronchoscopy revealed a round, hypervascular and smooth tumor nearly obstructing the left main bronchus at 1.5 cm distal portion from the carina. Biopsy was not performed for fear of massive hemorrhage. A sleeve resection of left main bronchus including the tumor and end-to-end anastomosis were performed. The histologic diagnosis was leiomyoma. The early diagnosis and appropriate surgical treatment to preserve the pulmonary function are important points of consideration.

Rhabdomyoma is the most common benign cardiac neoplasm in neonates. Most patients with rhabdomyoma experienced spontaneous regression. Yet some of them need surgical therapy because of hemodynamic problems of the heart such as arrhythmia, outflow tract obstruction and valvular dysfunction. We found multiple masses in both ventricles on the patient's fetal echocardiogram. Heart failure caused by severe left ventricular outflow tract obstruction quickly presented after birth. The mass interfering with the outflow tract was resected via the transaortic approach at the first day of birth. Postoperative echocardiography showed complete release of the outflow tract obstruction. He was discharged on the postoperative day 8. During the 3 years of follow up, we found that the sizes of the remnant masses had gradually decreased.

Benign metastasizing leiomyoma (BML) is a rare entity, characterized by the occurrence of multiple smooth muscle nodules in the lung with histologically benign leiomyoma, Both the uterine and pulmonary tumors have been found to express estrogen and progesterone receptors, which suggest that the pulmonary lesions represented metastases from leiomyoma. We experienced a 41-year-old female patient with BML and report here with the literature review.

The glomus tumor is a distinctive benign neoplasm with a small painful nodule, occurs most commonly in extremities but may be found elsewhere in the body. Its occurrence in the trachea or lung parenchyme has been recognized with extreme rarity and there has not been any report, to our knowledge, of its occurrence in the main bronchial glomus tumor. We report a case of a glomus tumor in the left main bronchus in a 67-year-old man who was presented with blood-tinged sputum and dyspnea, which was completely relieved by surgical resection.

Myoepithelioma is a benign tumor composed of sheets and islands of various proportion of spindle, plasmacytoid, epitheloid, and clear cells. We are reporting of a 38-year-old woman with an extremely rare neoplasm of the trachea, myoepithelioma. The patient had an right neck mass and diagnosed presumptively as the thyroid tumor with tracheal invasion. Resection and anastomosis of the trachea with partial thyroidectomy was done. The tumor was a well circumscribed mass with solid growth pattern and composed of spindle and epitheloid cells, which were positive for S-100 protein and smooth muscle actin. In electron microscopy, a large amount of microfilaments in the cytoplasm and layers of basement membrane-like materials in the intercellular spaces were observed, which are characteristics of myoepithelioma. Patient has been well for 8 months postoperatively.

Primary chest wall tumors originate from soft tissue, bone or cartilage of the chest wall and it comprises 1∼2% of all primary tumors. Resection of tumor is often indicated for chronic ulceration or pain, and long-term survival might be achieved after surgery depending on the histology and the surgical procedure. Material and Method: Retrospective study of 125 primary chest wall tumors (86 benign, 39 malignant) operated between Sep. 1976 to Mar 2001 were reviewed and their clinical outcomes were analyzed. Follow-up data were collected at the outpatient clinic. Result: All patients with benign tumors were treated by excision without recurrence or death, and most malignancies were treated by wide resection. Malignant fibrous histiocytoma and chondrosarcoma constituted 46.2% of the malignant neoplasm. There was no operative death. The overall 3-year survival for patients with primary malignant neoplasm was 76.0%, and the 10-year survival was 60.5%. All deaths were disease-related and the tumor recurred in 11 patients. There was no significant difference in survival between patients with resection margins less than 4 cm and those with resection margins greater than 4 cm. Conclusion: Chest wall resection offers excellent results for benign chest wall tumors and substantial long-term survival for malignant diseases. Safe resection margin of 4 cm or more did not correlate with the survival rate although the tumor recurrence correlated with poor survival.

Papillary fibroelastoma is a rare benign cardiac tumor with an elevated risk for embolization and most papillary fibroelastomas do not cause symptoms. In this report, we describe a case of previous undiagnosed masses of the aortic valve that were incidentally found on intraoperative transesophageal echocardiography during coronary artery bypass surgery. Upon surgery, masses were found on the left and right aortic cusps and the pathological findings were consistent with a papillary fibroelastoma.

A giant cell tumor of bone is a benign bone tumor, but has very high local recurrence rate and, very rarely metastasizes to the lung or a distant area. We report a case of a 29-year-old male patient presenting with a metastatic giant cell tumor of the soft tissue of the chest wall, who underwent a total resection of the radius for recurrence of the giant cell tumor. The tumor was not related to any bony structure of the thorax. We resected the tumor with a wide surgical margin. No evidence of malignancy was seen in the frozen and permanent pathological report.

A 40-year-old woman was admitted to the hospital due to a palpable tumor on an anterior chest wall. The tumor was diagnosed with a nodular fasciitis. It is a rare benign soft-tissue tumor which has a characteristic referred to as proliferation of fibroblast, and a surgical removal is the best effective treatment. Therefore, we report this case with documents and considerations after the surgical removal.
