Purpose: Lipomatous tumor occurred in hand is very rare. There is a broad spectrum of lipomatous tumors including lipomas, variants of lipomas, lipomatosis, liposarcomas and so on. We report the clinical features of 11 cases of lipomatous tumor which occurred in hand. Materials and Methods: Between 1992 and 2008, 11 cases were histologically diagnosed as lipomatous tumor in hand. We reviewed all medical records and clinical photographs retrospectively and ascertained recurrence by telephone interview. Results: Eight cases were ordinary lipomas. Three cases were angiolipoma, fibrolipoma and atypical lipoma respectively. Four cases occurred in finger, two cases in thenar area, two cases in hypothenar area, one case in palm, two cases in wrist. All cases were situated on volar surface. All patients complained of palpable masses. One patient with subungal angiolipoma felt pain. There was no neurologic sign or vascular symptom preoperatively. In one case, postoperative complication (hypoesthesia in $5^{th}$ finger) was developed. There was no local recurrence. Conclusion: In our study, lipomatous tumors occurred in hand did not recur. Patients mainly complained of feeling of lump. Pain was uncommon symptom. Postoperative complication was rare if operation was performed carefully.

Pneumomediastinum is a rare, but well recognized complication of bleomycin-induced lung toxicity. Spontaneous pneumomediastinum has to be considered as one of the causes when the dyspnea becomes aggravated in patients with bleomycin induced lung toxicity. We describe here two patients who suffered with germ cell tumor and they developed spontaneous pneumomediastinum without pneumothorax, and this was caused by bleomycin-induced lung toxicity.

A rare case of acute descending necrotizing mediastinitis(DNM) secondary to spontaneous rupture of hypopharynx is reported. Due to the right lower cervical abscess the patient had undertaken limited right anterior cervical drainage at other department. After transferring to our department he undertook combined wide cervical mediastinal drainage and mediastinal drainage via right thoracotomy. However mediastinal drainage was ineffective. So the second operation was performed and chest tubes were relocated. He had an uneventful postoperative course. As far as the cause of acute descending necrotizing mediastinitis was concerned, we couldn't find any literature in Korean or English except one case that dealt with spontaneous rupture of the hypopharynx.

Mediastinal parathyroid cyst is a very rare disease and is usually found incidentally. Surgical excision is the treatment of choice and recurrence is very rare when complete excision is done. A 71-year-old man was referred to our department because of 6$\times$5cm sized right superior mediastinal mass found incidentally on chest X-ray Surgical excision was performed and pathologic findings were confirmed as mediastinal parathyroid cyst. The patient has been followed up postoperatively without recurrence for 4 months up to now. We report a case of mediastinal parathyroid cyst.

Pleuropulmonary blastoma (PPB) is a rare intrathoracic neoplasm, found solely in childhood. The usual symptoms are dyspnea, chest discomfort, recurrent respiratory infections, fever, dry cough, and chest pain. The progress of PPB is usually aggressive and its progress is generally poor. Lymphatic spread to the hilar and mediastinal nodes can occur Distant metastasis is found in brain, bones, and intra-abdominal organs. Surgical resection is the treatment of choice. When the disease Is too extensive for surgical resection, neoadjuvant chemotherapy can be used. We report 2 cases of pleuropulrnonary blastoma in children successfully treated with multimodal therapy.

200 cases of pulmonary tuberculosis patients treated by surgical resection were anlized Bronchial resection margin was examined by microscopic study to detect submucosal tuberculosis granuloma. 6 cases of bronchopleural fistula that occurred after resection were also asnalized to fond any relation with submucosal granuloma. Among 200 cases, 19 cases (9.5%) showed submucosal granu- loma. Of the 19 cases, 2 cases (10.5%) developed ea ly and late bronchopleural fistula On the con- trary, only 2.2% developed in granuloma negative cases. Granuloma positive cases were mote fre- quently seen in preoperative sputum positive cases and showed incidence of residual pleural dead space resection.

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.

Spindle cell lipoma is a relatively rare adipocytic neoplasm that is easily mistaken for a liposarcoma, and is histologically characterized by a mixture of uniform spindle cells and mature fat cells. It occurs predominantly in male patients aged $45\~65$ years, and in most cases it arises in the subcutaneous tissue of the neck or shoulder. We report a case of a 45-year-old woman with spindle cell lipoma arising from the left pleural cavity.

Giant cell tumor is a benign but locally aggressive tumor with common recurrence. Most cases occur around the knee joint. Giant cell tumor of the foot is rare and very few cases involving the first metatarsal have been reported. Its characteristics and treatment in adult patients remain unclear. This paper reports a case of recurrent giant cell tumor at the first metatarsal that was excised surgically and subsequently reconstructed with non-vascularized fibula graft.

Posttraumatic psoudoaneurysrns of the subclavian artery are very rare. A 49-year-old woman who had been involved in a car accident ten years before presentation was initially diagnosed with a mediastinal tumor at a local clinic. Exploratory thoracotomy was performed for evaluation and treatment. During the operation, a hematoma was evacuated, and primary repair was undertaken to stop massive bleeding. Computed tomography angiography revealed a pseudoaneurysm of the left subclavian artery. The patient was treated with aneurysmectomy and end-to-end anastomosis. The postoperative course was uneventful.
