Localized fibrous tumor of pleura is submesothelial origin and related terms with localized mesothelioma, giant sarcoma of visceral pleura, post-inflammatory tumor of the pleura, pleural fibroma, submesothelial fibroma. This tumor is rare. We experienced a case of localized fibrous tumor.This 66 years old female was admitted with 2 years left persistant flank pain and mild dyspnea. Chest X-ray and CT scan showed a 12x10cm well-defined huge mass in the left subpulmonic area, and not metastatic lesion of any organs.Exploratory thoracotomy was done and a 14x10x8cm [650gm weight] sized mass was excised.The patient was discharged without any complications postoperatively.

Localized or solitary fibrous tumor (SFT) of the pleura has been classified as a type of mesothelioma, arising from the submesothelial connective tissue cells. The preoperative diagnosis of the tumor at the cytologic or histologic level is very important for the proper handling of the lesion. This preoperative diagnosis is now possible by means of the advance in the transthoracic fine needle aspiration biopsy (FNA) techniques and in the very experience of the cytopathologists. We describe FNA cytologic feature of two cases of SFT arising from the pleura. Cytologic, histologic, immunohistochemical, and electron microscopic characteristics of pleural SFT are discussed. The tumor cells of SFT are spindle or oval in shape with a variable amount of cytoplasm. They are arranged in irregular trabeculae intimately associated with capillaries. A unique cytologic feature observed in this tumor is that thick, eosinophilic, amorphous collagen bundles are scattered between tumor cells.

A 44-year-old man was transferred to our department for mediastinal mass. He had suffered from only an easily fatiguable condition for 1 month. A physical examination and laboratory finding of the patient disclosed no abnormality. A chest radiograph showed a soft tissue tumor in the posterior mediastinum. It was well circumscribed and ovoid. Invasions to adjacent organs were not seen. Therefore it was though the 5th intercostal space. The tumor mass was attached to the visceral pleura of the right upper lobe by a pedicle and this pedunculated tumor laid entirely within the pleural cavity. Excision of the tumor which measured 7$\times$7$\times$3cm was done easily. Pathologic studies confirmed the diagnosis of localized fibrous tumor of the pleura. Localized fibrous tumor of the pleura is rare, This tumor along ith the evidence from ultrastructural and immunohistochemical studies has led most researchers to conclude that localized fibrous tumor is not of the mesothelial origin but arises in the submesothelial connective tissue.

Purpose To identify the imaging features indicative of sarcoid-like reactions in patients with intrathoracic lymphadenopathy after complete remission of malignancies. Materials and Methods This study enrolled five patients with histopathologically confirmed sarcoid-like reactions that developed after cancer remission. The clinical features and findings of CT and ¹⁸F-fluorodeoxyglucose (FDG) PET/CT were assessed. Results The underlying malignancies included breast, nasopharyngeal, colon, and endometrial cancer and lymphoma. The time intervals between complete remission of malignancy and the diagnosis of sarcoid-like reaction ranged from 6 to 78 months. CT findings of sarcoid-like reaction included bilateral hilar and mediastinal lymphadenopathies (n = 5), pulmonary nodules (1-15 mm) with peribronchovascular, fissural, or subpleural distribution, and interlobular interstitial thickening in the lungs (n = 4). ¹⁸F-FDG PET/CT revealed hypermetabolic uptake in the mediastinal and hilar lymph nodes and both lungs in the absence of extrathoracic uptake (n = 3). The sarcoid-like reactions resolved in all patients after corticosteroid treatment. Conclusion In patients with complete remission of malignancies, newly developed bilateral hilar and mediastinal lymphadenopathies with or without pulmonary nodules of perilymphatic distribution, in the absence of recurrence at the primary tumor site and extrathoracic metastasis, may suggest a sarcoid-like reaction. Such cases warrant histologic evaluation of the lymph nodes to prevent unnecessary systemic chemotherapy.

We report the patient presented with a left-sided pleural effusion. Pleural fluid analysis revealed lymphocyte-dominant exudates with lower level of adenosine deaminase and negative cytologic malignancy. Thoracoscopic examination and histologic examination revealed metastatic nodules on pleurae, proven to be from the papillary thyroid cancer. There were no other sites of distant metastases. Though papillary thyroid cancer is characterized with slow progression and relatively good prognosis, metastatic pleural effusion as an initial manifestation of undiagnosed papillary thyroid cancer can be considered.

Lymphoma is a common cause of nontraumatic chylothorax. Clinical success rates of thoracic duct embolization are lower in patients with nontraumatic chylothorax compared to patients with traumatic chylothorax. Herein, we report a case of nontraumatic chylothorax and lymphoma in a 77-year-old man managed with thoracic duct embolization. The chest tube drainage decreased but not was sufficient to enable removal of the chest tube. Therefore, a second embolization was performed through a direct puncture of the lymphatic mass in the lung, following which the chyle leakage ceased, and the chest tube was removed. The treatment strategy discussed in this report may be an effective therapeutic option for select patients with nontraumatic chylothorax.

Purpose : The purpose of our study was to assess the usefulness of the Tl-201 SPECT for the detection of the postoperative tumor recurrence on chest wall. Methods: 28 patients including 14 with suspected recurrence of tumor in the chest wall on postoperative chest cr scan, 10 with postoperative pleural effusion which proved benign on radiologic, cytologic and laboratory findings, and 4 with chronic tuberculous empyema as control group were included. All patients underwent SPECT 30 minutes and 4 hours after intravenous injection of 111MBq of Tl-201. Tumor uptake was visually graded by two interpreters and scored as follows : no uptake:0, similar to contralateral lung: 1, higher than contralateral lung but less than heart:2 and similar to heart:3. Results : Markedly increased (grade 3 or 2) Tl-201 uptake was noted in patients with suspected recurrence of tumor in the chest wall (13/14) whereas no (8/10) or minimal (2/10) uptake along the collapsed lung in patients with postoperative benign pleural effusion. In two patients, Tl-201 SPECT revealed additional recurrent tumor mass lesions that were barely perceptible on chest cr scan. Patients with chronic tuberculous empyema showed relatively smoothly marginated increased uptake along the chest wall 4/4), but lesser in degree (grade 1 or 2), when compared to recurrent tumor uptake. Conclusion : Tl-201 lung SPECT seems to be useful to detect postoperative tumor recurrence on chest wall and to differentiate malignant from benign pleural effusion and may provide additional information to the morphologic data obtained by CT.

From 1991 to 1994, We performed 75 cases of pulmonary resection. These were divided into two groups according to the method of bronchial stump closure : 51 cases automatic staplers were a plied in 49 patients (Group 1), 24 patients were closed with manual interrupted suture (Group II). Disease entities of the patients were malignant tumor in 33 patients(Group I: Group II, 22· II, bronchiectasis in 23(18:5), benign tumor in 5(3:2), aspergilloma in 5(2:3), tuberculosis(2:1) in 3, bronchogenic cyst in 2 (0 : 2) and so on. Surgical Procedure% for these Patients were 21 Pneumonectomies(18:3), 13 bilobectomies(11:2), 26 lobectomles (14:12), 11 segmentectomies (6:5) and 4 lobectomy with segmentectomies (4:0). In conclusion, the Amount of tube drainage was smaller and the removal of chest tube after surgery was shorter than manual bronchial closure group by means of statistical significance (p=0.047, p=0.005). Although there were no statistical significance, the duration of air leakage was reduced and incidence of bronchopleural rstula was reduced in the stapler used group compared with manual bronchial closure.

Solitary fibrous tumor is an uncommon submesothelial mesenchymal neoplasm that primarily arises from the pleura. Most solitary fibrous tumors have a benign course, and the single most important predictor of the clinical outcome is the ability to excise the entire lesion. We experienced a case of CSF leakage through a subarachnoid-pleural fistula after resection of a malignant solitary fibrous tumor and the involved rib. We detected CSF leakage via performing CT myelography and we treated this case with hemilaminectomy and dura repair.

Mediastinal lipoblastoma is a rare benign tumor originating from embryonic lipid cells and it almost always occurs during infanthood or early childhood. It is a tumor with a good prognosis despite its potential for local invasion and rapid growth. We report here on a three years old girl who was treated for a benign lipoblastoma in the anterior mediastinum. CT scanning showed a fat containing mass without internal calcification or fluid component, and the mass showed a compressive effect on the adjacent structures. The mass was located between the pericardium and right mediastinal pleura and it was removed completely without complication. Pathologic examination revealed a benign lipoblastoma. The patient showed no evidence of recurrence at the time of the report.
