A 70-year-old female who was diagnosed as myxoid chondrosarcoma by fine needle aspiration of a pleural mass is described. She presented with left chest discomfort of 4 months' duration and aggravating dyspnea and chest pain for 2 months. Chest X-ray and CT scan revealed a large lobulated low density mass invading chest wall at the left pleural cavity and massive pleural fluid. Fine needle aspiration was done under the impression of mesothelioma or metastatic cancer. The aspirates from the mass were very cellular and composed of isolated or clustered forms of large plump cells. Abundant cytoplasm was blulsh opaque and the margin was rounded in the isolated cells, whereas clustered cells show ill-defined ceil borders and aggregating tendency. The nuclei were eccentric, round to ovoid, and had fine chromatin pattern and multiple small nucleoli. Cellular pleomorphism or mitotic figure was not definite. These findings were consistent with cytologic features of chondrosarcoma. Final diagnosis was confirmed as myxoid chondrosarcoma by mediastinoscopic biopsy and the tumor showed strong positivity for S-100 protein.

Pulmonary amyloid deposition generally occurs with concurrent primary systemic amyloidosis. Localized forms of pulmonary amyloidosis are rare and appear most frequently as an incidental finding on chest radiographs. We present a case of nodular pulmonary amyloid tumor suggested by fine needle aspiration cytology(FNAC) and confirmed by histology examination with the polarizing light microscopy. A 41-year-old woman presented with ill-defined nodules. In the middle and lower lobes of both lungs. FNAC of the nodules revealed waxy, acellular amorphous fragments. Thoracotomy for diagnosis may be avoided by FNAC diagnosis of this unusual lesion.

Background: We wanted to examine the clinical characteristics of adult patients with tracheobronchial foreign bodies (FBs) according to the risk of aspiration and the outcomes of intervention with using a fiberoptic bronchoscope. Methods: From December 1994 through December 2004 at Kyung Hee Medical Center, we retrospectively analyzed the medical records of 29 adult patients with FBs that were identified by using a fiberoptic bronchoscope. Results: 14 patients were not at risk of aspiration, whereas 15 had cerebrovascular diseases and they were at a high risk of aspiration. No history suggestive of FB aspiration was noted in 7 (24.1%) patients. Respiratory symptom(s) were noted in 22 patients, and these symptoms were cough (62.0%), dyspnea (44.8%), fever (20.7%), wheezing (13.8%), chest pain (10.3%) and hemoptysis (0.4%). Only 60% of those patients at a high risk of aspiration had symptom(s) (92.8% of those patients without a risk of aspiration had symptoms, p=0.005). Those patients at risk for aspiration had a longer duration of symptoms (median: 4 days vs. 2 days for those patients not at risk for aspiration, p=0.007) before diagnosis. Acute respiratory symptom(s) within 3 days after aspiration were more frequent in the patients without a risk of aspiration (9 vs. 4, respectively p=0.048). Chest x-ray revealed radiological abnormalities in 23 patients, and these were opacities suspicious of FB (n=11), pneumonia (n=8), air trapping (n=5) and atelectasis (n=3). There were no differences in radiological findings according to the risk of aspiration. FB aspiration developed most commonly during medical procedures (57.1% for the patients at risk) and during eating (35.7% for the patients without risk). The most common FB materials were teeth (n = 11). Alligator jaw biopsy forceps (n = 23) was the most commonly used equipment. All of the FBs were removed without significant complications. Conclusion: This study underlines that a tracheobronchial FB in the patients who are at a high risk of aspiration are more likely to overlooked because of the more gradual onset of symptoms and the symptoms develop iatrogenically in many cases.

Cervical subcutaneous emphysema usually occurs as a result of surgery or trauma. However, when it occurs spontaneously, the patient may Present with clinically impressive and dramatic features. Spontaneous subcutaneous cervical emphysema is very rare. A 20-month-old boy diagnosed bronchial asthma had been admitted and all symptoms has improved On 5th hospital admission day, sudden subcutaneous crepitation of cervical, chest and axillary area had developed, and roentgenograms of chest and neck revealed subcutaneous cervical emphysema. He was treated needle aspiration. and recovered rapidly.

A 42-year old male was seen with symptoms of dysphagia, chest pain and dyspnea of 9 months duration. A benign tumor of the posterior mediastinum was diagnosed from x-ray studies and a transthoracic needle aspiration biopsy which was inconclusive. A left thoracotomy revealed a huge mass occupying the retrocardiac space and the contra-lateral mediastinum. It was resected by blunt dissection and, during this process, a 3.0 cm laceration was created in the esophageal wall. This was repaired with Tevdec sutures and staplers and was reinforced with an intercostal muscle flap to prevent leakage. The postoperative course was entirely uneventful.

An unusual case of primary leiomyosarcoma at the left lower posterior chest wall with metastasis to the right lung parenchyme is presented. The patient was a 43-year-old man who was asymptomatic but a slow growing hard mass was noted at the left lower posterior chest wall. The chest computed tomography showed a tumor at the left lower posterior chest wall with multiple metastasis to the right lung. The left lower posterior chest wall mass was examined by percutaneous needle aspiration and it was revealed as rhabdomyosarcoma histologically. En bloc resection to the left lower posterior chest wall tumor and metastasectomy to the multiple nodules in the right lung were done and pathological examination finally revealed primary leiomyosarcoma at the left lower posterior chest wall with multiple metastasis to the right lung. Chemotherapy was scheduled as adjunctive measure.

The practice of oral surgery or other dentistry possesses the danger of causing the loss of foreign bodies used within the oral cavity. If such foreign bodies would be lost, they could enter the viscera through the esophagus or tracheobroncheal tree. Ingestion is four times as frequent as aspiration and 80% to 90% of ingested foreign bodies will pass through the body spontaneously. Once the aspiration or ingestion of foreign bodies is happened, a dental procedure should be discontinued immediately. If symptoms of respiratory distress, including coughing, wheezing, or stridor, are present, a patent airway should be maintained, oxygen administered, and ventilation supported if necessary. The PA chest radiograph will identify the objects in the lung, esophagus, or stomach. Ingested gastrointestinal foreign bodies may be managed by observation, endoscopy, and or surgical intervention and aspirated tracheobroncheal foreign bodies may be managed by bronchoscopy, and or surgical intervention. This case report describes the management of ingested or aspirated foreign bodies happened to the three patients during intraoral treatment. we recommend that the preventive method of ingestion or aspiration of the dental foreign bodies should be performed prior to intraoral treatment and the immedieate measures should be carried out after ingestion or asipiration of it.

Synovial sarcoma us a rare malignant neoplasm of the soft tissue arising in the lower extremity, inguinal area, and upper arm. The majority occurs in patients between the age of 15 and 40 years. The histologic diagnosis is based on the classical biphasic type with the distinct epithelial and spindle cell components. We have recently encountered a case of metastatic synovial sarcoma of the lung diagnosed by fine needle aspiration cytology. A 34-year-old man was admitted because of a palpable mass on the antero-lateral side of the right tibia for 3 years. On admission, a well demarcated metastatic pulmonary nodule, measuring 5 cm in diameter, was also identified in the simple chest X-ray. Resection of the lower leg mass revealed typical histologic features of biphasic synovial sarcoma. Aspiration cytology of the pulmonary nodule revealed numerous clusters of spindle cells admixed with groups of epithelial cells. The epithelial cells had moderate-sized, round to oval shaped, and hyperchromatic nuclei. The cytoplasm was clear, but not distinctive. Interspersed tell elements were fibroblast-like spindle cells having elongated hyperchromatic nuclei.

Proliferative fasciitis is a benign pseudosarcomatous mesenchymal lesion occurring in the subcutis. The lesion occurs clinically as a tumorous mass that develops within a rather short time in elderly patients. We recently experiecened a case of fine needle aspiration cytology of proliferative fasciitis in the left anterior chest wall of a 72 year-old male patient. The smear revealed two types of cells. One was the large and mostly oval cell with one or two nuclei lying at the periphery of the cell body and abundant basophilic cytoplasm like the ganglion cell. The nuclei were round to oval, had vesicular chromatin and contained prominent nucleoli. The other was the spindle shaped fibroblast with an oval nucleus. The differential diagnosis includes a true tumor such as ganglioneuroma, rhabdomyosarcoma, and liposarcoma and therefore fine needle aspiration cytology is very much indicated in order to exclude these possibilities.
