RESUMEN
A 28-year-old female patient presented with back pain, dyspnea and coughing. Chest radiograph showed a mass in the middle zone of the right hemithorax. CT confirmed the mass was confined to the 5th rib. During the exploratory thoracotomy, a smooth, firm mass measuring 7 x 9 x 5 cm was found to have destroyed the middle and posterior parts of the 5th rib. Together with the adjacent intercostal muscles, the 5th rib was excised en-block. Postoperative pathology was cavernous haemangioma. Cavernous haemangioma of the rib is very rare, and very few cases have been reported in the literature.

AIM: Intraoperative frozen section examination (FSE) is an important tool for determining how extensive a surgical procedure needs to be. In this study we reviewed the indications for FSE, the correlation between FSE and postoperative histopathology, and the contribution of intraoperative FSE in determining the extent of the surgical procedure. METHODS: A total of 744 FSE performed in 721 patients between January 1995 and January 2004 were reviewed retrospectively. The FSE were divided into 7 groups according to the indications of the request for frozen section. False positivity and false negativity were evaluated. RESULTS: The indications for FSE included intraoperative diagnosis of pulmonary masses (311, 41.8%), determination of N2 status with mediastinoscopy and mediastinotomy (153, 20.6%), staging of pulmonary carcinomas during the operation (86, 11.6%), assessment of the margin of bronchial surgical resection following pulmonary resection (54, 7.2%), presence of solitary pulmonary nodules (75, 10.1%), presence of mediastinal masses (39, 5.2%), and pleural thickening (26, 3.5%). When compared to postoperative paraffin sections, FSE was found to have a 1.9% (8) rate of false negatives and a 0.2% (1) rate of false positives (P < 0.001). CONCLUSIONS: Intraoperative FSE in thoracic surgery is a rather reliable method. When FSE indicates malignancy, it is a valuable guide in directing the extent of the ongoing surgical procedure. However, when FSE indicates a benign lesion, surgeons should interpret this in the light of the patient's clinical and radiological features and the lesion's macroscopic nature when deciding how extensive an operation needs to be.

Primary pulmonary lymphomas (PPL) only constitute 4% of extra-nodal, non-Hodgkin lymphomas (NHL), less than 1% of NHL in general, and between 0.5% and 1% of malignant pulmonary neoplasms. Fifty-eight to 87% of cases of this extremely uncommon disease are low-grade B-cell lymphomas and 11%-19% are high-grade or large B-cell lymphomas. The prognosis for.high-grade or large B-cell lymphomas is worse than for low-grade lymphomas; respiratory and general symptoms are usually present. However asthmatic symptoms are not often found in their clinic. We report the case of a 49-year old woman with resistant asthma clinic in the form of wheezing, dyspnea and non-productive painless cough; associated with an irregular lobulated mass with air bronchograms in the lower lobe of the right lung. Histological diagnosis showed a pattern of high-grade B-cell lymphoma and all asthmatic symptoms disappeared following gross total resection of this lesion.

A cystic lesion of the liver extending into the inferior vena cava was discovered in a 33-year old female patient suffering from dyspnea, pain and swelling in the legs. Plain chest X-ray was normal. CT and MRI of the thorax showed a cystic lesion within the right pulmonary artery. The liver lesion was treated by a partial cystectomy and omentoplasty, inferior vena cava and bile ducts repair. Through a right thoracotomy, a hydatid cyst was found in the pulmonary artery and enucleated. Although very rare, pulmonary artery hydatidosis may be the cause of an unexplained dyspnea in patients with hydatidosis of the liver.

As the liver and the lungs are the most common sites for hydatid cysts, a primary mediastinal involvement is quite rare. The symptoms related to primary mediastinal hydatid cysts usually depend on the size, location and compression to nearby structures. Presenting a 51-year-old male patient with the symptoms of Horner's Syndrome, we draw attention to a rare complication of a giant primary mediastinal hydatid cyst and its challenging management.

Attempts for right and left subclavian vein catheterizations were unsuccessful in a patient followed for pre-eclampsia. Meanwhile, the patient developed chest pain and dyspnea. Chest radiography revealed mediastinal widening. Later, mediastinal haematoma was diagnosed by thoracic computed tomography. At 28 days follow-up, the mediastinal haematoma was resorbed. A review of literature revealed very few cases of mediastinal haematoma secondary to subclavian vein catheterization. In all these cases the haematoma was resorbed, usually within one week. Mediastinal haematoma is a rare complication and its resolution after several weeks adds to its rarity.

PURPOSE: Majority of tracheobronchial foreign body aspirations occur in paediatric age group and may constitute a life hazard. We examined the relationship between the time of admittance and complications in children with tracheobronchial foreign body aspiration. MATERIAL AND METHODS: Sex, age, time of admittance, presenting symptoms, radiological findings, and the nature of the foreign body were reviewed retrospectively in patients aged 16 and under follow-up for tracheobronchial foreign body aspiration between January 1990 and January 2005. Cases were randomly assigned into 6 groups based on admittance times. RESULTS: Within 15-year period, 263 children under the age of 16 were followed-up for tracheobronchial aspiration of foreign body. The most commonly aspirated foreign bodies included sunflower seed, peanut, hazelnut, walnut. While the pathology could be detected radiographically in 80.3% (n : 211) of the cases, in 19.7% (n : 52) radiology was normal. All cases had rigid bronchoscopy under general anaesthesia. In 220 cases foreign body was detected and could successfully be removed in 209 cases. The remaining 11 cases required bronchotomy or pneumotomy to remove the foreign body. Among 679 cases operated for bronchiectasis during the same period, 22 cases (3.2%) had foreign body as the aetiology. No complications were observed when the patients presented to the hospital within the first 24 hours after the aspiration while fever, purulent sputum, haemoptysis and bronchiectasis were noted in those presented later. Most of the complications were medically treated. CONCLUSION: Paying medical attention within the first 24 hours after the aspiration of foreign bodies is critical in order to accomplish a complication-free course. Organic foreign bodies and retention period of 30 days and over, constitute major risk factors in the development of bronchiectasis. It is advisable to perform bronchoscopy in the early stages of all suspected cases to avoid serious complications such as bronchiectasis.

OBJECTIVE: Re-mediastinoscopy can be a difficult procedure due to fibrosis in the mediastinum. We have investigated the effect of an anti-adhesive barrier agent "hylan B gel" on the formation of adhesions after dissection in the superior mediastinum in a rat model. METHODS: The study was conducted in 70 male Sprague-Dawley rats weighing 300 g. The strap muscles were divided by a midline cervical incision. The anterior and lateral aspects of the trachea were dissected to the level of the carina. Hylan B gel (Sepragel Sinus, Genzyme Company, Redgefield, NJ, USA) was used to create an anti-adhesive barrier. The rats who were subjected to surgery were sacrificed on postoperative days 14 and 28. All rats were previously divided into 5 groups: Sham group (n = 10); Group 1 (n = 15) surgery alone, sacrificed on day 14; Group 2 (n = 15) surgery and Sepragel, sacrificed on day 14; Group 3 (n = 15) surgery alone, sacrificed on day 28; Group 4 (n = 15) surgery and Sepragel, sacrificed on day 28. Histopathological analysis was performed to study the effect of the anti-adhesive agent. Scores were calculated based on collagen fibrosis, fibroblasts, granulation tissue, muscle alterations/inflammation, histiocytes, mononuclear giant cells, inflammation and vascular proliferation. RESULTS: Collagen fibrosis and fibroblast scores, which represent adhesions, were significantly higher in Groups 1, 2, 3, 4 than in the Sham group ( P < 0.01). The degree of adhesions on day 14 was found to be higher in Group 1 compared to Group 2 ( P < 0.01). Adhesions on day 28 were higher in Group 3 compared to Group 4 ( P < 0.01). There were no differences between groups with regard to foreign body reactions ( P > 0.05). CONCLUSION: Adhesions causing technical difficulty during re-mediastinoscopy can be reduced by the application of anti-adhesive agents during the primary procedure.

BACKGROUND: Completion pneumonectomy performed for benign causes is associated with a high morbidity and mortality. We analyzed the patients who underwent completion pneumonectomy procedure for bronchiectasis, which constitutes a specific benign condition, together with the indications for surgery, the difficulties encountered during operations and the postoperative results. METHODS: Records of all patients who underwent completion pneumonectomy for the diagnosis of brochiectasis between January 1991 and April 2006 at the thoracic surgery clinic of a training and research hospital specializing in chest diseases and chest surgery were retrospectively evaluated. The age and the gender of the patients, etiologic factors, symptoms, characteristics of the first operation, the time between the first operation and completion pneumonectomy, and postoperative follow-up are examined. RESULTS: During the evaluation period of more than 15 years, 23 patients underwent completion pneumonectomy. The median age of these 23 patients was 28 (range: 9 - 53); 17 of the patients were male and 6 were female. The most common indication for surgery was recurrent lung infections (n = 15). The most common symptoms were cough (n = 21), expectoration (n = 19), and hemoptysis (n = 15). The mean time between the first operation and the completion pneumonectomy was 4.9 years (range: 5 months - 11 years). Left completion pneumonectomy was performed in 14 and right completion pneumonectomy was performed in 9 cases. The mean duration of hospital stay was 16.7 days (range: 12 - 42 days). The course after surgery was uneventful in all patients. The mortality rate was 0 % and morbidity was 43.5 %. CONCLUSION: Although completion pneumonectomy for benign causes is a high risk procedure, it can be performed in selected patients with an acceptable morbidity and mortality after an effective preoperative medical therapy for inflammation of the lungs and with careful dissection at the operation.
