Abstract: Objective To investigate the clinical features of solitary fibrous tumor (SFT) in the thorax and its optimal surgical approaches. Methods We retrospectively reviewed the clinical records of 16 patients with SFT in the thorax in our hospital between January 2004 and June 2010. There were 8 males and 8 females, with a median age of 49 years (1973 years). Laboratory examination showed normal results. Chest Xray and computed tomographic scan revealed lung tumor in 8 cases, mediastinal mass in 3 cases, fibrous tumor in 2 cases, pleural mass in 2 cases, and retroperitoneal mass in 1 case. Five patients underwent CT guided biopsy or thoracoscopy, and 3 of them were diagnosed to have SFT. There was no clear diagnosis for the remaining 13 cases before operation. None of them had been exposed to asbestos. Symptoms were present in 5 patients. All patients underwent surgical treatment with resection performed through routine thoracotomy in 10 cases and by means of videoassisted thoracoscopy in 6 cases. The tumors originated from the visceral pleura in 12 patients, from parietal pleura in 3 patients (from diaphragmatic pleura in 1, and costal pleura in 2), and from the lung in 1 patient. Results All tumors were totally excised. Immunohistochemical staining showed CD34 was positive in all tumors. There was no postoperative mortality and no major complications. All patients were regularly rechecked and followed up. The followup was ranged from 1 to 72 months, with a median time of 21 months. During the followup, all patients survived and no recurrence was observed by means of chest X radiography or CT. Conclusion SFT tumors in the thorax are rare neoplasms and can have giant diameters. Wide local excision is recommended as the best therapeutic option. The SFT has the possibility of recurrence, and careful longterm clinical followup is required.
Objective To observe the effectiveness of skin graft combined with thorax wire fastening for repairing postoperative coloboma after resection of chest back giant nevus. Methods Between June 2007 and October 2010, 17 cases of chest back giant nevus were treated. There were 7 males and 10 females, aged from 3 years and 6 months to 15 years(mean, 8 years). The size of giant nevus was 20 cm × 12 cm to 60 cm × 50 cm. Two cases of them were ever treated by laser, while the others were never treated. The check before operation showed ulcer of the skin and effusion in 2 cases, hard skin in 3 cases, hair growth in 7 cases, and normal in 5 cases. Five cases had serious itch. After giant nevus was cut off, thorax wire was fastened to reduce the wound area, and then the intermediate spl it thickness skin graft of thigh was used to repair the wound. Comprehensive anti-scar treatment was given postoperatively. Results The wound size was (2 110.74 ± 725.69) cm2 after resection of giant nevus, and was (1 624.94 ± 560.57) cm2 after thorax wire fastening, showing significant difference (t=9.006, P=0.001). All the grafting skin survived; the incision and wound at donor site healed by first intention. The patients were followed up 6 months to 2 years (mean, 13 months). No scar prol iferation or contracture occurred. The skin color and elasticity were similar to the normal skin; the nipple, navel, and other local apparatus were not shifted after operation. Conclusion It can reduce donor site of skin and postoperative scar, and achieve satisfactory appearance to cover the wound by skin graft combined with thorax wire fastening after chest back giant nevus was cut off .
