电视胸腔镜手术治疗胸膜孤立性纤维瘤的临床分析

目的探讨电视胸腔镜手术（VATS）治疗胸膜孤立性纤维瘤（SFTP）的价值,总结微刨治疗经验。方法1999年2月至2010年10月VATS治疗SFFP患者19例,其中全胸腔镜手术14例,胸腔镜辅助小切口（6～8cm）手术3例,胸腔镜联合后外侧大切口（15cm）手术2例。结果全组均完整切除肿瘤,手术顺利,无并发症及围手术期死亡。术中证实13例肿瘤起源于脏层胸膜有蒂,5例起源于壁层胸膜无蒂宽基底,1例起源于纵隔胸膜有蒂。主要诊断依据免疫组化分析,19例患者的Vimentin和CD34均阳性表达;病理诊断良性17例,恶性2例。平均住院时间6d（4-11d）。术后平均随访51个月,无复发和转移。结论VATS创伤小,可作为治疗SFTP的首选方法,值得推荐。

Immunohistochemistry and surgical approaches in solitary fibrous tumor of the pleura

Solitary fibrous tumor of the pleura (SFTP) is a rare, benign, slow-growing neoplasm that arises from the submesothelial cells of the pleura. Usually, resection of the tumor and adjacent structures are sufficient for resolution. Nowadays, videothoracoscopy (VTC) allows adequate access for the surgical treatment of these tumors. CD34 antigen positivity is a differential feature with mesothelioma. We present our experience with 15 patients with SFTP (nine women and six men) who underwent surgical resection in the last 12 years (10 thoracotomies, one sternotomy and four VTC). Only four patients were symptomatic at diagnosis. In our opinion, VTC is a less invasive diagnostic and therapeutic approach than thoracotomy that provides an adequate approach for the resection of SFTP in selected patients. Because of the malignant potential of this tumor, long-term follow-up is mandatory.     

Giant solitary fibrous tumor of the pleura

Primitive neoplasms of the pleura are uncommon. Solitary fibrous tumor of the pleura (SFTP) is a benign variety of primitive pleural tumor, which is usually asymptomatic and discovered as an incidental finding. However, these tumors can sometimes become locally aggressive and can even be life-threatening. The treatment of choice is surgical resection. We report a case of SFTP in a 78-year-old woman with no relevant history, who presented with marked respiratory insufficiency and who required extended posterolateral thoracotomy to achieve complete resection of an SFTP weighing 2 kg.     

Giant solitary fibrous tumor of the pleura

Fibrous tumors of the pleura are rare, accounting for <5% of all pleural neoplasms. Although over 80% of pleural fibrous tumors have a benign course, local recurrence postsurgery and occasional malignant transformation have been reported; complete excision of the tumor together with postsurgery follow-up of all patients is therefore recommended. We report on a solitary fibrous tumor of the pleura measuring 30?cm and weighing 3560?g.     

Primary solitary fibrous tumor (SFT) in the retroperitoneum

BACKGROUND: Solitary fibrous tumor (SFT) is an infrequent but distinct neoplasm, which generally arises from submesothelial connective tissue in the pleura. SFT is rarely recognized in extrathoracic sites, and histologically identical conditions have also been reported in the retroperitoneum, although their pathophysiology has not been extensively investigated. METHODS: We present four cases of primary SFT in the retroperitoneum, and review 37 similar cases in the previous literature. RESULTS: About 40% of patients were asymptomatic, and 19.2% and 15.4% presented with an abdominal mass and urinary symptoms, respectively. The tumor size ranged between 2 and 26 (mean 9.1) cm. Sixty-three percent of tumors showed nonspecific development with haphazard distribution of bland short spindle or polygonal cells with or without collagenous bundles and stromal hyalinization. In 22.0%, hemangiopericytomatous appearance was seen. About 15% of cases showed histologically malignant characteristics. The tumor cells were immunoreactive for vimentin in all cases, CD34 in 91% and Bcl-2 in 86%. All tumors were excised, and in 85.4% of cases, tumors did not recur postoperatively for 6 to 48 months. No significant difference was found between the recurrence rate of histologically benign and malignant cases. Cases positive for both CD34 and Bcl-2 had no recurrence. CONCLUSIONS: The identification of SFT in the retroperitoneum is of importance because histopathological indicators of malignancy are not necessarily associated with clinical malignant potential in many cases of retroperitoneal SFT. Retroperitoneal SFT showing typical pathological features with expression of CD34 and Bcl-2 is associated with a favorable outcome following excision.     

Huge malignant solitary fibrous tumor of the pleura

Introduction  

Solitary fibrous pleural tumors are rare mesenchymal tumors that can be mistaken for mesothelioma. A positive staining of vimentin, negative staining of cytoplasmic keratin, and expression of the CD34 antigen can confirm their diagnosis. These tumors should be surgically excised although they are benign because they have malignant potential and tendency for recurrence.     

Malignant solitary fibrous tumor in the pleura.

We present a case of malignant solitary fibrous tumor of the pleura in an asymptomatic 75-year-old man. A needle biopsy specimen revealed a solitary fibrous tumor of the pleura with suspected. The tumor was resected and the final diagnosis was a malignant solitary fibrous tumor. At one-and-a-half years later, the patient has no clinical or radiological evidence of recurrence. The propriety of a needle biopsy for preoperative diagnosis is discussed.     

A locally aggressive solitary fibrous tumor of the leg: Case report and literature review

INTRODUCTIONThe solitary fibrous tumor (SFT) is a rare soft tissue tumor with a substantially benign clinical behavior. However, malignant neoplasms with local recurrence or distant metastases have been reported.PRESENTATION OF THE CASEThe authors present a case of an aggressive SFT of the leg, in a 55 years old Caucasian man. Radiological, histological and molecular findings are reported. The differential diagnosis, therapy and outcome of this rare tumor are also discussed.DISCUSSIONAn extensive review of literature showed SFT's clinical behavior as substantially benign, anyway aggressive or malignant neoplasms have been described. The potential risk of local recurrence and distant metastasis thus suggests wide surgical resection and careful long-term follow-up. Differential diagnosis may be quite laborious as SFT can mimic a variety of benign and malignant mesenchymal tumors; immunohistochemical analysis for CD34, CD99, vimentin and bcl-2 is then mandatory.CONCLUSIONOur clinical experience confirmed that SFT may have an aggressive behavior, however, conservative surgical treatment may be successful in the long term.     

A resected case of solitary fibrous tumor of the pleura

A 45-year-old female with solitary fibrous tumor (SFT) of the pleura was reported. Chest X-ray and CT scan on admission showed a large tumor in the right thoracic cavity. A preoperative needle biopsy was performed. The microscopic appearance of biopsied specimen revealed many spindle cells. And an immunohistochemical study was positive for CD 34 and negative for keratin, epithelial membrane antigen, alpha-smooth muscle actin, S-100 protein. So SFT was strongly suspected and an operation was performed. A tumor arised from the visceral pleura of right middle lobe and was pedunculated. The tumor was 13 x 10 x 7.5 cm in size. An immunohistochemical study of the tumor was positive for CD 34, and negative for SMA, ki-67. From these immunohistochemical stainings and microscopic findings, the tumor was diagnosed as SFT. An immunohistochemical study of the tumor seems to be very useful for the diagnosis of SFT.     

Contralateral recurrence of a malignant solitary fibrous tumor of the pleura

We present an unusual case of a contralateral recurrence of malignant solitary fibrous tumor of the pleura (SFTP) nine years after a complete resection. Recurrence of malignant SFTP has already been described, but is usually localized. In our case the patient underwent surgical resection for a malignant SFTP of the left upper lobe in 2000. Nine years later computed tomography (CT)-scans showed lesions that were suspicious of tumor recurrence in the right lung. Thoracoscopy, wedge-resections and pathological findings revealed four nodules of a malignant SFTP of the right middle and lower lobe, histopathologically identical to the tumor, which had been resected nine years ago. A coincidental mucinous bronchioloalveolar carcinoma of the left lower lobe was resected by thoracotomy. To our knowledge this is the first report of contralateral recurrence of a malignant SFTP years after complete resection in the literature. The possibility of a new primary tumor on the right with local metastasis could not be excluded in the clinical and histopathological examinations. Therefore, contralateral recurrence of malignant SFTP should be considered in the postoperative follow-up even years after complete resection.
