孤立性纤维性肿瘤的诊断及外科治疗

目的探讨孤立性纤维性肿瘤的诊断及外科治疗方法。方法回顾我院10年来经手术切除并行病理检查确诊为孤立性纤维性肿瘤的病例资料,就其诊断和外科治疗方法进行总结与分析。结果共16例次患者,肿瘤分别位于胸腔、腹股沟、后腹膜、外阴、颈部、下肢等部位,无明显特异的临床症状。所有病例均行手术完全切除肿瘤,术后经病理学检查和免疫组化染色检查确诊。对患者定期随访,其中2例分别于术后5年和7年肿瘤复发,2例分别随访3年和5年后失访,2例患者分别于随访的第9个月和16个月因全身多发转移死亡,其余患者仍在随访中。结论孤立性纤维性肿瘤大多数病例表现为局部缓慢生长的无痛性肿块,无明显的临床症状,术前诊断较困难,目前仅能依靠术后免疫组化检查确诊,手术切除是最佳的治疗方法。

Intrapulmonary solitary fibrous tumor with bronchial involvement: a rare case report in a child

Intrapulmonary solitary fibrous tumor is a very rare neoplasm. Our review of the English literature suggests that it has not previously been reported in children younger than 10 years. Herein, the occurrence of such a rare lesion invading the tracheobronchial tree is reported in a 7-year-old boy.     

A recurrent solitary fibrous tumor of the thigh with malignant transformation: A case report

IntroductionWe describe an unusual case of a uniformly high-grade malignant solitary fibrous tumor (SFT) of the thigh with recurrence after wide resection in a 31-year-old man.Presentation of caseOur current case showed a long-term benign course before the operation, although the subcutaneous tumor was larger than 10 cm at presentation. The SFT was diagnosed by needle biopsy, and wide resection was performed. Histological findings showed proliferation of capillaries surrounded by masses of spindle-shaped cells without any cytologic atypia, and the percentage of MIB-1-positive nuclei was 2.1%. However, a rapidly enlarging recurrent tumor was observed 11 months after the operation. A second wide resection for the recurrent tumor was performed. Histologically, the tumor cells uniformly displayed significant cytologic atypia and pleomorphism, and had 40–50 mitoses per 10 high-power fields. The proportion of MIB-1-positive nuclei was 48%. Consequently, the tumor was diagnosed as a SFT with malignant transformation.DiscussionThe malignant transformation described in past studies showed high-grade areas within benign, low-grade, or intermediate-grade SFTs. Therefore, in contrast to our case, uniformly high-grade malignant histological findings at recurrence were not described.ConclusionEven if a tumor is non-malignant during the clinical course, as confirmed by tissue biopsy, the possibility of tumor progression to high-grade sarcoma at recurrence should be considered, and the treatment strategy should be determined carefully.     

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.     

Malignant solitary fibrous tumor of the lumbar spinal root mimicking schwannoma: a case report

Background contextMalignant solitary fibrous tumors (SFTs) arising from the spinal cord are extremely rare and poorly understood mesenchymal neoplasms. To date, only one malignant SFT located in the spinal canal of the sacrum has been described, but none arising from the lumbar nerve root have been reported. Although most SFTs with benign histological features can be treated by complete surgical excision alone, malignant SFTs may require adjuvant therapy. However, systemic chemotherapy and radiotherapy have not been shown effective in patients with malignant SFTs.PurposeTo describe a patient with a malignant SFT arising from the lumbar nerve root.Study designA case report and review of literature.MethodsWe describe the clinical course of the patient and the radiological and pathological findings of the tumor. The effect of systemic chemotherapy was evaluated and the relevant literature was reviewed. This work has no disclosure of funding and was approved by the Institutional Review Board of Gifu University.ResultsThe tumor had been resected previously at another hospital, but it recurred and showed multiple metastatic lesions on both lungs within 3 months. Although the patient received systemic chemotherapy, both primary and metastatic lesions were found to be stable disease according to Response Evaluation Criteria in Solid Tumors. The patient died due to cachexia 6 months after her first visit.ConclusionThis patient presented with a highly unusual tumor. Even if a tumor is a dumbbell-shaped mass, similar to a neural tumor, SFT should be considered in the differential diagnosis.     

Mediastinal solitary fibrous tumor with right diaphragm invasion: Report of a case

Mediastinal solitary fibrous tumors (SFTs) are rarely found in adults and there are few reports describing primary mediastinal SFT invading the diaphragm. We report the case of a 47-year-old woman with a large right inferior mediastinal SFT. Magnetic resonance imaging showed the tumor invading the right lower lobe of the lung and the right hemidiaphragm, with displacement of the inferior vena cava (IVC) and right lobe of the liver. Angiogram showed IVC stenosis. To our knowledge, this is the first report of complete resection of the tumor combined with right lower lobectomy of the lung and partial resection and reconstruction of the right diaphragm with a Dacron flap.
