Obstructing endobronchial malignant fibrous histiocytoma.

A 58-year-old male patient admitted with malignant fibrous histiocytoma of the left mainstem. Rareness and unusual presentation of malignant fibrous histiocytoma and surgical management for lung salvage made its reporting worthwhile. In this localization, prognostic characteristics are better than in the other localizations of lung and body.     

Benign fibrous histiocytoma: a rare endobronchial neoplasm

Fibrous histiocytomas are rarely found within the lung and have presented as a mass within a major airway only twice previously. This is the third reported case of such a tumor visualized roentgenographically in an airway on the frontal chest film of a patient presenting with recurrent pneumonia.     

Retroperitoneal malignant fibrous histiocytoma.

Authors review the case history and follow-up a rare malignant fibrous histiocytoma patient, based on the relevant literary data. The tumor filled the retroperitoneum on the right side, in front of the right kidney. Intravenous urography and computer tomography revealed a 10 x 15 cm sized mass, suspect of being a kidney tumor. Upon surgery, the tumor was found to be a retroperitoneal malignant fibrous histiocytoma. In connection to the case, a brief review is given of the storiform type of malignant fibrous histiocytoma, regarding its etiological, clinical and pathological aspects, the difficulties in diagnosis, as well as the therapeutic possibilities. Authors regard their case worthy of publication because of the retroperitoneal location and significant size of the tumor, and because of the unproven diagnosis prior to surgery. Even after 4 years the patient is symptom- and complaint-free, and CT has revealed no metastases.     

Recurrent facial fibrous histiocytoma.

A case of fibrous histiocytoma required 4 surgical excisions over an 11-year period. The technique of frequent observation and early excision of recurrences is probably the best approach to established histiocytomas. Complete primary excision seems to offer the best chance of definitive cure.     

Renal malignant fibrous histiocytoma.

The clinical, radiographic, and pathologic findings of 2 cases of malignant fibrous histiocytoma (MFH) of the renal capsule are reported and the 17 previous cases in the literature reviewed. Preoperative differentiation from renal adenocarcinoma was precluded by the overlap in clinical, laboratory, and radiologic findings, although MFH usually presented with a normal urine analysis and less parenchymal involvement on imaging studies. Pathologic differential diagnosis and therapeutic approaches are presented.     

软组织恶性纤维组织细胞瘤的治疗(附12例报告)

发生于软组织的恶性纤维组织细胞瘤１２例，平均年龄６１．９岁，平均随访２９个月。本病与发生在骨组织的恶性纤维组织细胞瘤不同，病理学还可分为席纹样－多形性型、粘液样型、巨细胞型、黄色肉芽肿型。本病局部广泛切除可以得到较好的治疗，综合治疗特别放疗及化疗药物的应用，对减少复发，治疗转移有一定的疗效。     

A case of primary malignant fibrous histiocytoma of the lung

A 68-year-old woman presented with a complaint of coughing and chestroentgenography and computed tomography revealed a very large, irregular mass in the left inferior lobe of the lung. The suspected preoperative diagnosis was sarcoma. Therefore, a complete resection of that mass was considered to be difficult. The patient received preoperative chemotherapy including cisplatin with vindesine as employed for non-small cell lung cancer. She demonstrated a clinical response after three cycles of the chemotherapy and underwent surgery successfully. A postoperative diagnosis of MFH was made based on the histology of the tumor, which was pleomorphic with a storiform pattern. The tumor cells showed positive immunostaining for alpha 1-antitrypsin and alpha 1-antichymotrypsin but were negative for SMA and S-100 protein. The patient underwent a further three cycles of postoperative chemotherapy and has remained disease-free for 12 months after tumor resection.     

Malignant fibrous histiocytoma: review and case report.

Malignant fibrous histiocytoma (MFH) is a rare tumour of the spermatic cord. We present the second reported case in Australia and review the literature, discussing the recommended management and prognosis of this condition.     

Malignant fibrous histiocytoma mimicking pulmonary embolism.

A rare case of malignant fibrous histiocytoma occurring in the pulmonary artery is reported. Such primary pulmonary artery sarcomas may have the diagnosis suggested by angiography or echocardiography; radiographically and in perfusion-ventilation scanning their usual unilateral origin (with later spread) and the persistence of the perfusion defect are among the features normally distinguishing them from thromboembolism.     

Malignant fibrous histiocytoma of spermatic cord.

Malignant fibrous histiocytomas are very rare, particularly those related to urogenital organs. We report herein the third known case of this entity involving the spermatic cord. Summary of the previously reported 2 cases is given with recent follow-up. Prognosis is poor.     

Malignant fibrous histiocytoma of the mediastinum and lung: a report of three cases

One case of primary malignant fibrous histiocytoma of the lung and two cases of that tumor in the mediastinum are reported. Primary malignant fibrous histiocytoma is rare in those areas, appearing more commonly in deep fascia and skeletal muscles of the extremities and torso and in the retroperitoneum. Most of the tumors contain both fibroblast-like and histiocyte-like cells; some contain pleomorphic giant cells and inflammatory cells. They are often confused with other sarcomas, and their true biologic potential is not clearly defined. Radiation appears to be a very useful adjunct to surgical therapy and was used in the cases reported here.     

Primary malignant fibrous histiocytoma of the mediastinum.

A malignant fibrous histiocytoma of the mediastinum was successfully treated by surgery and radiotherapy. Magnetic resonance imaging was able to show the site of invasion, the two different components of the tumour, and the blood supply.
