Malignant fibrous histiocytoma is the most common soft tissue sarcoma of late adult life. The tumor occurs principally in one of the extremities or in the abdominal cavity or retroperitoneum, but very rarely in the heart. We report a case of M.F.H. that arose from the posterior wall of the left atrium. A 50 years old woman was presented with signs and symptoms of severe congestive heart failure. On 2-D echocardiographic exam, a huge mass was found in the left atrium. The mass was excised under open heart surgery. Histologic examination revealed that the tumor was actually a malignant fibrous histiocytoma.

Solitary fibrous tumors (SFT) are rare mesenchymal tumors that most commonly develop in the pleura; they rarely involve the diaphragm. MRI has not been widely used to evaluate SFTs of the thoracic cavity, though it may be highly useful in assessing local invasion, predicting malignant potential, and helping in the differential diagnosis. However, MRI findings of malignant SFTs of the diaphragmatic pleura have been described in only two cases. We report a rare case of a malignant solitary fibrous tumor of the diaphragmatic pleura in an 82-year-old man. We describe the clinical and characteristic imaging features, including computed tomography, conventional MRI, and diffusion-weighted imaging. Contrast-enhanced MRI is more accurate than is CT in identifying the origin of SFTs, predicting whether they ae benign or malignant, and assessing local invasion. This imaging modality proved helpful in deciding on the treatment strategy for these rare tumors.

Purpose: Malignant changes of Marjolin's ulcer arising from chronic burn scar are rare. The majority of them are squamous cell carcinoma and basal cell carcinoma. Malignant fibrous histiocytoma is a deep seated pleomorphic sarcoma, which occurs principally as a mass of the extremities, abdominal cavity, or retroperitoneum in adults. Methods: We report a 58-year-old male patient who was admitted due to $3.5{\times}5cm$ chronic ulceration of anterior chest wall on the center of old burn scar. His scar had been occurred by boiling oil and treated with conservative treatment 45 years ago. Preoperative punch biopsy showed suspicious malignant changes and contrast enhanced chest CT showed well-defined, irregular shape enhancing lesion on anterior chest wall without intrathoracic metastasis. Results: The tumor was widely excised and defect was covered with skin graft without infection, necrosis and any other complication. The pathologic findings are compatible with malignant fibrous histiocytoma(storiform - pleomorphic type). The patient underwent 3 cycles of chemotheraphy. Although distant metastasis to the lung developed 6 months later and the patient died 9 month later, there was no local reoccurrence. Conclusion: Aggressive and early excision is needed because malignant fibrous histiocytoma has characteristics of high malignancy with a propensity for early and distant spread. Furthermore, the patient's education about disease entity and postoperative regular follow-up for local recurrence or metastasis is very important. To prevent malignancy from secondly healing burn scar, early skin graft is recommended for patients with deep second degree burn.

Malignant fibrous histiocytoma(MFH) is the malignant part of mesenchymal cell-originated tumor, which is supposed that the tumor is presented various histologic features consisted of fibrosarcomatic and histiocytic portions. When the tumor is arisen in the head and neck region, the most affected sites are the nasal cavity and paranasal sinuses, and secondly the maxillary alveolar bone is occasionally influenced. Therefore, MFH can readily involve the adjacent alveolar bone. The treatment of MFH in the head and neck is various, that is, the involved sites and the differentiation of tumor must be considered when the tumor is treated. The treatment protocols are subjected to general ones of soft tissue sarcoma, and simple or combination therapy is used in the surgery, chemotherapy and radiation therapy. So, we report a clinical case of chemotherapy involving intraarterial chemotherapy, and surgery of malignant fibrous histiocytoma(MFH) in the maxilla, with review of the literature.

1. 연부 조직과 골 조직사이에서의 악성 섬유성 조직구종의 근본적인 조직학적 차이는 없었다. 2. 악성 섬유성 조직구종은 조직학적 소견이 다양하므로, 확진을 위해서는 다른 종양을 반드시 배제하여야한다. 3. 재발시 다른 형태의 조직 소견을 보여줄 수 있기 때문에 정확한 진단을 위해 환자의 과거력 및 과 거의 조직학적 검토가 필수적이라 사료된다.

Primary sarcomas of the lung are rare malignant neoplasms which have usually been classified as fibrosarcomas or leiomyosarcomas. Only 10 cases of primary malignant fibrous histiocytoma [MFH] of the lung have previously been reported in the literatures. The histomorphology of the MFH is marked by their extensive cellular variability, nuclear atypia, abnormal mitotic figures and storiform arrangement of the cells. Recently, we experienced a case of MFH, arising in the parenchyme of lung in 66-year-old male patient, and treated with surgical intervention. So we firstly reported it with review of literatures.

Malignant fibrous histiocytoma is one of the most common soft tissue sarcomas in late adult life. but its incidence in oral and maxillofacial region is extremely rare. We report a case of malignant fibrous histiocytoma which occurred in the infratemporal fossa. Conventional radiograph of this case showed an ill-defined radiolucent lesion in the alveolar bone of the right maxillary first molar area. the lateral wall of the maxillary sinus. and the ascending ramus of mandible. MRI demonstrated a well defined mass of intermediate signal intensitiy in Tl weighted images but T2 weighted images showed two distinctive regions of different characteristics. Upper portion of the lesion was of hyperintense signal but (at) lower portion, the signal intensity decreased clearly, which might mean that this lesion(mass) is composed of two different subtypes though it couldn't be confirmed by histopathological examination. Biopsy was taken the lesion as only in the soft tissue of the maxillary posterior alveolar region and confirmed the storiform-pleomorphic type of malignant fibrous histiocytoma. Histopathological subtype was well consistent with the relatively aggressive imaging findings of that region. We expect more detailed analysis of the nature of malignant fibrous histiocytoma with improvement of the imaging modality and the identification of the relationship between diagnostic imaging and histopathologic findings.

Introduction: Fibrous-osseous lesions of the jaws are difficult to diagnose precisely until excised biopsy results are found, so they might be confused with malignant lesions. This clinical study focused on the diagnostic aids of lesions that demonstrate different clinical, radiologic, and histological findings. Materials and Methods: A total of 16 patients with benign fibrous-osseous lesions on the jaws (6 fibrous dysplasias, 6 ossifying fibromas, 3 cemental dysplasias, and one osteoblastoma) were reviewed. Nine patients with malignant fibrous-osseous lesions (8 osteosarcomas and one Ewing's sarcoma) were also retrospectively reviewed. Results: Osteosarcoma patients complained of facial swelling and tooth mobility. The radiographic findings showed the irregular resorption of cortical bone and periosteal reactions. Histological features included cellular pleomorphism and atypical mitosis. An Ewing's sarcoma patient complained of tooth mobility and facial swelling. Onion-skin appearance and irregular expansile marginal bony radiolucency were seen in the radiography. Fibrous dysplasia patients complained of facial swelling and asymmetry. The radiographic features were mostly ground-glass radiopacity. Histological findings showed a bony trabeculae pattern surrounded by fibrous ground substances. Ossifying fibroma patients complained of buccal swelling and jaw pains, showing expanded cortical radiolucent lesions with a radiopaque margin. Histological findings were revealed as cellular fibrous stroma with immature woven bones. In cemental dysplasia, most of their lesions were found in a routine dental exam. Well-circumscribed radiopaque lesions were observed in the radiography, and cementum-like ossicles with fibrous stroma were seen in the microscopy. An osteoblastoma patient complained of jaw pain and facial swelling. Radiographic findings were mottled, dense radiopacity with osteolytic margin. Trabeculae of the osteoid with a vascular network and numerous osteoblasts with woven bone were predominantly found in the microscopy. Conclusion: Our study showed similar results as other studies. We suggest the clinical parameters of diagnosis and treatment for malignant and benign fibrous-osseous lesions of the jaws.
