A malignant fibrous histiocytoma is a malignant soft tissue neoplasm that occurs frequently in the metaphyseal ends of the long bones of adults. The lung is a common site for metastasis but it is a rare site for a primary malignant fibrous histiocytoma. Here we report a case of a primary malignant fibrous histiocytoma of the lung. The patient was a 53-year-old man who presented with a moderate amount of a left pleural effusion and an illdefined mass in the left lower lobe on a chest radiograph and a local invasion to the left 10th and 11th rib on chest CT. Under the strong suspicion of lung cancer with a pleural invasion, a serial diagnostic thoracentesis was performed. The cytologic examination of the pleural effusion revealed no malignant cells. Consequently, a thoracoscopic pleural biopsy was performed. The histological examination revealed slender spindle cells and scattered epitheloid cells arranged in a vague storiform or a whirling pattern. Immunohistochemicaily, the tumor cells tested positive for vimentin and negative for cytokeratin, desmin, CD 34 and PAS. These features were consistent with a malignant fibrous histiocytoma. This case is an unusual addition to the small number of published reports on a primary malignant fibrous histiocytoma of the lung.

At OPD follow-up in December 1998, chest x-ray of a 42-year-old female showed a solit ary pulmonary nodule at a superior basal segment in the right lower lobe. After percut aneous transthoracic needle aspiration failure, wedge resection of the superior basal segment of lower lobe in right lung was performed for diagnosis and therapy. Three years ago, she had received surgery to remove a mass in the left buttock. The mass was pathologically diagnosed as malignant fibrous histiocytoma. She subsequently received 4500 rad radiotherapy for 35 days. Pathology confirmed metastatic malignant fibrous histiocytoma of the lung.

Malignant fibrous histiocytoma after radiation therapy is very rare and its prognosis is poor. A 52-year-old male patient was admitted due to painful mass at the sternal area which developed 6 months ago. The patient had a history of radiation therapy for esophageal cancer 5 years ago. The incisional biopy disclosed sternal sarcoma. In spite of 5 cycles of chemotherapy, the m ss progressively enlarged, and an operation was performed. Total sternectomy with overlying skin and postal cartilage was performed and reconstruction was carried out with autologous rib bone graft, bilateral pectoralis klajor muscle flap and skin graft. The microscopic examination was consistent with malignant fibrous histiocytoma. The postoperative course was uneventful and the patient was discharged on postoperative 36 day.

Malignant flrous histiocytoma is a rare deep-seated pleomorphlc sarcoma, although its incidence Increasing. In this report, we present a case of a malignant fibrous histiocytoma, arising in the left chest wall in a 37-year-ol4 male patient. He underwent radical on bloc resection which include excision of tumor on left upper chest wall with resection of ribs from the first to third, left upper lo ectomy and chest wall reconstruction with Marled Mesh. However, he had local recurrence and distant metastasis within 12 months of the original operation. Malignant fibrous histiocytoma is an agrressive disease entity, with a propensity for early and distant spread.

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.

Angiomatoid fibrous histiocytoma is a rare soft tissue tumor that generally affects children and young adults. We report a case of angiomatoid fibrous histiocytoma in an 11-year-old boy who complained of a back mass for 3 years. Surgical excision was performed. The excised specimen showed a $4.0{\times}3.6{\times}3.0cm$, well circumscribed, grayish white tumor, with multicystic changes. Histological examination showed proliferation of spindle or round shaped tumor cells. There was a dense fibrous pseudocapsule with prominent chronic inflammatory cell infiltrates.

Purpose: Malignant fibrous histiocytoma (MFH) is mainly a soft tissue sarcoma containing fibroblast-like cells and histiocytic cells. MFH in bone accounts for 5% of all malignant bone tumors. MFH of the maxilla is extremely rare and difficult to diagnose due to its scarcity. Treatment mainstay is a complete surgical excision. Radiation therapy is also available when surgery alone is incomplete. Prognosis is not clear but can be devastating. Authors report one case of MFH developed in the maxilla. Methods: A 24-year-old man firstly diagnosed as fibrous dysplasia based on CT findings. Considering facial contour, partial excision was done. But pathology report confirmed malignant fibrous histiocytoma and secondary wide excision was done including zygoma and grossly all affected area. After surgery, radiation therapy was continued. Results: There are no evidence of tumor recurrence after clinical and radiological treatment. Conclusion: MFH of maxilla is very rare and this can leads to misdiagnosis in many clinicians. Surgeon should differentiate this disease from fibrous dysplasia and pathology and MRI are accurate methods for diagnosis of MFH.

Malignant fibrous histiocytoma is one of the rare types of larynx tumor. The most common sites of the tumor are limbs, trunk, and retroperitoneal space, but tumor localization within head and neck are very rare. It is built of histiocytes, fibroblasts and multinuclear giant cells. A diagnosis of the tumor includes microscopic and immunohistologic examination with identification of specific tissue markers and intermediate filaments of proteins. This disease has been treated by several methods combining radical surgery, radiotherapy, and chemotherapy, but the prognosis is poor. We present 74-year-old Asian man with dysphonia for 2 years. The tumor of the larynx was examined on laryngoscopy. The radical surgery rendered the final pathological diagnosis, confirmed histologically and immunohistochemically as malignant fibrous histiocytoma. This tumor was treated with laser cordectomy followed by radiotherapy. 3.5 year's observation of the patient didn't either show any signs of recurrence or dysphonia.

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.
