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.

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.

Purpose: Malignant degeneration of fibrous dysplasia is an uncommon recognized complication of this disease. Especially, degeneration of fibrous dysplasia to malignant fibrous histiocytoma(MFH) in facial bone is rare and the publications had been limited. The purpose of this report is to share our experience. Methods: A 46-year-old patient with facial fibrous dysplasia visited our clinic for recent facial tingling and swelling. Malignant degeneration of fibrous dysplasia was suspected. Results: Total excision of the mass and adjacent facial bone was performed. Defect was immediately reconstructed with bone graft and bone cement. At a month follow up, metastasis was detected at ipsilateral parotid gland. Superficial parotidectomy and neck dissection was performed. The patient is currently taking chemotherapy. Conclusion: Because of the uncommon presentation of this entity, clinical course of treatment was dependent on other histological types of malignant degeneration. We report this case to share our experience.

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.

We describe herein an extremely rare case of a recurrent primary pulmonary malignant fibrous histiocytoma 3 months after operation that occurred in a 55-year-old man who was treated with chemotherapy and radiotherapy successfully. Until now, 36 months later, the patient has shown no evidence of tumor recurrence. The clinical, radiographic, and pathologic features are reported here together with a brief review of the literature.

Malignant fibrous histiocytoma was classified as fibrosarcoma, liposarcoma, rhabdomyosarcoma in times past and it was first introduced in 1963 to refer to a group of soft tissue tumors and reported in bone in 1972. It was postulated that the origin of tumor cell was derived from histiocytes that could assume the appearance and function of fibroblasts("facultative fibroblasts") at first. But, recently the immunohistochemical studies suggested origin from a primitive mesenchymal cell. The malignant fibrous histiocytoma were commonly misdiagnosed as other tumors such as myxoid liposarcoma, pleomorphic rhabdomyosarcoma, osteogenic sarcoma, leiomyosarcoma, malignant schwannoma, giant cell tumor, hemangiopericytoma, dermatofibrosarcoma protuberans due to the broad morphologic spectrum. The seventeen cases of the malignant fibrous histiocytomas diagnosed at Hanyang University Hospital since 1979 were reviwed, and the suggestions are as follows : 1. No fundamental histologic differences between the MFHs of soft tissues and bones. 2. The other tumors must be excluded in order to diagnose MFH due to wide histologic variety of MFH. 3. The review of the initial tissue slide was necessary for adequate diagnosis because the recurrent MFHs showed different histologic findings from original tumors.

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.

A case of malignant fibrous histiocytoma [MFH] of left pulmonary artery was reported in the 27 year-old male. He was admitted because of hemoptysis for several times. Chest x-ray revealed nodular lesions in left hilar area and left upper lobe. A left thoracotomy was performed followed left upper lobectomy. The main tumor was originated from the pulmonary arterial bifurcation and proximal portion of the left pulmonary artery. By light microscopy, there were many pleomorphic giant cells, which displayed the storiform pattern. And in those area, dilated or compressed vascular channels were involved by tumor cells, suggesting origin of This tumor. Pulmonary artery angiography and chest CT revealed this tumor was originated from pulmonary artery. It would be the first reported primary malignant fibrous histiocytoma of the pulmonary artery in our country. Postoperative prognosis was uneventful, but recently he was suffered from dyspnea, that was noticed by OVD follow-up for 1 month, probably the heart failure sign due to pulmonary arterial flow obstruction.

A case of primary malignant fibrous histiocytoma(MFH) of the lung occurring in a 62-year-old man is presented. After preoperative bronchial blushing and washing cytologic diagnosis of poorly differentiated carcinoma, surgical resection and lymph nodes dissection were performed. Subsequent histologic examination revealed a primary MFH. The diagnosis was confirmed by electron microscopic and immunohistochemical examinations. The review of the bronchial brushing and washing cytologic features disclosed many bipolar and a few unipolar spindle tumor cells with a "comel" configuration, mainly single cells, but also forming loose clusters. The nuclei were elongated and hyperchromatic and contained one or more irregular nucleoli. Scattered bizarre, multinucleated tumor giant cells were also present.
