Purpose: The purpose of this study is to assess magnetic resonance (MR) imaging findings of malignant fibrous histiocytoma (MFH) of bone and to evaluatethe role ofcontrast-enhanced MR imaging in thediagnosis of bone MFH. Materialsand Methods: MR imagingsof pathologicallyproven bone MFH inten patients were reviewed. Enhanced study was also performed with Gd-DTPA. The MR images were evaluated for...

According to the most recent WHO classification (2002 edition), soft tissue malignant fibrous histiocytoma (MFH) is considered to be an undifferentiated pleomorphic sarcoma. MFH is the most common somatic sarcoma involving deep soft tissues (1). The most frequent primary sites of MFH are the lower limbs (49%), upper limbs (19%), and abdominal cavity or retroperitoneum (16%) of adults (2). MFH o...

Malignant fibrous histiocytoma, a type of sarcoma, is a malignant neoplasm with uncertain origin that arises in both the soft tissues and the bone. The occurrence of primary malignant fibrous histiocytoma of the pleura is extremely rare. We report a case of a 65-year-old Korean man who is being diagnosed with primary malignant fibrous histiocytoma of the pleura.

Introduction: Myxofibrosarcoma was originally described as the myxoid variant of Malignant Fibrous Histiocytoma (MFH), a high-grade and aggressive sarcoma, which is very uncommon in the head and neck region, with about 100 cases reported up to now. MFH occurring in the maxillary sinus is so rare that only 23 cases have been reported. We hereby report a case of myxofibrosarcoma in the maxillary ...

Malignant fibrous histiocytoma is a high-grade and aggressive sarcoma. It is a type of histiocytoma that is the most common soft tissue sarcoma of late adult life. These tumors rarely involve the head and neck region. Wide excision followed by postoperative radiotherapy is believed to be the treatment of choice for malignant fibrous histiocytoma. We present a rare case of malignant fibrous hist...

BACKGROUND Primary visceral malignant fibrous histiocytoma (MFH) is a rare disease, and few cases have been reported in the English literature. However, retained foreign bodies in the abdomen after surgical procedures are important causes of intra-abdominal infections. For legal and ethical reasons, there are few publications in the literature. In this article, we describe for the first time a ...

Malignant fibrous histiocytoma (MFH), a high-grade, undifferentiated sarcoma, is highly aggressive, resistant to radiochemotherapy and associated with poor prognosis. There are no specific immunohistochemical markers for its diagnosis. The MFH cell line SFT7913 served as and immunogen for the generation of the FU3 monoclonal antibody in our laboratory. FU3 reacted strongly with MFH cells and wi...

BACKGROUND We present the extremely rare case of a 67-year-old male with malignant fibrous histiocytoma, arising in the lumbar spine, demonstrated with radiological and pathological studies. CASE REPORT The patient and his relatives refused open surgical approach and we performed transpedicular vertebral corpus biopsy and vertebroplasty under spinal anesthesia. His pathological result was mal...

BACKGROUND/AIMS Malignant fibrous histiocytoma (MFH) of bone, a relatively rare primary malignant bone tumour, is a distinct clinicopathological entity as opposed to MFH derived from soft tissue. Although the true histogenesis of this condition is still controversial, a considerable number of cases of MFH in soft tissue show positive immunohistochemical reactivity for muscle markers such as des...
