Cranial malignant fibrous histiocytomas are rare tumors. Most are hypervascular, destructive masses that are similar to other malignant lesions and to malignant fibrous histiocytomas found elsewhere in the body. We describe a myxoid malignant fibrous histiocytoma of the temporal bone, possibly of dural origin, with features that more closely resembled a meningioma at CT, MR imaging, and angiogr...

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.

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...

Malignant phyllodes tumor is usually diagnosed by the presence of benign duct-like epithelium and malignant mesenchymal tissue. In addition to the usual fibrosarcomatous features, the mesenchymal component may show areas resembling osteogenic sarcoma, chondrosarcoma, liposarcoma, leiomyosarcoma, rhabdomyosarcoma, malignant mesenchymoma, and, very rarely, malignant fibrous histiocytoma. We prese...

Malignant fibrous histiocytoma (MFH) is an aggressive soft tissue sarcoma occurring in the late adulthood. It may rarely arise as a primary neoplasm in bone, but usually in the long bones and accounts for less than 1% of the malignant tumors of bone. Its presentation in the facial bones and skull is extremely rare. Malignant fibrous histiocytoma of bone is a highly malignant tumor that recurs, ...
