Malignant Fibrous Histiocytoma (MFH) is the most common soft-tissue sarcoma which predominantly surfaces in the retro-peritoneum and extremity. MFH of lung is a very rare condition. The diagnosis is essentially through histologic examination. However, the invasion of the chest wall or other organs might help establish the malignant nature.We report a case of a 77-year-old man who had been prese...

Purpose. Transmission of malignant tumour cells to a bone graft donor site is a rare complication of bone grafting.We report a case of seeding of malignant fibrous histiocytoma from the femur to a pelvic bone graft donor site.Discussion. We review the literature, discuss the possible mechanism of tumour transfer and offer advice aimed at avoiding this complication.

To the editor: Soft tissue sarcomas are neoplasms which establish themselves on structures of mesodermic origin. The most common histological variant in adults is the malignant fibrous histiocytoma (MFH), though this rarely occurs in the lung. Furthermore, before labeling such a histiocytoma as being of pulmonary origin, it is important to rule out the possibility of a primary site elsewhere, g...

Aneurysmal fibrous histiocytoma is a different variant of dermatofibroma, characterized by blood-filled spaces within the fibroblastic tumor. In addition to the typical features of a dermatofibroma, it contains large cleft-like or cavernous blood-filled spaces with numerous hemosiderin pigments. This tumor accounts for less than 2% of all fibrous histiocytomas, and it is typically known to occu...

0.1%–0.2% of all malignant tumours and about 15% of all sarcomas. Liposarcoma is the most common type of retroperitoneal sarcoma (41%), followed by leiomyosarcoma, malignant fibrous histiocytoma, fibrosarcoma and other undifferentiated sarcomas. We report the case of a woman with a giant retroperitoneal sarcoma and show that large tumour size is not necessarily a contraindication to surgical ex...

Malignant fibrous histiocytoma (MFH), a type of sarcoma, is a malignant neoplasm with uncertain origins that arise from both the soft tissues and the bone. The occurrence of MFH on the chest wall is extremely rare. We hereby report a case of a 72-year-old woman who was incidentally detected with MFH after a traffic accident.

Retroperitoneal tumours are extremely rare neoplasms, most of them malignant. We described the case of a 48-year-old man with a large retroperitoneal mass detected during the study of a constitutional syndrome. The mass was treated surgerically and pathological diagnosis was malignant fibrous histiocytoma. Literature is reviewed and clinical features, histological findings, radiological techniq...
