Malignant fibrous histiocytoma of the bone is a very rare tumour mainly affecting long bones, and the most common presenting symptom is local pain. A case of malignant fibrous histiocytoma presenting with pyrexia of undetermined origin and arising in the sternum, a localization not previously described, is reported. The patient died with septic shock after multi-drug chemotherapy including high...

Paratesticular malignant fibrous histiocytoma is an extremely rare malignancy of the scrotum. This malignancy has rarely been described in the literature and scant information exists on the optimal management of this cancer. We present here a case of a 57-year-old man with a diagnosis of high-grade malignant fibrous histiocytoma of the left intrascrotal region who underwent radical orchiectomy,...

The vast majority of soft tissue sarcomas metastasize initially to the lungs. We report a 71-year-old woman with malignant fibrous histiocytoma of the right buttock and thigh that metastasized to the bilateral adrenal glands without development of pulmonary metastasis. Whole-body [F-18]FDG PET-CT showed abnormal tracer uptakes in the bilateral adrenal glands in addition to high accumulation in ...

Aims—To investigate the types and the frequencies of H-ras-1 gene mutations in malignant fibrous histiocytomas. Methods—Thirty five samples of malignant fibrous histiocytoma tissue were searched for point mutations within “hot spot” codons 12 and 13 of the H-ras-1 oncogene by the specific “nested” polymerase chain reaction followed by restriction fragment length polymorphism (PCR-RFLP) and a di...

The fibrous tumors of the pleura are rare primary tumors, accounting for 5% of malignant pleural neoplasms, which generally originate from sub-mesothelial mesenchymal tissue of the visceral pleura. These tumours generally exhibit clinical benign behavior although 12% of solitary fibrous tumors can be malignant and have worse outcomes. These tumors are considered "giant" when the lesion > 15 cm....

The authors report the successful surgical and chemotherapeutic management of a malignant fibrous histiocytoma with localization in the heart. This rare malignancy has specific morphologic characteristics and is diagnosed in adults when it is already locally aggressive or metastasized. The average survival time for patients with malignant fibrous histiocytoma is < 12 months. Neither clinical no...

Primary malignant fibrous histiocytoma (MFH) of the lung is extremely rare although it is among the most common soft tissue sarcomas in adults. Surgery is the primary mode of therapy, with high rates of local and distant recurrence, while radiation therapy appears to be a very useful adjunct, decreasing local relapse. We report a case of primary malignant fibrous histiocytoma of the lung. Fourt...

A 64 year old man was admitted to hospital due to dyspnoea and stridor. A peduncular polyp of the carina was found at bronchoscopy. Histological examination of the tumour after resection with endoscopic electronsurgery revealed malignant fibrous histiocytoma (MFH) of myxoid type. With endoscopic neodymiumyttrium aluminium garnet (Nd-YAG) laser surgery, residual tumour was eliminated. To our kno...

Symptomatic mitral stenosis caused by a left atrial mass as the first sign of metastasis of a malignant tumor is extremely rare and frequently associated with poor prognosis. We report a case of a 59-year-old man with a history of grade 3 malignant fibrous histiocytoma on his left tigh treated by limb-sparing surgery 17 months earlier, who was admitted with 10-days of worsening dyspnea. Imaging...
