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 ...

background & aim: malignant fibrous histiocytoma (mfh), is the most common soft tissue sarcoma in adults and is frequently seen is elderly. this lesion is so rare in bones and if seen, is common in long bones and the incidence of the lesion in maxillofacial bones is uncommon. in addition, maxilla is an unusual site for malignant fibrous histiocytoma (mfh). the aim of this article was to report ...

although the majority of mesenchymal lesions of the gastrointestinal tract are neoplastic in nature, but nonneoplastic reactive processes may also involve the gastrointestinal tract and mesentery. some more aggressive neoplasms located in same area, such as fibromatosis or gastrointestinal stromal  tumors  may  be  cause  of  diagnostic  confusion.  reactive  nodular  fibrous  pseudo  tumor (rn...

conclusions this is the first case of sft of the retroperitoneum removed laparoscopically. the laparoscopic approach is useful for the advantages of minimally invasive surgery especially in case of peduncolate tumor as the case reported. case presentation a 29-year-old female, was admitted in the gynaecology and obstetrics unit, for suspected pelvic tumor. ct scan showed a mass with hypervascul...

in this research, a novel method to decrease micro-residual stresses of fibrous composites by adding carbon nanotubes (cnts) is proposed in detail. the negative coefficient of thermal expansion and the high young’s modulus of cnts can be utilized to counterbalance the process induced residual stresses in composites. to this end, first, the effects of adding cnts to the matrix of fibrous composi...

fibrous dysplasia of the bone (fdb) is a common, genetic, developmental disorder with a benign course. fdb can be seen anywhere throughout the skeleton. it is usually asymptomatic and found incidentally on imaging studies that are performed for other purposes. although whole body 18 f-flourodeoxyglucose pet/ct (fdg pet/ct) is widely used in tumor imaging, infections and benign pathologies like ...

herein, we report the f-18 fluorodeoxyglucose (18f-fdg) positron emission tomography (pet)/computed tomography (ct) findings of a benign solitary fibrous tumor (sft) of the kidney. the patient was a 63-year-old woman with a mass in the right kidney (10×9.7 cm), incidentally found on ct images. the ct scan showed a lobulated tumor arising from the hilum of the right kidney. the tumor consisted o...
