Fibrous dysplasia affects principally the bone, it might also comprise extra skeletal anomalies; whereby the bone is replaced by a dysplastic fibrous tissue. It is classified according to the number of affected bones, and its association to endocrine alterations in: monostotic, polyostotic forms and Albright's disease. A congenital etiology is suggested. Pathologic fractures are the most freque...

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, ...

Angiomatoid fibrous histiocytoma is a rare soft tissue tumor of uncertain differentiation and low metastatic potential, which occurs predominantly in children and young adults. It occurs mostly within the extremities, trunk, head and neck. It can be associated with systemic manifestations such as anemia, pyrexia and malaise. Its morphology is distinct, with an outer shell of lymphoid tissue, sh...

Mouth lymphoepithelial cyst is rare, with few cases reported in literature. The aim of this article is to describe a clinical case, focusing on clinical and diagnostic aspects, treatment and prognosis. The lesion was one year old and had developed as a fibrous nodule in the jugal mucosa of a 71-year-old leucoderma patient. Considering focal inflammatory fibrous hyperplasia, fibroma and mucocele...

In the present study, the effects of a fibrous membrane between cement and bone in a femoral total hip replacement were investigated. The study involved the problem of modeling this fibrous membrane in finite-element analyses, and its global consequences for the load-transfer mechanism and its resulting stress patterns. A finite-element model was developed, suitable to describe nonlinear contac...

The central odontogenic fibroma (COF) is a rare benign mesenchymal tumour of jaw bone derived from the ectomesenchyme. It characterized by fibrous mature stroma with variable number strands or islands inactive-looking epithelium. presented case 46 years old male complaining asymptomatic mandibular bony swelling. Radiographically, lesion unilocular radiolucent, root resorption and displacement t...

We report a case of huge pulmonary hamartoma with atrophied right lower lobe in a 33-year-old female patient. The pulmonary hamartoma was solid, 30 × 16.5 × 14.5 cm in size, which sectioned surface reveals a thick-walled fibrous cyst with multiple yellow nodules protruding into the lumen. The tumour was compressing the right lung and there was no evidence of infiltration into the surrounding st...

Giant cell fibroma is an asymptomatic sessile or pedunculated nodule. It is a reactive localized proliferation of fibrous tissue. The appearance is similar to irritational fibroma. It is usually small but in some cases it can be large. A female patient aged 45 years presented with a overgrowth on maxillary gingival in on 12, 13 region. The lesion was asymptomatic, firm and fibrous in consistenc...

objective(s):   gold nanoparticles (gnps) command a great deal of attention for biomedical applications nowadays. the data about the degree of toxicity and the accumulation of gold nanoparticles in-vivo is not enough to judge.  materials and methods:  a total of 32 healthy male wistar rats were randomly divided into 4 including: three gnp-treated and one control group. groups 1, 2 and 3 receive...

Solitary fibrous tumour is an uncommon soft tissue tumour initially described in the pleural cavity. In the past decade, it has been described in various extrapleural sites, including the abdomen. Traditionally regarded as benign, cases of histologically or clinically malignant solitary fibrous tumours are rare. This report describes such a case, although the patient is still disease free five ...
