background and objective: different mechanisms may lead to the development of soft tissue tumor-like lesions in the oral cavity. many of these lesions can be identified as specific entities on the basis of their histopathological features and are divided into fibrous, vascular, and giant cell types. the purpose of this study was to establish the relative prevalence of the different histopatholo...

Solitary fibrous tumor of the pleura is one of the uncommon diseases. About 40% of solitary fibrous tumors of the pleura are of a visceral and peduncled type. Several visceral pleural tumors have motility. A proof of motility of the intrathoracic tumor is useful for preoperative diagnosis. We report a resected case of solitary fibrous tumor of the pleura presenting dry cough induced by postural...

Three cases of pulmonary osteoarthropathy secondary to pulmonary metastases from extrathoracic tumours are described. Analysis of the reported cases shows that most of them were secondary to osteosarcoma, nasopharyngeal tumour, fibrosarcoma, and uterine tumour. Fibrous tumours and tumours with a predominantly fibrous stroma tend to be associated with osteoarthropathy more than others. This sugg...

We report on a 28-year-old man with severe headache. Imaging studies included CT and MR. A large sphenoid mucocoele was demonstrated as well as findings compatible with fibrous dysplasia of the facial bones. Both disorders had been previously unknown. Imaging findings suggested that the sphenoid mucocoele was related to an obstruction caused by the expansile bone of fibrous dysplasia. These fin...

Hopping provides efficient and energy saving locomotion for kangaroos, but it results in great forces in the knee joints. A previous study has suggested that a unique fibrous cartilage in the central region of the tibial cartilage could serve to decrease the peak stresses generated within kangaroo tibiofemoral joints. However, the influences of the microstructure, composition and mechanical pro...

Fibrous dysplasia is a benign fibro-osseous disease of bone of unknown etiology. Its occurrence in the maxillo-facial region is frequent. Because of the benign nature of the condition, the surgery itself should be relatively conservative. Recently, bisphosphonates have shown progress in the treatment of patients with fibrous dysplasia. In the current case report, combination of enucleation and ...

Malignant fibrous histiocytoma is a high-grade and aggressive sarcoma. It is a type of histiocytoma that is the most common soft tissue sarcoma of late adult life. These tumors rarely involve the head and neck region. Wide excision followed by postoperative radiotherapy is believed to be the treatment of choice for malignant fibrous histiocytoma. We present a rare case of malignant fibrous hist...

BACKGROUND Fibrous hamartoma is the key pathology of congenital pseudarthrosis of the tibia (CPT), which was shown to have low osteogenicity and high osteoclastogenicity. This study further investigated the mechanism of impaired osteoblastic differentiation of fibrous hamartoma cells. METHODS Fibroblast-like cells were obtained from enzymatically dissociated fibrous hamartomas of 11 patients ...

INTRODUCTION Posterior capsule opacification (PCO) is a visually-disabling complication of cataract surgery. OBJECTIVE To estimate energy levels for capsulotomy in various subtypes of PCO (membranous, fibrous and fibro-membranous). MATERIALS AND METHODS A total of 215 patients with PCO were randomly selected and evaluated for Nd: Yag laser capsulotomy, after a quiet post-operative course of...

We report a case of pancreatic hamartoma-like solitary fibrous tumor which was differentiated from pancreatic hamartoma with the detection of NAB2-STAT6 fusion, a specific mutation for solitary fibrous tumors. A pancreatic well-demarcated solid nodule, 21 × 17 mm, of 82-year-old man was surgically enucleated. Microscopic findings were close to a pancreatic hamartoma that consisted of sparsely d...
