Primary benign fibrous histiocytoma involving the central nervous system is an exceedingly rare tumor with most cases originating from the dura or parenchymal tissue. Diagnosis of primary benign fibrous histiocytoma is difficult due to its confusing histopathological characteristics. Two cases of primary intracranial benign fibrous histiocytoma mimicking parasagittal meningioma are presented in...

Fibrous dysplasia is classified among benign bone tumors. It is a bone development anomaly characterized by hamartoma proliferation of fibrous tissue within the medullary bone, with secondary bony metaplasia, producing immature, newly formed and weakly calcified bone, without maturation of the osteoblast. It can be monostotic or polyostotic. The craniofacial localization occurs in 10%-25% of ca...

Benign fibrous histiocytoma or dermatofibroma is one of the most common types of benign, cutaneous, soft tissue tumors, most often found in the middle-aged adults. The diagnosis of dermatofibroma/benign fibrous histiocytoma is usually straightforward if the typical morphological features are present. However, some diagnostic difficulties may arise when one is dealing with some unusual morpholog...

Fibrous dysplasia; Nasal cavity; Skull base; Endoscopic sinus surgery Abstract Fibrous dysplasia is an uncommon benign tumour in the nasal cavity. Due to adjacent vital soft tissue structures surgery is often the treatment of choice. We report a rare case of polyostotic fibrous dysplasia of the mandible and the ethmoid bone including nasal bony septum with intracranial expansion, and include a ...

A benign bone neoplasm known as an osseous fibroma is frequently referred fibro-osseous lesion. It has a stronger preference for females and thought to have originated from periodontal membrane. Maxilla less often afflicted than the mandible. This made up of highly cellular, fibrous tissue with varied levels calcified tissue, which may resemble cementum, bone, or both. Depending on degree calci...

Vestibular stenosis is an uncommon but debilitating cause of nasal obstruction leading to serious impairment airway. It caused by granulation and fibrosis vestibular lining there circumferential scar retraction in the inlet cavities. Stenosis may be congenital or acquired. Causes acquired include burns, trauma, infections, iatrogenic insult vestibule. Surgical correction usually done excision f...

The genus Cyperus with five subgenus and 29 species, is the second largest genus of Cyperaceae family in flora of Iran. In this research, stem and leaf anatomy of 10 species belonging to subgenus Cyperus is investigated. The stems in transverse section of all examined species were triangular except for C. bulbosus which was subterete to polygonal. The ground tissue was spongy with numerous and ...

Case Description- A seven-year-old male donkey was admitted with a history of left scrotal swelling with ulcerating wound since 2 years.Clinical Findings- The left scrotum was painful. There was ulcerating and hypergranulating wound discharging bloody discharge. The wall of the scrotum was found thick and infiltratedwith soft slimy non capsulated and lobulated fibrous tissue masses. The left te...

Introduction: Flabby or fibrous ridge is one of the consequences of long term wearing of complete dentures. It can develop where hyperplasic soft tissue replaces the alveolar bone and is a common finding, particularly in the upper anterior region of long term denture wearers. Forces exerted during impression making can result in distortion of the mobile tissue unless managed appropriately; such...

This study focuses on the formation of lesions of atherosclerosis in the aortas and iliac arteries of nonhuman primates (Macaca nemestrina) maintained on a low level hypercholesterolemic diet (plasma cholesterol 200 to 400 mg/dl) for 2, 3, or 3.5 years. Advanced lesions, or fibrous plaques, were found in all of the animals. The extent and severity of the lesions were closely related to the leve...
