Case Description- A pigeon with an abnormal mass on right wing was referred to the Veterinary Clinic of Shahid Bahonar University of Kerman. Treatment and Outcome- The mass was removed surgically and histopathologic examination was done. Microscopic findings revealed a stori-form pattern of atypical and pleomorphic spindle-shape tumor cells with histiocytes and too many thick wall capillari...

SUMMARY Occurance of Malignant Fihrous Histiocytoma (MFH) of the spermatic cord as a primary source is so rare that since I 967 Just 12 of such cases have heen reported (4,8, 10). MFH is one of the pleomorphic soft tissue Malignant tumors which has been studied for first time by Ozzello and Co workers on 1963. The Tumor ong1nates from primary Mesenchymal cells which have both histocytic & fi...

A paratesticular fibrous pseudotumor is a relatively rare benign disease. Preoperatively diagnosing a fibrous pseudotumor is challenging because distinguishing these masses from malignant tumors on the basis of clinical and radiological findings can be difficult. We present a case of a 28-year-old man who presented with a painless palpable mass in the right scrotum; the fibrous pseudotumor of t...

Fibrous dysplasia (FD) is a rare bone disorder in which the affected replaced by abnormal scar-like(fibrous) connective tissue. This fibrous tissue makes weak, abnormally fragile and proneto fracture. Pain may occur areas. condition was first described 1942 Lichtenstein andJaffe, also referred as Lichtenstein-Jaffe disease. Anyone can have FD it be diagnosed at any age. FDcan affect one (known ...

BACKGROUND AND PURPOSE Acute cerebral ischemic events are associated with rupture of vulnerable carotid atheroma and subsequent thrombosis. Factors such as luminal stenosis and fibrous cap thickness have been thought to be important risk factors for plaque rupture. We used a flow-structure interaction model to simulate the interaction between blood flow and atheromatous plaque to evaluate the e...

a Cancer stem cells (CSCs) are hypothesized as tumor-initiating cells within tumors and main contributors of tumor growth, metastasis and recurrence. Mammary cancer cells, MCF-7 cells, were cultured on 3D polycaprolactone (PCL) fibrous scaffolds, showing an increased proportion of CSCs. The expression of stem cell markers, including OCT3/4 and SOX2, and breast CSC-specific markers, SOX4 and CD4...

Polylactide (PLA) electrospun fibers have been reported as a scaffold for bone tissue engineering application, however, the great hydrophobicity limits its broad application. In this study, the hybrid amphiphilic poly(ethylene glycol) (PEG)/hydrophobic PLA fibrous scaffolds exhibited improved morphology with regular and continuous fibers compared to corresponding blank PLA fiber mats. The prepa...

PURPOSE To study the spatial arrangement of the fibrous elements that form the leaflets of the mitral valve and its fibrous ring. METHODS The study of 20 human adult hearts, of both sexes, fixed in 10% formaldehyde solution was made. The mitral valves with their fibrous rings and small parts of the adjacent atrial and ventricular muscles were removed. Part of this material was embedded in par...

Intrascrotal benign fibrous proliferations are uncommon and mostly arise from paratesticular region falling into the category of fibrous pseudotumor which is characterized by nodular growth composed of probably reactive proliferation of fibroblasts and inflammatory cells. Although benign, this often clinically mimics intrascrotal malignancy and usually remains undiagnosed preoperatively. Here, ...

Fibrous dysplasia involving the thoracic spine is very rare. This patient had monostotic fibrous dysplasia involving the vertebral body, posterior elements, and right seventh rib with focal neurologic signs. The radiographic and bone scan findings are shown. The patient was treated successfully with tumor resection and arthrodesis using combined anterior and posterior approaches. Although fibro...
