Introduction: There is many ways to assessing the electrical conductivity anisotropyof a tumor. Applying the values of tissue electrical conductivity anisotropyis crucial in numerical modeling of the electric and thermal field distribution in electroporationtreatments. This study aims to calculate the tissues electrical conductivityanisotropy in patients with sarcoma tumors using diffusion tens...

Introduction: Ewing sarcoma family of tumors (ESFT) are a group of small round cell tumors showing varying degrees of neuroectodermal differentiation with Ewing sarcoma being the least differentiated. Primitive neuroectodermal tumors (PNET) show neuroectodermal differentiation by light microscopy, immune histochemistry (IHC) or electron microscopy [1]. According to WHO classification of bone an...

Walleye dermal sarcoma virus (WDSV) has been identified as the causative agent of a benign neoplasia of walleye Stizostedion vitreum, walleye dermal sarcoma (WDS). We conducted an experimental transmission regimen to determine if WDSV is capable of inducing dermal sarcoma in the closely related sauger S. canadense. Nearly all of young-of-the-year saugers (96%) inoculated with filtrates of sprin...

anatomy: middle cranial fossa mainly floored by sphenoidal bone and located post. to innominate bone or lesser wing and ant. to temporal bone. main foramens are located in deep part, bilateral to sellae are orbital fissures, optic canals, foramen rotundom, ovale and spinosum, foramen lacerum also meckle cave or trigeminal impression and carotid canal. this fossa is like a butterfly in shape. le...

Highlights The article describes a rare case of surgical treatment pulmonary artery intimal sarcoma. authors analyzed the causes for incorrect diagnosis embolism in detail, and proposed alternative options distinguishing diseases under consideration. Moreover, different modalities intracardial sarcomas, demonstrated prospect using molecular hydrogen as component an anesthetics during interventi...

An overview of the presentation, clinical and radiographic features, and management of the most common benign pediatric bone tumors will be presented below. Malignant bone tumors (Ewing sarcoma and osteosarcoma) are discussed separately. (See "Clinical presentation, staging, and prognostic factors of the Ewing sarcoma family of tumors" and "Osteosarcoma: Epidemiology, pathogenesis, clinical pre...

here, we describe young men with synovial sarcoma in the palatine tonsil, who presented with a 3-4 month history of progressive sore throat, tonsillar ulcerative mass and bleeding. clinical and radiological examinations revealed that the tumors arose from the palatine tonsil and extended to the parapharyngeal space. both tumors were too advanced to remove completely; therefore, they underwent s...

background ewing’s sarcoma family is a group of small round cells tumors. the aim of this study is to evaluate clinicopathologic characteristics and outcome of ewing’s sarcoma in children and adolescents in yazd, iran. materials and methods all patients under 19 years with documented pathology of ewing’s sarcoma family tumor who referred to shahid ramazanzadeh radiotherapy center between 2002 t...

BACKGROUND & OBJECTIVE Peripheral tumor growth pattern plays an important role in the local recurrence and metastases of soft tissue sarcoma. This study was to determine the peripheral growth pattern of soft tissue sarcoma by magnetic resonance imaging (MRI), explore its correlation to histological grade, and assess biological features of soft tissue sarcoma before operation. METHODS MRI was ...

Peripheral neuroepitbelioma (PN) is a rare highly malignant tumor, classified in the group of small round cell tumors. We report eight cases of PN, based on histologic appearance and immunohistochemical staining for neuron-specific enolase (NSE). Electron microscopy was also performed in three cases. The tumors exhibited rapid local growth, leading to limb amputation in five cases. Histolo...
