We describe the first case of the coexistence of the hereditary connective tissue disorder multiple exostoses (HME) and an acquired connective tissue disorder manifest by the overlap of dermatomyositis (DM), scleroderma (PSS), high titre speckled pattern antinuclear antibodies, and increased antibodies to double stranded deoxyribonucleic acid (DNA). Furthermore this patient developed chondrosar...

necrotizing fasciitis is a part of a spectrum of necrotizing soft tissue infections that usually follow a surgical intervention or a chronic / acute medical illness. diagnosis is often based on symptoms which classically start within hours after an injury. there are no reports on the use of pet/ct in this condition. sparing reports of its association in patients with malignancy (ca of colon and...

objective: the aim of this study is to evaluate the effect of tissue composition on dose distribution in electron beam radiotherapy. methods : a siemens primus linear accelerator and a phantom were simulated using mcnpx monte carlo code. in a homogeneous cylindrical phantom, six types of soft tissue and three types of tissue-equivalent materials were investigated. the tissues included muscle (s...

Dermatofibrosarcoma protuberans is a rare soft tissue neoplasm arising from mesenchymal cells, making up about 6% of all soft tissue tumours. Often found on the scalp, neck, trunk and extremities, it has an intermediateto low-grade malignancy potential except the fibrosarcomatous variant (high-grade), which is more likely to metastasize than other types. Here we present the case of a 46-year-ol...

in this paper an automatic examination robot was developed to improve the process of cancer detection, tumor localization and geometrical shape diagnosis. a uniformly distributed compressive load was applied to the top tissue surface and the resultant mechanical stress was measured that was employed for the tumor diagnosis task. the experimental examinations were performed on the soft tissue of...

needle insertion is a minimally invasive technique in diagnosing and treating tumors. however, to perform a surgery accurately, the tissue should have minimum amount of displacement during needle insertion so that it reaches the target tissue. therefore, the tissue membrane has to move less to decrease rupturing under the membrane. in this study, the effect of different design parameters on dis...
