Chondromyxoid fibroma is a rare benign cartilaginous neoplasm that mostly affects the metaphyseal region of the long bones. The tibia, small tubular bones of the foot, the distal femur and pelvis are common locations, but involvement of the vertebral bones, especially the cervical vertebra, is very rare. Radiographic features show typical characteristics and this tumor often presents as a lobul...

Rhabdomyosarcoma (RMS) is a rare malignant soft tissue neoplasm comprised of cells derived from the primitive mesen¬chyme. About 35% of RMS arises in the head and neck, are are classified as parameningeal and non-parameningeal forms. These are the most common soft tissue sarcoma of the children, adolescents and young adults. Their etiopathogenesis and its molecular relevance have been emphasize...

A disfiguring and debilitating neoplastic condition known as devil facial tumor disease (DFTD) has been discovered in wild Tasmanian Devils (Sarcophilus harrisii) across 51% of its natural range, with population declines of up to 80% in some areas (C. Hawkins, personal communication). Between 2001 and 2004, 91 cases were examined. The tumors presented as large, solid, soft tissue masses usually...

BACKGROUND Leiomyosarcomas of soft tissue are malignant tumours that are not infrequently encountered in clinical medicine and histopathology. Such sarcomas of the eye are, however, a rare occurrence. PURPOSE Herein, the histopathological features of a case of conjunctival leiomyosarcoma are described. A 38-year-old HIV-positive male, who was otherwise fit and healthy, presented with redness ...

a pseudo aneurysm results from leakage of blood from an artery after trauma or dehiscence or separation of a surgical anastomosis. the reported rate of pseudo aneurysm in access sites range from 0.88% to 8%. it has some cause like penetrating trauma, blunt trauma and endovascular procedure. the differential diagnoses of this lesion are hematoma, av fistula, lymphadenopathy, lymphocele, dvt, com...

a case of soft tissue defect of dorsal hand due to crush injury in a 37-year-old female is reported here. the reconstructive surgery was performed for the hand soft-tissue defect. among different flaps used in the surgery, the regional flap such as radial forearm flap can be done. but usually it is not accepted by patient because of cosmetic appearance. therefore, random pattern abdominal flap ...

nowadays, one of the main problems encountered in minimally invasive surgery and telesurgery is the detection of arteries in tissue. in this study, for the first time, tactile detection of an artery in tissue and distinguishing it from the tumor has been modeled by finite element method. in this modeling, three 2d models of tissue have been created: tissue, tissue including a tumor, and tissue ...

normal 0 false false false en-us x-none ar-sa background: robotic needle insertion in biological tissues has been known as one the most applicable procedures in sampling, robotic injection and different medical therapies and operations. objective: in this paper, we would like to investigate the effects of angular velocity in soft tissue insertion procedure by considering force-displacement diag...

conclusion our preliminary results have shown that although there is some overlap between benign and malignant tumors, adding dwi, mr imaging to routine soft tissue tumor protocols may improve diagnostic accuracy. results there was only one patient with a malignant cystic tumor and was not included in the statistical analysis. the median adc values of benign and malignant tumors were 2.31 ± 1.2...

in this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. the polymers were characterized by nuclear magnetic resonance (nmr) spectrometry, fourier transform infrared spectroscopy (f...
