basal cell carcinoma (bcc) is the most common cutaneous malignancy among caucasians. rare examples of aggressive and neglected bcc have been reported. here we report a unique case of a neglected bcc with significant jaw involvement. a 50-year-old female, referred by an otorhinologist, presented with a large ulcer on her chin, which was extended to her mandibular vestibule. the ulcer was 9×5.5 c...

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...

purpose : to present a case of missed intraorbital wooden foreign body presented as soft tissue mass case report : we introduce a case of intraorbital wooden foreign body which presented with orbital soft tissue mass two years after trauma. a plain ct was requested which revealed a foreign body in the right orbit.conclusion : it is frequently difficult to identify and localize organic intraorbi...

Prostate adenocarcinoma is the most common malignancy and the second leading cause of cancer related deaths in men. Testicular liposarcomas are uncommon soft tissue neoplasms. We report coexistence of prostate cancer and testicular liposarcoma in a 69 year-old-man because while orchiectomy endications are decreasing day by day, these second malignancies should not be missed.

This contribution presents an approach to the diagnosis of symptoms referable to spinal pathology in patients with known malignancy. Pain and neurological disturbance are distressing and disabling symptoms, which in patients with cancer may be a result of bony metastases, paraspinal soft tissue disease and meningeal and intra-axial spinal metastases. Imaging studies are pivotal, and typical and...
