we report here a rare case of lateral ectopia of thyroid without orthotopic thyroid tissue in an indian teenager, who was referred to our department for a thyroid scintigraphy. technetium pertechnetate (99mtco4- ) scan showed uptake in laterally placed soft tissue structure along with functioning thyroid tissue in high anterior midline neck region in line with thyroglossal tract. there is no up...

sarcoidosis is a systemic disease that is characterized with noncaseating granulomatous nodules which present in multiple organs specially lungs (90%) . incidence of masses due to sarcoidosis in upper extremity is low and most cases present in association with involvement of pulmonary hilary lymph nodes. in this article we present a rare case of sarcoidosis which presented as a single soft tiss...

Bioscaffolds derived from animal tissues can be an appealing substrate to induce the formation of functional tissue (histogenesis) within the context of tissue engineering. Bioscaffolds obtained from the extracellular matrix not only contain collagen, which can provide mechanical support, but also include the required biologically active molecules that provide a stimulus for active tissue remod...

Soft tissue modeling for the creation of a haptic simulator for training medical skills has been the focus of many attempts up to now. In soft tissue modeling the most important parameter considered is its being real-time, as well as its accuracy and sensitivity. In this paper, ANFIS approach is used to present a nonlinear model for soft tissue. The required data for training the neuro-fuzzy mo...

Introduction: Coverage of bone grafts is very important in reconstructive surgery. In edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. Here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for up...
