a unique case of xanthoma in the external ear canal pediatric patient is presented this report. We describe and resume current literature on xanthomas head neck area. clinical intraoperative findings are reported presumed mechanisms for emergence discussed. furthermore described pathologic immunohistochemical characteristics. mostly seen patients with lipid metabolism disorders or hyperlipidemi...

In this work we investigate an inverse geometry problem. Given a light source, a diffuse plane and a caustic image, how must a geometric object look like (transmissive or reflective) in oder to project the desired caustic onto the diffuse plane when lit by the light source? In order to construct the geometry we apply an analysis-by-synthesis approach, exploiting the GPU to accelerate caustic re...

SUMMARY The reconstruction of complex facial soft-tissue defects is a challenge that is often encountered by the plastic surgeon. Careful planning and knowledge of the aesthetic subunits that border the defect are paramount to achieve optimal results. We present a case of a 56-year-old woman who underwent excision of a large disfiguring chronic xanthelasma that extended from canthus to canthus ...
