Kaposi`s sarcoma (KS) is an unusual multifocal neoplasm of vascular endothelial cell origin. The trunk, arms, head, and neck are the most common sites. It is common in men and has four distinct variants: classic, Africa-endemic, immunosuppressive drug-associated, and acquired immunodeficiency syndromeassociated KS. KS appears to develop immunosuppressed patients, but is uncommon in patients on dialysis. A 79-year-old man on hemodialysis for 2 months presented with pruritus over the entire body and multiple, discrete, variable-sized, dark blue papulonodules (papuloplaques, maculopapules) on the left arm and shoulder. A biopsy specimen form the left arm showed spindle cells with slit-like spaces and extravasated red blood cells. The specimen was positive for CD 34 antigen, and human herpesvirus 8 was detected. We report a case of KS that occurred in a 79-year-old patient on hemodialysis.

In this study, the inspection path which is considered to free collision is generated by offset surface. When the inspection is executed, the consideration of machine dynamic error increases a precision. Dynamic error is measured on CNC machine bed changing of weight work price. Offset surface is safety space about collision. Because the danger of probe-collision is excluded in Offset surface, it is possible to rapid feed of pr obe and reduced inspection time. The Program which is possible to simulate using CAIP and is confirmed through actual experiment.
