Acquired tufted angioma is a benign, slowly progressive angioma with a typical histological pattern that was first described by Wilson-Jones in 1976. We report a case of acquired tufted angioma in a 19 year old female who had erythematous papules and plaques on the right thigh.

Recently, due to the tremendous growth of media technology, demands of the aspheric glass lens which is a high-performance and miniaturized increase gradually. Generally, the aspheric glass lens is manufactured by GMP(Glass Molding Press) method using WC(tungsten carbide) mold core. In this study, the shrinkage which was occurred by GMP process was analyzed and applied it to compensate the aspheric glass lens. The compensated lens was satisfied that can be applied to the actual specifications
