Sterling silver (an alloy of 92 percent silver, blended with copper and other metals) gives a lustrous appearance to coins, jewelry, and silverware. The fact that pure silver is slightly harder than gold, but still very ductile and malleable, makes it a natural choice for dental fillings.
Ultrasound detected papillary projections in 78% of tumors. Papillary projections were disseminated in 33% of malignant, 20% of borderline, and 0% of benign tumors (p = 0.0049). The mean size of the papillary projections was 9.6, 15.7, and 35.3 mm in benign, borderline, and malignant tumors, respectively (p = 0.0007).
On retrospective analysis of cytology and histopathology slides, 14 cases of papillary lesions were identified [Table 2]. The age group ranged from 27 years to 62 years. The number of cases reported was more in the fifth decade. Seven of the 14 cases were diagnosed as malignant lesions on histopathology [Table 2]. Thirty-six per cent of the cases were found to be true positive, 43% false negative [Figures â[Figures11 and âand2]2] and 21% false positive with a sensitivity of 42% for papillary lesions.
