Calcification in augmentation mammoplasty.

Twenty-five cases of augmentation mammoplasty from among 1,600 routine mammograms were divided into paraffin and silicon compound groups. Calcification occurred in 11 cases and was seen in 75% of the paraffin group and 29% of the silicone group. The calcifications in the paraffin group were small, annular, and too numerous to be counted. They were diffusely distributed and tended to involve the lymph nodes. The calcifications in the silicone group were large, egg-shaped, localized, and fewer in number. Lymphadenopathy was rare. The two groups also differed in time elapsed between mammoplasty and mammography.
