A perspex grid for localization of non-palpable mammographic lesions in breast biopsies.

The examination of excised, non-palpable mammographic lesions in breast biopsies is a recognized problem for the pathologist. There may be difficulties in identifying the lesion macroscopically and in subsequent sampling. This paper describes a simple method for resolving these problems. The breast biopsy is attached to a perspex grid and then radiographed. Use of the grid co-ordinates assists appropriate sampling of the specimen. Advantages over previously described methods are discussed.
