Abstract:
A method for processing tissue specimens comprising the steps of:(a) obtaining a cylindrical tissue specimen having a longitudinal axis and an outside diameter;(b) positioning the cylindrical tissue specimen inside a cylindrical canister having an inside diameter slightly larger than the outside diameter of the cylindrical tissue specimen, said cylindrical canister permitting transmission of a tissue fixative to the cylindrical tissue specimen to allow fixation thereof;(c) immersing the cylindrical canister with the cylindrical tissue specimen positioned therein in a tissue fixative until the cylindrical tissue specimen is fixed;(d) embedding the fixed cylindrical tissue specimen;(e) cross-section microtome slicing the embedded, fixed cylindrical tissue specimen in a plurality of planar slices that are perpendicular to the longitudinal axis of the fixed cylindrical tissue specimen;(f) mounting the specimen tissue slices on slides;(g) evaluating the slides to determine the presence of any lesion in the specimen tissue slices and, if present, selecting the slide showing the periphery of the lesion nearest to the cut edge of the specimen; and,(h) measuring the shortest distance between the periphery of the lesion and the cut edge of the specimen on said selected slide.
