Quite compact specimens should not be Lower or bisected while fresh because the correct cutting of fresh specimens is often quite challenging and an irregular Minimize may perhaps cause issues in embedding. Tiny specimens need to be processed either in cassettes by using a high-quality mesh, or in lens paper or simply a “tea bag” so that the specimen can not be dropped in processing, especially over the transit of your cassette with the tissue processor (Figure one).
As the width in the melanoma and depth of invasion are of prognostic importance, the shave biopsy must be processed to show the thickness of the lesion. Good care need to be taken to cut the specimen eccentrically so which the thickest Section of the lesion could be evaluated.
