Tissue selection from suspected malignant skin lesions, by lesion size:[1][notes 1]
<4 mm 4 - 8 mm 9 - 15 mm

In table above, each top image shows recommended lines for cutting out slices to be submitted for further processing. Bottom image shows which side of the slice that should be put to microtomy. Dashed lines here mean that either side could be used. Further information: Gross processing of skin excisions
