processor, however I could use some tips or tricks on cutting large fatty skin ellipse specimens. My problem I think, is too small a knife, the specimens are not cutting even and the fat is getting in the way. So any suggestions or links to grossing techniques would be appreciated. Also, any ideas on better cutting utensils for these?<<

First of all, you need to work closely with your dermatopathologist on this
- you shouldn't be expected to get it right all by yourself.

You need to be able to photograph these gross specimens, and insert the photograph in the report.

Gross the specimen as soon as you can, and then fix the slices overnight for processing.

Cut on a good cutting surface in good light with a steady hand.

They make disposable long scalpel blades. These are expensive and a little hard to find, and I've only ever seen them on two pathology services. Here are two resources:

Cellpath - which I've used - excellent knives
