Pretty small specimens really should not be cut or bisected whilst fresh as the exact cutting of fresh specimens might be very hard and an irregular Lower might induce troubles in embedding. Little specimens needs to be processed possibly in cassettes using a fine mesh, or in lens paper or even a “tea bag” so that the specimen can't be lost in processing, especially in the transit with the cassette with the tissue processor (Figure 1).
