This is one of the easiest procedures for you to do as a Mohs Tech.When you get an ear or lip wedge, think of it as a slice of pie- with a top crust, a bottom crust, and a filling inside. Because we want to see all the edges contiguous with the remaining ear or lip, we need to look at the edges that form the "pyramid" of the piecie of pie, but we do not need to see the "rounded" edge, since it is in space on the patient.
The drawing on the left represents the "top crust". The Blue area is the filling, and the "bottom crust" is below the filling.
(Drawing on the right) Simply bisect the triangle, ink the upper left crust edge one color and ink the lower left edge a different color. Do the same to the right side upper crust, and the right side lower crust for piece two.
Place the edges you just inked against the slide, and cut the specimen as if it were a normal Mohs layer.
Easy as pie!
