Grossing separately received oriented margins for a skin ellipse

Grossing separately received oriented margins for a skin ellipse is a relatively common frozen section task.

General

Margin specimens are typically received in pieces with the orientation and an angular location in "o'clock", e.g. "12 o'clock to 3 o'clock".
- Example: Specimen A: 12 o'clock to 3 o'clock, Specimen B: 3 o'clock to 6 o'clock, Specimen C: 6 o'clock to 9 o'clock, Specimen D: 9 o'clock to 12 o'clock.
Ideally, specimens should be inked in a manner that allows them to be identified with the ink colours.

Use four different colours for the interfaces between specimens (where the surgeon cut), e.g. blue = 12 o'clock, green = 6 o'clock, red = 3 o'clock, yellow = 9 o'clock.
Use different colours for the points of bisection - points on opposite sides of the clock can have the same colour, e.g. orange = 1:30 o'clock and 7:30 o'clock, black = 2:30 o'clock and 10:30 o'clock.
- In this schema: if Specimen A: 12 o'clock to 3 o'clock, Specimen B: 3 o'clock to 6 o'clock, Specimen C: 6 o'clock to 9 o'clock, Specimen D: 9 o'clock to 12 o'clock.
  - Specimen A: would have blue and red.
    - 12 to 1:30 would be blue and orange
    - 1:30 to 3:00 would be orange and red.
  - Specimen B: would have red and green.
    - 3 to 4:30 would be red and black.
    - 4:30 to 6 would be black and green.
  - Specimen C: would have green and yellow.
    - 6 to 7:30 would be green and orange.
    - 7:30 to 9 would be orange and yellow.
  - Specimen D: would have yellow and blue.
    - 9 to 10:30 would be yellow and black.
    - 10:30 to 12 would black and blue.
