For an intact polyp, identify and ink the resection margin or stalk if identifiable.
Photograph any specimen if >5cm in the greatest diameter.
Allow the specimen to fix in formalin (or Bouin’s fixative if available) for several hours.
Measure the polyp head in three dimensions and measure the length and diameter of the stalk if present.
Describe the external surface of the polyp (sessile vs. pedunculated, color, texture of surface mucosa, ulceration).
For polyps with no stalk or a stalk less than 1 cm in length, cut in half longitudinally so that each half includes both polyp and stalk with resection margin. Continue to serially section at 3 mm intervals in the same plane of sectioning, if necessary.
For polyps with a stalk 1 cm or more in length, take a cross section of the base. Then cut the polyp and stalk longitudinally so that each half includes both polyp and stalk. Continue to serially section the head at 3 mm intervals in the same plane of sectioning, if necessary.
Describe the cut surface of the head and the stalk (color, solid vs. cystic) , examine for any evidence of invasion.
For polyps in multiple pieces, serially section tissue and examine for hard white areas or necrosis.
Received without fixative/in formalin, labeled with the patient’s name, medical record number, and “ _____”, is a _____ (color, surface appearance) sessile/pedunculated polyp/polypoid soft tissue fragment. The stalk measures __ cm in diameter and __ cm in length and the head measures __ x __ x __ cm. The resection margin is inked black/blue. The specimen is serially sectioned and entirely submitted as follows:
#__ - #__ = polyp with stalk and inked resection margin, __ pieces in each.
#__ & #__ = remainder of polyp head, __ pieces in each.
