Gross pathology of hemorrhoids, showing engorged blood vessels.

Fixation

Generally 10% neutral buffered formalin.

Comprehensiveness

On this resource, the following formatting is used for comprehensiveness:

  • Minimal depth
  • (Moderate depth)
  • ((Comprehensive))

Gross processing

Gross report

Example:

((A. Labeled - hemorrhoids. The specimen is received in formalin and consists of)) __ [[number of]] irregular fragment(s) of pink-tan tissue, partially covered by skin and mucosa, measuring __. On sectioning, engorged blood vessels are identified. ((Representative sections are submitted for microscopic examination in one cassette.))

Microscopic evaluation

File:Histopathology of hemorrhoid.jpg
A hemorrhoid; a dilated vein with an organized thrombus, below benign anal epithelium.
  • Have a brief scroll through the tissue to confirm the diagnosis of hemorrhoids (submucosal vessels with dilation, thick walls and congestion, often thrombosed)[1]
  • Look at the epithelium for any anal intraepithelial neoplasia.
Example report:
(Anal tissue, excision:
)
hemorrhoids (and benign anorectal mucosa)
