Author: Mikael Häggström [note 1]

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

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.

Common findings

Microscopic report

  • Diagnosis of hemorrhoids
  • (Even benign epithelium, with specification of types seen, that is, anoderm, rectal, or anorectal if both are seen.)
  • (Description of thrombi.)
  • ((Any epidermal hyperplasia and/or Pagetoid dyskeratosis.))
Example:
(Anal tissue, excision:
)
Hemorrhoids (with organizing thrombi, and benign anorectal mucosa.)
