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
- 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
Pagetoid dyskeratosis, with pale cells, occurs in most hemorrhoids. Look mainly for nuclear enlargement, which may indicate koilocytes (having raisin-like dark nuclei), extramammary Paget's disease (having prominent nucleoli)[2] or superficial spread of carcinoma or melanoma (look at basal layer and surrounding epidermis.[3]
Microscopic report
- Diagnosis of hemorrhoids
- (Description of thrombi.)
- (Even benign epithelium, with specification of types seen, that is, anoderm, rectal, or anorectal if both are seen.)
- ((Any epidermal hyperplasia and/or Pagetoid dyskeratosis.))
- Example:
(Anal/Rectal/Anorectal tissue, excision:) Hemorrhoids (with organizing thrombi, and benign anoderm/rectal mucosa/anorectal mucosa.) |
