Fecal material, also fecal matter, is poo. It is seen in gastrointestinal pathology.
General
- Common.
- Associated with poor bowel preparation.
- People on a low-fibre diet seem to have less of 'em.[1]
- Endoscopists go after anything that is polypoid and that may be nothing more than poo.
Gross
- Soft amorphous material.
- +/-Friable.
Microscopic
Features:
- Plant material:
- Yellow staining chicken wire-like material - may be linear.
- Thick cell walls often without cytoplasm and usually without a nucleus.
- Yellow staining chicken wire-like material - may be linear.
- Meat:
- Eosinophilic honeycomb-like material without nuclei and without inflammation.
- Essentially ischemic skeletal muscle without inflammation.
- Eosinophilic honeycomb-like material without nuclei and without inflammation.
- +/-Microorganisms.
- +/-Inflammatory cells.
DDx:

TRANSVERSE COLON, BIOPSY: - FECAL MATERIAL. - NO DEFINITE COLONIC MUCOSA IDENTIFIED.
Rectum
RECTUM, BIOPSY: - FECAL MATERIAL. - NO DEFINITE RECTAL MUCOSA IDENTIFIED.
