| Fecal material | |
|---|---|
| Diagnosis in short | |
 A food particle and a tubular adenoma. H&E stain. | |
|
| |
| LM | plant matter - has cell walls, meat - skeletal muscle without nuclei, microorganisms (bacilli, cocci), +/-colorectal mucosa |
| LM DDx | necrosis |
| Gross | soft material, amorphous, friable |
| Site | cecum, colon, rectum |
|
| |
| Clinical history | poor bowel preparation |
| Prevalence | relatively common |
| Endoscopy | polypoid lesion |
| Prognosis | benign |
| Clin. DDx | gastrointestinal polyp |
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.
DDx:
- Colonic cast - membranous appearance; described as airbladder of fish-like.[2]
- Arises in colonic ischemia[3] - typically post-AAA repair or after colorectal surgery.[4]
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:
- Essentially ischemic skeletal muscle without inflammation.
- Eosinophilic material without nuclei and without inflammation.
- Honeycomb-like when fibres seen in cross-section.
- Eosinophilic material without nuclei and without inflammation.
- Essentially ischemic skeletal muscle without inflammation.
- +/-Microorganisms.
- +/-Inflammatory cells.
DDx:
Images
Anucleate striated muscle - intermed. mag.
Anucleate striated muscle - high mag.
Anucleate striated muscle - high mag.
Anucleate striated muscle - extremely high mag.
TA and plant material - intermed. mag.
TA and plant material - high mag.
Plant material - very high mag.
Sign out
- Often ignored if colorectal mucosa is present.
TRANSVERSE COLON, BIOPSY: - FECAL MATERIAL. - NO DEFINITE COLONIC MUCOSA IDENTIFIED.
Alternate
ASCENDING COLON ("POLYP"), REMOVAL:
- CONSISTENT WITH PARTIALLY DIGESTED FOOD.
- NO DEFINITE COLONIC MUCOSA IDENTIFIED.
Micro
The sections show a fragment of striated muscle without nuclei and without inflammation, with scant microorganisms. No colorectal mucosa is identified.
Rectum
RECTUM, BIOPSY: - FECAL MATERIAL. - NO DEFINITE RECTAL MUCOSA IDENTIFIED.
