Pathologists recently identified plant seeds mistakenly diagnosed as colon polyps and as causes of appendicitis. These findings highlight how common botanical matter can mimic clinical pathology in the gastrointestinal tract.
Why it matters
Distinguishing dietary seeds from organic tissue is critical for accurate clinical diagnosis, as seeds can be misidentified as polyps or trigger localized inflammation. This awareness prevents unnecessary surgical interventions and informs differential diagnoses for abdominal pain.
A 2021 study found seeds in 2.2% of appendix specimens and 4% of colon resections. Pathologists differentiate these specimens by observing a distinct central embryo and outer seed coat under standard microscopic analysis.
The players
University of Szeged
A research university in Hungary where the authors of the current report are based.
University of Genoa
An Italian research institution where the authors of the 2021 study on gastrointestinal specimens are based.
The details
A seed lodged in the appendix blocks the organ's narrow opening, raising internal pressure and impeding blood flow. This environment fosters bacterial multiplication, resulting in inflammation and ulceration. In the colon, seeds embedded in mucus can physically resemble polyps—small growths of tissue—until confirmed via histology.
Timeline
1816: Fatal peritonitis case linked to cocoa seeds.
1995: Vegetable seed misidentified as a colon polyp.
2017-2020: Gastrointestinal specimen collection for Italian study.
2021: Publication of study on seeds in pathology specimens.
March 10, 2026: Publication of the report in the journal Diagnostics.
The Tech Race
This report updates findings from a 2021 study conducted by researchers at the University of Genoa. It follows a centuries-old documented pattern of botanical matter causing gastrointestinal pathology, dating back to a fatal 1816 case of peritonitis.
These findings underscore the necessity of histological confirmation for gastrointestinal growths rather than relying on initial visual inspection. Patients presenting with abdominal pain should note that even small botanical items can cause acute physical obstructions.
The takeaway
Clinicians must continue to consider botanical seeds in their differential diagnosis for appendicitis and intestinal growths. Practitioners should review the 2021 prevalence data published by researchers at the University of Genoa to improve identification accuracy.
