    Area of Science:

    • Gastroenterology
    • Histopathology
    • Colorectal Medicine

    Background:

    • Chronic watery diarrhea can present diagnostic challenges.
    • Collagenous colitis is a recently described condition characterized by subepithelial collagen deposition in the colon.
    • Accurate diagnosis is crucial for appropriate patient management.

    Observation:

    • Repeated colonic and rectal biopsies were performed on a 47-year-old female patient.
    • The biopsies revealed a significant finding: an approximately 50 micrometer thick subepithelial band-like collagenous deposit.
    • This deposit was consistently observed across multiple biopsy samples.

    Findings:

    • The histopathological examination of the biopsies was key to the diagnosis.
    • The presence of the characteristic subepithelial collagenous layer strongly indicated collagenous colitis.

    Related Experiment Videos

  • The clinical presentation of chronic watery diarrhea correlated with the observed pathological findings.

    • Implications:

    • This case highlights the importance of considering collagenous colitis in patients with unexplained chronic watery diarrhea.
    • Accurate histopathological assessment of colonic biopsies is essential for diagnosing this condition.
    • Understanding the characteristic features of collagenous colitis aids in its recognition and management.
