    Area of Science:

    • Gastroenterology
    • Pathology
    • Histology

    Background:

    • Collagenous colitis is a condition characterized by chronic watery diarrhea.
    • It primarily affects middle-aged individuals, predominantly women.
    • Clinical and routine laboratory findings are typically normal.

    Purpose of the Study:

    • To provide a clinical and morphological description of collagenous colitis.
    • To present findings from own cases of the disease.
    • To discuss the histopathological features and clinical course.

    Main Methods:

    • Clinical case review.
    • Colo-rectal biopsy analysis.
    • Histopathological examination of the superficial inter-cryptal lamina propria.
    • Ultrastructural examination of subepithelial fibrils.

    Main Results:

    • Patients present with watery diarrhea and abdominal pain.
    • Colo-rectal biopsies show severe thickening of the subepithelial "collagen table".
    • Ultrastructural analysis reveals bandlike subepithelial collagenous fibrils of types I and III.

    Conclusions:

    • The etiology of collagenous colitis is currently unknown.
    • The condition appears to have a relatively benign clinical course.
    • Management primarily involves symptomatic treatment.
