[Melanosis coli(author's transl)].

F H Franken, B Wiechers

    Leber, Magen, Darm
    |December 1, 1975
    PubMed
    Summary

    Melanosis coli, a sign of laxative abuse, involves pigment deposits in the colon. Recognizing this condition during rectoscopy is crucial for diagnosing unexplained abdominal complaints.

    Area of Science:

    • Gastroenterology
    • Pathology

    Context:

    • Melanosis coli is a condition characterized by pigment deposition in the colonic mucosa.
    • It is strongly associated with the long-term use of anthranoid laxatives.
    • Patients often deny or conceal laxative abuse, complicating diagnosis.

    Purpose:

    • To highlight the diagnostic significance of melanosis coli.
    • To emphasize the link between melanosis coli and chronic laxative abuse.
    • To illustrate how recognizing melanosis coli can explain unexplained abdominal symptoms.

    Summary:

    • Melanosis coli results from melanin or lipofuscin pigment accumulation in the colon lining.
    • Diagnosis is achievable through morphological and histological examination during rectoscopy.
    • Despite being easily diagnosable, the condition is frequently overlooked.

    Impact:

    • Increased awareness of melanosis coli can aid in diagnosing chronic laxative abuse.
    • Identifying melanosis coli may help elucidate the cause of otherwise unexplained abdominal complaints.
    • This condition serves as a visible marker for long-term laxative misuse.
