    Summary
    This summary is machine-generated.

    Primary anorectal melanoma is often diagnosed at advanced stages, presenting with unspecific symptoms like bleeding. Despite aggressive treatment, metastatic disease is common, with a median survival of 14 months.

    Area of Science:

    • Gastroenterology
    • Oncology
    • Surgical Pathology

    Background:

    • Primary anorectal melanoma is a rare and aggressive malignancy.
    • Early diagnosis is challenging due to unspecific clinical presentations.

    Purpose of the Study:

    • To analyze the clinical characteristics, treatment outcomes, and survival rates of patients with primary anorectal melanoma.
    • To review the histopathological features and treatment modalities employed.

    Main Methods:

    • Retrospective analysis of eleven patients diagnosed with primary anorectal melanoma.
    • Review of clinical data, including symptoms, signs, histopathology, treatment received, and follow-up information.

    Main Results:

    • Most patients presented with advanced-stage disease and unspecific symptoms such as bleeding.

  • Metastatic disease developed in all patients after a median of 10 months.
  • Median survival was 14 months following surgical interventions (abdominal perineal resection or local excision).

    • Conclusions:

    • Primary anorectal melanoma has a poor prognosis with a high rate of metastasis.
    • Surgical management, including abdominal perineal resection and local excision, offers limited survival benefits.
    • Further research into novel therapeutic strategies is warranted for this rare cancer.
