Summary

Malignant melanoma in the anorectal region is rare. Survival varied significantly, with tumor depth inversely correlating with multinucleated cells, but not with survival outcomes.

Area of Science:

  • Oncology
  • Gastroenterology
  • Dermatology

Background:

  • Malignant melanoma of the anorectal region is an uncommon and aggressive malignancy.
  • Limited data exists on its presentation, histology, treatment, and prognostic factors.

Purpose of the Study:

  • To describe the clinical characteristics, treatment, and survival outcomes of patients with anorectal malignant melanoma.
  • To investigate potential correlations between histological findings and survival.

Main Methods:

  • Retrospective case series analysis of eight patients diagnosed with anorectal malignant melanoma.
  • Review of initial presentation, histological data, treatment modalities, and survival duration.

Main Results:

  • Mean survival was 18 months, with one patient surviving 147 months.

  • An inverse correlation was observed between tumor penetration depth and the presence of giant multinucleated cells.
  • No significant correlation was found between survival and specific histological findings or therapeutic regimens.

    • Conclusions:

    • Anorectal malignant melanoma exhibits highly variable survival.
    • Tumor penetration depth and giant multinucleated cells may have a relationship, but do not reliably predict survival.
    • Further research is needed to identify effective therapeutic strategies and prognostic markers.
