Summary

This report details a rare retrorectal lesion, identifying low-grade endometrioid adenocarcinoma within a tailgut cyst. This suggests malignant transformation in pluripotent cells of a tailgut lesion.

Area of Science:

  • Oncology
  • Pathology
  • Surgical Gastroenterology

Background:

  • Retrorectal lesions are uncommon and present diagnostic challenges.
  • Tailgut cysts are congenital remnants that can rarely undergo malignant transformation.

Observation:

  • A unique case of a retrorectal lesion was analyzed.
  • The lesion exhibited characteristics of low-grade endometrioid adenocarcinoma.

Findings:

  • The study identified malignant transformation within a long-standing retrorectal tailgut cyst.
  • This represents the first reported instance of endometrioid adenocarcinoma arising in a retrorectal tailgut cyst.

Implications:

  • This case expands the understanding of rare retrorectal pathologies.
  • It highlights the potential for malignant changes in tailgut cysts, necessitating careful pathological evaluation.
