Area of Science:

  • Gastroenterology
  • Oncology
  • Surgical Pathology

Background:

  • Schwannomas are rare tumors originating from Schwann cells of the neural sheath.
  • In the gastrointestinal tract, they are classified under gastrointestinal stromal tumors (GIST).
  • Peripheral nerve sheath tumors constitute 2-6% of GIST, commonly found in the stomach and small intestine.

Observation:

  • Schwannomas of the colon and rectum are exceptionally rare.
  • This report details a unique case of a sigmoid schwannoma.

Findings:

  • The sigmoid schwannoma was successfully treated with radical excision.
  • Literature review underscores the necessity of wide margins due to recurrence and malignant potential.

Implications:
