Schwannoma in Ascending Colon: A Rare Cause of Abdominal Pain


Schwannoma, (also called neurilemoma, neurinoma) is a benign tumor originating from nerve sheath of the Schwann cells. They rarely occur in gastrointestinal tract. We report a rare case of colonic schwannoma in a 38-year-old woman presenting with worsening right-sided pelvic pain, discovered after laparoscopic right-colon resection performed after the detection of a atypical polypoid mass in the ascending colon. Diagnosis is confirmed by immunohistochemical staining panel.
