MASQUERADING AS RECTAL POLYP: CLINICAL SIGNIFICANCE AND LITERATURE REVIEW
Authored by Sarfaraz Jasdanwala
Ganglioneuroma (GN) of colon is a rare tumor of
gastrointestinal (GI) tract. GNs of GI tract are usually confined to colon
particularly rectum. GNs are usually found incidentally but can be associated
with MEN IIb, von Recklinghausen’s neurofibromatosis or Cowden syndrome. A
21-year-old female with past medical history of bulimia, bipolar disorder and
hypothyroidism, who presented with complaints of hematemesis and hematochezia.
Her physical exam was unremarkable. She subsequently underwent an EGD and
colonoscopy for further evaluation. EGD reveled mild gastritis. Colonoscopy
revealed two 5 mm sessile polyps in the sigmoid colon and the rectum. Biopsy of
the rectal polyp showed ganglioneuroma. This represents a case of polypoid
ganglioneuromatosis. These polyps are endoscopically small sessile or
pedunculated polyp indistinguishable from hyperplastic and adenomatous polyps.
They are not associated with increased risk of colon cancer and don’t require
additional screening. On the other hand, ganglioneuromatous polyposis and
diffuse ganglioneuromatosis can be associated with increased risk of colon and
other cancers, and may require further work up.
