Solitary ganglioneuroma of the rectum: report of two cases.

Two cases of solitary rectal ganglioneuromas are reported, one in a patient with several previously resected colorectal adenomas, the other in a patient with no known predisposing pathology. No prior reports of cases of solitary rectal ganglioneuroma have been published as far as is known, and the origin of similar lesions which have been reported at other sites in the gastrointestinal tract is a subject for speculation.
