By Mayo Clinic staffSolitary rectal ulcer syndrome is a condition in which typically a single ulcer occurs in the rectum, producing signs, such as rectal bleeding with straining, when you pass bowel movements.
In some cases, however, solitary rectal ulcer syndrome can result in more than one lesion or in lesions that aren't ulcers, such as polyp-like masses. This rare and poorly understood disorder occurs in people with chronic constipation and may be due to injury to the rectum. Solitary rectal ulcer syndrome can be recurrent.
Treatments for solitary rectal ulcer syndrome range from changing your diet and fluid intake in mild cases to medications or surgery.
