Proctitis cystica profunda in paraplegics. Report of three cases.

Proctitis cystica profunda is a benign disease of the rectal mucosa that can be mistaken for rectal carcinoma both grossly and microscopically. Symptoms may consist of blood or mucus in the stool, diarrhea, tenesmus, or rectal pain. The disease has never been reported in a paraplegic population before, but the proposed etiology makes this group seem to be at high risk. We report three cases in our paraplegic population and discuss the nature of the disease as well as its treatment.
