What does a small white lump in outer fold of rectum indicate?
Looks to be a benign mass.
Thanks for your query.
I hope you mean the anal canal or anus in place of outer fold of rectum.
A small white lump in in the folds of the anus/ rectum, which is not causing any pain or bleeding and not grown in the last three months is most probably just a cyst or a lump / papiloma related to the skin.
I do not think there is anything to worry about. You can wait and watch, have regular note where there is any change in size, pain, redness, itching or bleeding. If ther is a change you can certainly visit a Doctor and get this checked by a Surgical Gastro ( GI) Specialist.
