Anal canal stenosis is a rare form of anorectal malformation, representing 1%. There are few registered cases and there is little literature on this entity.
It is an entity where the anus presents a stenosis of variable length, is normo-implanted, with a normal appearance, surrounded by an adequate sphincter complex.
The presence of associated cardiovascular, renal, and osteoarticular malformations must be ruled out, and especially the presence of a presacral mass must be evaluated, which may present teratomas, anterior myelomeingocele, among others.
Surgical treatment consists of respecting the sphincter complex through a posterior approach, without dissection of the anterior face of the rectum.
Due to the presence of a normal surrounding sphincter complex, the intestinal functional prognosis of these patients is excellent.
We present the first clinical case in our setting of a patient with stenosis of the anal canal, its form of presentation, surgical treatment and evolution.
