[Perineal groove in pediatric gynecology: a report of 2 cases]
Introduction:
the perineal groove is a very uncommon anorectal anomaly. It is the result of an unknown embryology anomaly. The perineal groove is a wet sulcus extending from de fourchette to the anus. It is a benign pathology and tends to resolve spontaneously.
Objective:
We report two cases of girls diagnosed with perineal groove and their follow up.
Cases Reports:
The first case is an 18 days old baby girl, that during her first clinical examination there was found a painless lineal lesion in the perineum from the fourchette to the anus, which created a big anxiety in her family. She was cared at the Pediatric Gynecology Unit, with local lubrication, doing well with the epithelization of it. The second case is an 8 year-old girl who consulted because, when being a child, she was diagnosed with a perineal lesion, but she didn't receive any special treatment and now she feels some aches in the perineum.
Conclusions:
The perineal groove is a benign entity pretty unknown by general practitioners or pediatricians. It is important to be up to date with this condition to avoid alarming misinterpretations.
