Perineal groove, or how something small can become a big problem

Here is presented the case of a 2-years-old asian girl recently arrived from China after her adoption by a Spanish family. In her first clinical examination it is seen a painless injury in the perineum, from anus to fourchette, compatible with a perineal groove. This is a small benign malformation whose existence should be known, because ignorance can lead to confusion, among other possibilities, sexual abuse, with all the consequences this has.
