Treading the unusual path: a rare case of fistula-in-ano extending up to thigh

The perianal region is typically the site of a fistula-in-ano tract's opening, though this is not always the case. Complex fistulas are therefore very difficult to treat and frequently the cause of recurrence. This article describes a unique fistula-in-ano that extended posteriorly to the mid-thigh and was successfully treated with multiple modalities and secondary healing.
