Sometimes, the fistula follows a subepithelial midline tract opening along the midline perineal raphe, scrotum, or penis. The perineal findings in this kind of defect include a prominent skin tag, below which an instrument can be passed, known as a “bucket-handle” malformation (Figure 43.2), a black (meconium) or white (mucous), ribbon-like, midline structure that represents a subepithelial fistula or a very well-formed anal dimple suggesting the presence of a very low defect. The diagnosis is established by perineal inspection.

The patient had no radiological studies. Since the clinical and social context did not allow an adequate preoperative study, it was decided to perform a surgical exploration under general anesthesia. The patient was placed in lithotomy position, bladder catheterization was performed, and the lesion was approached through a longitudinal incision in the perineal raphe. The presence of an encapsulated tumor with multiple tortuous nerve fascicles inside, with the appearance of a "bag of worms" was observed. Dissection was continued and an adequate cleavage plane between the superficial perineal fascia (Colles’ fascia) and the tumor was observed. An incidental opening of the lesion demonstrated interior nerve bundles.
