Missing vas

In the case described by Khan and Novell1—a man with a missing vas in whom the ipsilateral kidney was absent but the ipsilateral testicle was present—the primary cause is presumed to be failure of development of the mesonephric (Wolffian) duct. Many years ago I saw failure of development of one of the other pair of genital ducts, the paramesonephric (Müllerian), in a woman2. In this instance, the left Fallopian tube was half an inch (1 cm) long and ended blindly. There was no left broad ligament, left ovary or left kidney and no left ureter was seen. The left round ligament appeared normal.
