Notes:
Ten years ago, a 17-year-old high school student noticed a small growth in the prepuce near the free edge; this elevation (Fig. 1) began to grow progressively until it was 0.5 cm long and 0.3 cm wide (Fig. 2). The base of this tumor was not pediculated, it was lighter in color than the skin around it, and its consistency was half soft.The upper part of the tumor was covered completely by the skin of the penis. The patient stated that he had never felt pain and that the tumor had not changed in size. He felt a slight sensation of tension in this area only when he had not urinated for many hours and his bladder was full. He also had this sensation in the normal penis.A careful examination showed that the testes, scrotum, and penis were normal, without hypospadias. On rectal examination, the prostate and seminal vesical were found to be normal. Neither the anus nor the rectum showed any change.Secretory urographic studies showed two normal kidneys that were somewhat descended and rotated. Neither the lumbosacral region of the spinal column nor the pubis was abnormal. The diphallus was extirpated while the patient was under local anesthesia, and we noticed that there was no connection between the tumor (diphallus) and the normal urethra. Histologic Examination: The surgical extirpation was divided into several 5-mm portions. On macroscopic examination, it had a cystic appearance, with creamy contents.The first portions revealed the presence of a pavement and horny (keratinous) epithelium (Fig 3), with a dilated duct beneath It; this duct was covered by transitional mucus, similar to that covering the normal urethra (Fig. 4).In the last pieces cut, at low and high magnifications, a urethral cavity was seen that was covered by a pavement epithelium; under this epithelium, numerous groups of erectile fibers were found (Fig. 5).
