Leydig cell tumor in identical twin.
A case is presented of an identical twin who had an interstitial cell tumor of the testis removed, and comparison is made with his identical brother over an ensuing six-year period. The dramatic effects of the interstitial cell tumor are clearly shown in the comparison of the two males over this six-year period. To our knowledge this is the only such case in the world literature.
