The Peutz-Jeghers syndrome (PJS) is known to be commonly associated with ovarian tumors. However, its association with testicular tumors is uncommon.

To the best of our knowledge, this is the seventh such case being reported in the literature and the presenting manifestation in all seven was gynecomastia.
