Here, we report a rare case of migration of a foreign body has occurred from loin to scrotum. A 35-year-old male patient presented with right sided scrotal mass, on exploration it was found to be a metallic bullet. The patient had a history of gunshot injury in his loin 8 years back and was treated conservatively that time. The probable explanation to this mysterious incident may be that, the bullet might have entered the peritoneal cavity through the loin, but did not cause any extensive damage, so the patient well responded to the initial conservative management. With time, due to changes in abdominal pressure or may be due to gravitational force, it had migrated to the dependent scrotum through the patent processus vaginalis. So, this case signifies that a foreign body can migrate through the body planes and get settled far from the primary place.
