The Case of Huge Pure Lipoma of the Spermatic Cord Misdiagnosed as Inguinal Hernia.

Clinically, pure spermatic-cord lipoma has not been recognized as a disease entity but regarded as an incidental finding at the time of hernia repair, because it presents groin symptoms and clinical findings indistinguishable from those of inguinal hernia. We report the successful treatment of case of huge pure spermatic-cord lipoma originally misdiagnosed as inguinal hernia. The patients had tumor excision without orchiectomy. Symptoms improved without any complication. In patients with inguinal hernia symptoms, pure spermatic-cord lipoma should be recognized as a significant clinical entity, and differential diagnosis should be achieved using ultrasonography and computed tomography to avoid unnecessary hernia repair.
