  • Abstract
  • Look Inside

We report a rare case of bilateral synchronous testicular tumors, right seminoma and left epidermoid cyst. A 49-year-old man was admitted to our hospital for the evalua-tion and treatment of right testicular tumor. MRI revealed the left cystic mass associated with right solid mass in the testicles. Initially high inguinal orchiectomy was performed. Pathological diagnosis showed seminoma with intratubular malignant germ cell, so the operation to the left cystic mass was performed under the suspicion of malignancy. Pathological study of frozen section revealed epidermoid cyst, therefore enucleation of the tumor was performed.
