Intraoperative diagnosis of seminoma in a man with cryptorchidism and Klinefelter Syndrome planning for m-TESE: A case report.

Undescended testes are more likely to undergo malignant transformation than normally descended testes. We present the case of a 33-year-old male smoker who had been suffering from primary infertility for 4 years. This patient had bilateral undescended testes and a frozen section specimen revealed seminoma. In this report, we discussed how important it is to use a combination of different diagnosis modalities to reach a diagnosis.
