Two primary seminomas in a patient with polyorchidism.

We report the clinical, radiographic and pathological findings of polyorchidism and a right-sided abdominal seminoma found in a 28-year-old man who presented with cryptorchidism in childhood and who later underwent an orchiectomy for a left-sided seminoma. Pathological analysis of the abdominal tumour revealed the existence of a classic seminoma bordered by a rim of non-tumour tissue and remnants of epididymis. We propose that patients who present with cryptorchidism be assessed for polyorchidism as this might be the source of additional primary tumours.
