unilateral testicular lesions

The differential diagnosis for unilateral testicular lesions is wide-ranging.

Neoplastic

Common

• seminoma (40-50% of testicular malignancies)
• non-seminomatous germ cell tumors:
  • testicular teratoma
  • testicular epidermoid (teratoma with ectodermal elements only)
  • testicular choriocarcinoma
  • testicular embryonal cell carcinoma
  • testicular yolk sac tumor (endodermal sinus tumor)
  • testicular mixed germ cell tumor

Uncommon

• sex cord/stromal tumors (~2% of testicular malignancies):
  • Leydig cell tumor
  • Sertoli cell tumor
• metastasis to testis

Non-neoplastic

• testicular cyst
• tubular ectasia of rete testes (may be bilateral)
• focal orchitis
• focal intratesticular hemorrhage
• ischemia/infarction (e.g. testicular torsion)
  • segmental testicular infarction
• testicular adrenal rest
• focal granulomatous disease:
  • caseating/infective (e.g. tuberculosis)
  • non-caseating (e.g. sarcoidosis)
• supernumerary testes (polyorchidism)
• intratesticular varicocele
• intratesticular arteriovenous malformation
• testicular abscess
