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):
- metastasis to testis
Non-neoplastic
- testicular cyst
- tubular ectasia of rete testes (may be bilateral)
- focal orchitis
- intratesticular hematoma
- ischemia/infarction (e.g. testicular torsion)
- 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
