Overview
Testicular cancer must be differentiated from epididymitis, hematocele, hydrocele, spermatocele, granulomatous orchitis, and varicocele.
Differentiating Testicular cancer from other Diseases
Testicular cancer must be differentiated from:
| Diseases | Benign/ Malignant | Unilateral/Bilateral | History | Demography | Metastasis | Genetics | Histopathology | Clinical manifestations | Para-clinical findings | ||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Pain | Mass | Physical examination | |||||||||||
| Lab Findings | Imaging | ||||||||||||
| Germ Cell | Seminoma[1][2] | Malignant | Unilateral | History of cryptorchidism
Excellent prognosis |
|
Late metastasis | Stains positively for ALP, c-KIT, CD30, EMA, and glycogen |

Elevated serum placental ALP (PALP) | Ultrasound:
Homogeneous hypoechoic intratesticular mass Cysts and calcificications are uncommon Inhomogenous feature in larger mass |

| Yolk sac tumor | |||||||||||||
| Teratoma | |||||||||||||
| Choriocarcinoma | |||||||||||||
| Diseases | Benign/ Malignant | Unilateral/Bilateral | History | Demography | Metastasis | Genetics | Pain | Mass | Physical exam | Lab Findings | Imaging | ||
