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 tumors Seminoma[1][2]
  • Most common among age of 15-35 years old
  • Does not occur during infancy
Stains positively for: - + Ultrasound:
Embryonal carcinoma[3]
  • Rare type
  • Peak incidence at the age of 30 years old
  • Usually mixed with other types
Early metastasis to: Stains positively for:

May stain positively for :

+ ± Ultrasound:
Yolk sac tumor[4][5]
  • Unilateral
  • Common among Asian
  • Uncommon
Stains positively for:
  • Schiller-Duval bodies (perivascular structures)
  • Hyaline-type globules
+ + Ultrasound:

MRI:

Teratoma[6][7]
  • Unilateral
History of congenital disease such as:
  • May present in both prepubertal and adult men
  • Uncommon in benign ones among prepubertal men

Stains positively for:

- + Ultrasound:
Choriocarcinoma[8][9]
  • Most aggressive type
Early metastasis: Stains positively for: + ± Ultrasound:
Mixed germ cell tumors[10][11]
  • Unilateral
  • Two or more germ cell tumors present as a single mass
  • Depends on underlying components
  • May stain positive based on underlying components
± +

Elevations in:

  • Imaging findings based on underlying components
Carcinoma in situ (intratubular germ cell neoplasia )[12][13][14]
  • Unilateral
  • Bilateral
Common:

Stain positively for:

- -
  • N/A
Elevated for:
  • N/A
Diseases Benign/ Malignant Unilateral/Bilateral History Demography Metastasis Genetics Histopathology Pain Mass Physical exam Lab Findings Imaging
Non- germ cell tumors Leydig cell tumor[15]
  • Unilateral
  • Slowly enlarging painless unilateral mass

Stains positively for:

- +
  • N/A
Ultrasound:
Sertoli cell tumor[16][17][18]
  • Unilateral
  • Bilateral
Stain positively for: - +
  • N/A
Ultrasound:
  • Large cell calcifying variant
  • Hypoechoic
Testicular lymphoma[19][20][21]
  • Unilateral
  • Bilateral ( mostly up to 35% of cases)
  • The most common in men older than 50 years old
Common metastasis to : Stains positively for: - + Ultrasound:
Granulosa cell tumors[22][23]
  • Unilateral

Juvenile type associated with:

Stains positively for: - + Elevated serum: Ultrasound:
