Pathology
Germ Cell Tumors (95%) Non–Germ Cell Tumors (5%)
  1. Seminoma

    1. Classic

    2. Spermatocytic

  2. Nonseminoma

    1. Embryonal carcinoma

    2. Teratoma

      1. Teratoma (Mature or Immature)

      2. Teratoma with malignant transformation

    3. Choriocarcinoma

    4. Yolk sac (endodermal sinus) tumor

Note: Most common nonseminoma histology is a mixture of ≥2 histologies. Pure teratoma represents a fully malignant GCT

  1. Sex cord-stromal (gonadal stromal) tumors

    1. Leydig cell

    2. Sertoli cell tumor

    3. Granulosa cell

  2. Both germ cell and gonadal stromal elements

    1. Gonadoblastoma

  3. Adnexal and paratesticular tumors

    1. Mesothelioma

    2. Carcinoma of rete testis

  4. Miscellaneous neoplasms

    1. Carcinoid

    2. Lymphoma

    3. Sarcoma

    4. Other

Work-up
Suspicious Testicular Mass (by History or Exam) Confirmed Testicular Mass (by Ultrasound) Seminoma or Nonseminoma (S/P Orchiectomy)
History and physical STM if not yet done STM
AFP, hCG, and LDH (serum tumor markers [STM]) CBC, complete metabolic profile CBC, complete metabolic profile
CBC, complete metabolic profile CT A/P + either CXR or CT chest CT C/A/P if >4 weeks since prior
Scrotal ultrasound Bone scan or MRI Brain, only if clinically indicated

Bone scan or MRI Brain, only if clinically indicated

Discussion of sperm banking if further treatment (surgery, chemotherapy, or XRT) is required

Staging

Staging
T: Primary Tumor Staging
pTx Primary tumor cannot be assessed
pT0 No evidence of primary tumor
pTis Intratubular germ cell neoplasia (testicular intraepithelial neoplasia)
pT1 Tumor limited to testis and epididymis without lymphovascular invasion (LVI); tumor may invade tunica albuginea but not tunica vaginalis
pT2 Tumor limited to the testis and epididymis with LVI or tumor extending through the tunica albuginea with involvement of the tunica vaginalis
pT3 Tumor invades the spermatic cord with or without LVI
pT4 Tumor ...
