Prognosis often poor
Treatment surgery and chemotherapy

Choriocarcinoma is a rare aggressive germ cell tumour.

General

  • Aggressive clinical course.
  • Usually a mixed tumour, i.e. pure choriocarcinoma is rare, e.g. dysgerminoma + choriocarcinoma.

Clinical

  • High beta-hCG -- usually > 10,000 IU.
    • Median in one series of testicular choriocarcinoma ~ 200,000 IU.[1]
    • Elevation may be seen in other (non-trophoblastic) tumours.[2]
  • Vaginal bleeding or testicular mass.
  • Occasionally thyrotoxicosis.[3]

Note:

  • Beta-hCG is negative ~3 weeks after pregnancy.[4]

Epidemiology

Gross

  • Dark, shaggy, focally hemorrhagic & friable/necrotic-appearing.
  • Invasive border.

Microscopic

Features:

  • Two cell populations:
  1. Cytotrophoblasts - key feature.
    • Clear cytoplasm.
    • Polygonal shaped cells in cords/masses.
    • Distinct cell borders.
    • Single uniform nucleus.
  2. Syncytiotrophoblasts - may be absent.[6]
    • Large + many irreg. or lobular hyperchromatic nuclei.
    • Eosinophilic vacuolated cytoplasm (contains hCG).
  • +/-Hemorrhage - classically in the centre of the lesion.
  • +/-Necrosis.

Notes:

  • No chorionic villi should be present.
  • The dual cell population may not be evident at first.
    • Hemorrhage and marked nuclear pleomorphism are suggestive of the diagnosis.

ISUP consensus paper by Ulbright et al.:[8]

  • Beta-hCG +ve.
  • Glypican 3 +ve/-ve.
  • OCT3 -ve.
  • AFP -ve.

Others:

Notes:

  • Beta-hCG is classically said to be produced by syncytiotrophoblasts.[15]
    • Cytotrophoblasts also produce some[15][16] - usually no staining.
