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.
- Vaginal bleeding or testicular mass.
- Occasionally thyrotoxicosis.[3]
Note:
- Beta-hCG is negative ~3 weeks after pregnancy.[4]
Epidemiology
- May be preceded by a complete hydatidiform mole.[5]
- More common in the far east.
- More common at extremes of fertile age (teens and 40-50 years).
Gross
- Dark, shaggy, focally hemorrhagic & friable/necrotic-appearing.
- Invasive border.
Microscopic
Features:
- Two cell populations:
- Cytotrophoblasts - key feature.
- Clear cytoplasm.
- Polygonal shaped cells in cords/masses.
- Distinct cell borders.
- Single uniform nucleus.
- 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.
- If chorionic villi are present... it is likely a type of hydatidiform mole.
- The dual cell population may not be evident at first.
- Hemorrhage and marked nuclear pleomorphism are suggestive of the diagnosis.
DDx:
- Invasive hydatidiform mole.
- Placental site trophoblastic tumour (PSTT).
- Mixed germ cell tumour - esp. for testicular and ovarian tumours.

- Beta-hCG +ve.
- Glypican 3 +ve/-ve.
- OCT3 -ve.
- AFP -ve.
Others:
- p63 +ve.[9]
- Ki-67 +ve -- typically >30%.
- CK7 +ve.[10][11]
- MUC-4 +ve.[12]
- CD10 +ve (10 +ve of 10 cases[13]).
- GATA3 +ve.[14]
Notes:
- Beta-hCG is classically said to be produced by syncytiotrophoblasts.[15]
