Gonadoblastoma is a rare germ cell tumour with sex cord elements.
General
- Associated with abnormal sexual development.
- Often coexist with a dysgerminoma.
- A mixed tumour that consists of (1) primitive germ cells and (2) sex cord elements.
Gross
- +/-Cystic.
Microscopic
Features:[1]
- Immature germ cells resembling Sertoli cells or granulosa cells.[citation needed]
- Sertoli cells = moderate cytoplasm in a trabecular or tubular architecture.
- Granulosa cells = form follicle-like structures.
- May form nests.
- Primitive germ cells resemble those of a dysgerminoma.
- Polygonal cells with a central nucleus, squared-off nuclear membrane and clear cytoplasm.
- +/-Calcification (very common).
- +/-Eosinophilic basement membrane material between the (primitive) germ cells and support cells.[2]
