Non-seminomatous germ cell tumour

Case contributed by Dr Andrew Ryan


Testis mass. Negative serum markers

Patient Data

Age: 30 years old
Gender: Male

Orchidectomy specimen

Left testis - Much of the testis is replaced a relatively circumscribed, solid to focally cystic, pale tan tumour. The lesion is macroscopically confined to the testis. There is a cuff of residual normal tan testicular parenchyma

Case Discussion

This is an example of a non-seminomatous germ cell tumour (NSGCT) and contained areas of embryonal carcinoma and immature teratoma.

In contrast to the solid, homogenous pale appearance of seminoma, mixed germ cell tumours will more often have a mixed solid and cystic appearance and areas of congestion and haemorrhage (the latter sometimes relating to areas of choriocarcinoma).
