'''Mixed germ cell tumour''' is a [[tumour]] composed on different [[germ cell tumours]]. Most germ cell tumours are mixed. | |||
==General=== | |||
*60% of GCTs are mixed. | |||
Common combinations: | |||
# Teratoma + embryonal carcinoma + endodermal sinus tumour (yolk sac tumour) (TEE). | |||
# Seminoma + embryonal (SE). | |||
# Teratoma + embryonal +(TE). | |||
Memory device: ''TEE'' + all combinations have embryonal carcinoma. | |||
==Microscopic== | |||
Features: | |||
*Depends on components. | |||
Notes: | |||
*If one cannot identify the component... it is probably yolk sac as this has so many different patterns. | |||

===IHC=== | |||
*Beta-hCG +ve - if syncytiotrophoblasts are present. | |||
*AFP +ve - a yolk sac tumour component is present. | |||
*GFAP +ve - if neuroepithelium is present. | |||
