Embryonal carcinoma is a relatively uncommon type of nonseminomatous germ cell tumour that occurs in the ovaries and testes.

The clinical features associated with metastasising embryonal carcinoma may include low back pain, dyspnoea, cough, haemoptysis, haematemesis and neurologic abnormalities.

[1] Males with pure embryonal carcinoma tend to have a normal amount of the protein alpha-fetoprotein in the fluid component of their blood.

[citation needed] The gross examination usually shows a two to three centimetre pale grey, poorly defined tumour with associated haemorrhage and necrosis.

[citation needed] In the testis pure embryonal carcinoma is also uncommon, and accounts for approximately ten percent of testicular germ cell tumours.
