What is embryonal carcinoma with teratoma?
Embryonal carcinoma is a rare type of nonseminomatous germ cell tumor occurring in the mediastinum of young males, as either a pure or a mixed form. It is often associated with teratoma (i.e. teratocarcinoma), choriocarcinoma, or seminoma. The serum alpha-fetoprotein level is elevated in almost all cases.
What is a teratoma in the testicle?
Testicular teratoma is a neoplasm derived from germ cells of the testicle. It can display diverse biological behavior with an aggressive nature at times, and therefore it must be promptly diagnosed and treated.
Is embryonal carcinoma aggressive?
An embryonal carcinoma is an aggressive tumor due to its tendency to early hematogenous spread emphasizing the need for early detection and treatment.
What is embryonal carcinoma?
Embryonal carcinoma is a germ cell tumor characterized by primitive epithelial cells with marked pleomorphism and various histologic patterns. It may present in pure form but often is part of a mixed germ cell tumor.
Is teratoma benign or malignant?
Mature teratomas are the most common type of ovarian germ cell tumour. They are non cancerous (benign). Mature teratoma is also often called a dermoid cyst.
What makes a teratoma malignant?
A malignant teratoma is a type of cancer consisting of cysts that contain one or more of the three primary embryonic germ layers ectoderm, mesoderm, and endoderm. Because malignant teratomas have usually spread by the time of diagnosis, systemic chemotherapy is needed.
Is testicular teratoma aggressive?
Testicular teratoma, unlike ovarian teratoma, is often aggressive in its biological behavior, and often exists as part of testicular mixed germ cell tumors.
Is testicular teratoma curable?
Testicular cancer overall has become one of the most treatable solid organ malignancies and is associated with a fairly good prognosis. There is a 5 year survival rates for testicular teratoma for approximately 90% in patients with good prognostic features.

Why is it called embryonal carcinoma?
Yolk sac carcinoma: These tumors are so named because their cells look like the yolk sac of an early human embryo. Other names for this cancer include yolk sac tumor, endodermal sinus tumor, infantile embryonal carcinoma, or orchidoblastoma.
Is embryonal carcinoma painful?
However, it is present as a component of almost ninety percent of mixed nonseminomatous germ cell tumours. The average age at diagnosis is 31 years, and typically presents as a testicular lump which may be painful.
Is a teratoma a fetus?
There’s a rare type of teratoma known as fetus in fetu, or fetus within a fetus. This type of teratoma looks like a small fetus without an amniotic sac or placenta, and it occurs in about 1 in 500,000 people.
