The lesions discussed above provide evidence, in addition to that already present in the literature, that seminoma (germinoma), pure or mixed with malignant teratoma, may occur as a primary tumor ...

Roughly 40% of testicular non-seminoma cancers have embryonal carcinoma cells. Choriocarcinoma: These tumors are very rare. They grow rapidly and spread aggressively. Teratoma: Some teratoma ...

Some non seminomas develop from just one type of cell. And some develop from a mixture of cell types. Types of non seminoma tumours include: teratoma (post pubertal type) embryonal carcinoma ...

Nonseminoma. A class of (testicular) GCTs that includes all types other than seminoma, that is, embryonal carcinoma, teratoma, choriocarcinoma and yolk sac tumor (type II GCT). The distinction ...

Histologically, the tumor was a combined seminoma, partially immature teratoma and rhabdomyosarcoma. Biopsy of the right testis revealed no malignancy. AFP and βHCG serum levels were normal.

Non-seminoma tumors tend to metastasize more often ... Most people have widespread metastases when they receive a diagnosis. Testicular teratoma follows an unpredictable pattern.

Seminoma, a type of testicular cancer that predominantly affects young men, is the most common testicular germ cell tumor and is characterized by its similarity to primordial germ cells (PGCs ...

Teratomas are rare tumors that contain different types of tissues such as bone, teeth, muscle, and hair. A teratoma may be cancerous or benign (noncancerous), depending on its structure. Most ...

Non-seminoma is a type of germ-cell testicular cancer. Treatment may include surgery to remove a testicle, lymph node removal, and chemotherapy. Most cases of testicular cancer develop from germ ...
