During and after puberty, all teratomas are regarded as malignant because even mature teratomas (composed of entirely mature histologic elements) can metastasize to retroperitoneal lymph nodes or to other systems. Reported rates of metastasis vary from 29-76%.

Where do testicular Tumours metastasize to?

The “M” in the TNM system describes whether the cancer has spread to other parts of the body, called distant metastasis. When testicular cancer spreads, it most commonly spreads to the lung and the lymph nodes of the chest, pelvis, and the base of the neck. More advanced stages may have spread to the liver and bones.

Is testicular teratoma cancerous?

What is testicular teratoma?

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.

Can a mature teratoma metastasis?

Growing teratoma syndrome (GTS) is a metastatic form of a mature teratoma and involves the clinical and radiological enlargement of metastases during or after chemotherapy for malignant germ cell tumors [1].

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.
