A teratoma is a tumor made up of several types of tissue, such as hair, muscle, teeth, or bone. [4] Teratomata typically form in the tailbone (where it is known as a sacrococcygeal teratoma), ovary, or testicle. [4]

2023年12月8日 · A teratoma is a rare type of tumor that can grow on your tailbone, ovaries, or testicles or in other places on your body. They form from germ cells, which can develop into any type of cell in the...

2023年9月19日 · A teratoma is a rare type of germ cell tumor that may contain immature or fully formed tissue, including teeth, hair, bone and muscle. Most teratomas are benign (noncancerous) but they can be malignant (cancerous). Treatment involves surgical removal. Cancerous teratomas may require chemotherapy, radiation therapy or other cancer treatments.

2018年9月14日 · A teratoma is a rare type of tumor that can contain fully developed tissues and organs, including hair, teeth, muscle, and bone. They’re most common in the tailbone, ovaries, and testicles.

2024年4月24日 · Teratomas are germ cell tumors that arise from ectopic pluripotent stem cells that fail to migrate from the yolk sac endoderm to the urogenital ridge during embryogenesis. By definition, they contain elements from all three embryological layers: endoderm, mesoderm and ectoderm although frequently, elements from only two layers are evident.

A teratoma is a relatively rare type of tumor. Your cells are constantly multiplying to make new cells. When this process goes awry and new cells are created unnecessarily, or old cells stay alive instead of dying, they can cluster together and form a tumor.

2023年3月3日 · A teratoma is a rare type of germ cell tumor that may or may not be malignant. Learn about the different types and how doctors diagnose and treat them.

2025年3月2日 · Teratoma, rare tumor that originates from remnants of germ cells (the precursors of eggs and sperm) or germ layers (cell layers formed in early embryonic development)—namely, the ectoderm, endoderm, and mesoderm.

2025年1月6日 · What is a teratoma? A teratoma is a type of germ cell tumor that contains different types of tissues, including hair, teeth, eyes, bone, muscle, and neurons.

Teratomas are a type of tumor that can contain tissues from multiple germ cell layers. There are several types of teratomas, including mature teratomas composed of well-differentiated tissues like skin, hair, and teeth, as well as immature teratomas containing less differentiated or embryonic tissues.
