Is teratoma formed below?

summary

Teratoma comes from ovarian germ cells, one is cystic mature teratoma, which is benign. There is also a malignant teratoma, which contains malignant components. Here to talk about how teratoma is formed.

Is teratoma formed below?

Teratomas originated from potential pluripotent primordial embryo cells, and most of them were benign, but the malignant tendency increased with age. Most of them were found in sacrococcygeal region, mediastinum, retroperitoneum and gonad. Most of them occurred in newborns and infants, especially in women.

In the process of human embryo development, there is a kind of pluripotent cell with pluripotent development potential. Under normal embryonic development, it develops and differentiates into mature cells of each embryo layer. If some pluripotent cells are separated or shed from the whole at different stages of the embryo, resulting in gene mutation and abnormal differentiation, the embryo abnormality may occur.

It is generally believed that this kind of separation or abscission occurs in the early stage of the embryo, which leads to teratogenesis; If it occurs in the later stage of embryo, it forms the abnormal differentiated tissue with endoderm, mesoderm and ectoderm, that is teratoma.

matters needing attention

Teratoma is rare, and the incidence rate is not high. It is scattered in various specialties. The teratoma seen in the Department of general surgery is mainly located in the sacrococcygeal and retroperitoneal, and is benign. Teratoma can occur in ovary, testis, retroperitoneum, anterior mediastinum, sacrococcygeal, skull base, etc. Sacrococcygeal teratomas can be seen in newborns, retroperitoneal teratomas can be seen in newborns, some were found during development, a few were found after malignant transformation.
