cystic teratoma การใช้

Cystic teratomas usually are grade 0 and, conversely, grade 0 teratomas usually are cystic.
A dermoid cyst is a mature cystic teratoma containing hair ( sometimes very abundant ) and other structures characteristic of normal skin and other tissues derived from the ectoderm.
As dermoid cysts grow slowly and contain mature tissue, this type of cystic teratoma is nearly always malignant, a squamous cell carcinoma usually develops in adults, while infants and children usually present with an endodermal sinus tumor.
Teratomas are also classified by their content : a solid teratoma contains only tissues ( perhaps including more complex structures ); a cystic teratoma contains only pockets of fluid or semi-fluid such as cerebrospinal fluid, sebum, or fat; a mixed teratoma contains both solid and cystic parts.
