mature teratoma

(redirected from cystic teratoma)

mature teratoma

A tumour that maintains an orderly arrangement, with well-differentiated ectodermal and mesodermal tissues surrounding endodermal components. Most mature teratomas have a cystic cavity lined by epithelial cells, and are typically filled with sebaceous secretions and hair. While they are usually benign, malignant degeneration in the form of squamous cell carcinoma are well described.
