What is teratoma pathology?
(TAYR-uh-TOH-muh) A type of germ cell tumor that may contain several different types of tissue, such as hair, muscle, and bone. Teratomas may be mature or immature, based on how normal the cells look under a microscope.
What is the difference between mature and immature teratoma?
Mature teratomas are benign tumors, which are most often composed of derivatives of two or three germ cell layers. Only in rare cases is the transition into a malignant tumor observed (most often squamous cell carcinoma). In contrast, immature teratomas are malignant ovarian tumors.
What makes a teratoma immature?
An immature teratoma is a teratoma that contains anaplastic immature elements, and is often synonymous with malignant teratoma. A teratoma is a tumor of germ cell origin, containing tissues from more than one germ cell line, It can be ovarian or testicular in its origin. and are almost always benign.
Can a mature teratoma come back?
Mature teratomas are usually benign (not cancerous). But they may grow back after being surgically removed.
Can mature teratoma become malignant?

Why is immature teratoma malignant?

How fast do mature teratomas grow?
Mature cystic teratomas grow slowly at an average rate of 1.8 mm each year, prompting some investigators to advocate nonsurgical management of smaller (<6-cm) tumors (,11).
How do you know if a teratoma is malignant?
They may also order tests, including: Imaging tests, such as X-rays, CT (computed tomography) scans, magnetic resonance imaging (MRI) and ultrasound to determine the size and location of the teratoma. Blood tests to check hormone levels and tumor markers. Biopsy to find out if the teratoma is cancerous or noncancerous.
