Testicular teratoma

Testicular teratoma is a type of germ cell tumor that develops in the testes, often containing a variety of tissues like hair, muscle, or fat, reflecting cells from multiple fetal layers. It can occur in both children and adults, with the potential to be benign or malignant. The tumor arises from germ cells that have the ability to differentiate into different tissue types. Symptoms may include a painless lump or swelling in the testicle. Diagnosis typically involves physical examination, ultrasound imaging, and blood tests. Treatment usually involves surgical removal of the affected testicle, and prognosis depends on the tumor’s type and stage.
