Teratoid medulloepithelioma can present different heteroplasia grades substitution of normal tissue for abnormal tissue, or normal tissue found outside of its habitual location. It can be found in the following tissues: hyaline cartilage, rhabdomyoblasts germ cells which originate muscle tissue, glial tissue similar to cerebral tissue and non-differentiated mesenchymal cells. Also known as teratoneuron Figures 1 to 3 2.
El medulo epitelioma teratoide presenta grados de heteroplasia sustitución de tejido normal por tejido anormal, o tejido normal pero fuera de su lugar habitual, hallándose tejidos como cartílago hialino, rabdomioblastos células germinales que dan origen al tejido muscular, tejido neuroglial similar al cerebral y células mesenquimatosas indiferenciadas, conocido también como teratoneuroma Figuras 1 a 3.
