Embryonal tumor is a mass of rapidly growing cells. It is believed that it begins in embryonic (fetal) tissue.^[1] Embryonal tumors may be benign or malignant, and include neuroblastomas and Wilms tumors. Also called embryoma. Embryomas have been defined as: "Adult neoplasms expressing one or more embryo-exclusive genes", in: "Embryoma Gene Networks", http://www.embryomas.net

Embryomas can appear in the lungs.^[2]

It is not a precise term, and it is not commonly used in modern medical literature. Embryomas have been defined as: "Adult neoplasms expressing one or more embryo-exclusive genes".
