Overgrowth of normal tissues in a place not normally found is defined as what?

Overgrowth of normal tissues in a place not normally found is defined as a choristoma. A teratoma is a type of tumor composed of multiple types of tissue, while a hamartoma is a benign growth made up of disorganized normal tissue. Neoplasia refers specifically to the abnormal growth of cells that can be either benign or cancerous. Therefore, only choristoma accurately describes overgrowth of normal tissue in an abnormal location.
