Describes the frequent appearance of two or more malformations with an unknown shared cause. In the event of a symmetrical double malformation, both fetuses have a complete set of organs, whereas, with an asymmetrical malformation, the uneven allocation leads to allocation to the more developed autosite with the less developed parasite, the development of which can be restricted to a tumor-like attachment in the form of a teratoma at the lowest level.
