Aberrant goiter may be defined as a thyroid tumor in a location other than that usually occupied by the normal thyroid gland. There are two types, true and false. If the aberrant tissue remains attached to the normally placed thyroid gland and appears to be an outgrowth from it, the term false aberrant goiter may be used to describe it. But if no connection can be traced between the aberrant goiter mass and the normal thyroid gland, or if the latter is entirely lacking, the tumor is properly classed as a true aberrant goiter.
Probably true aberrant goiter develops only from thyroid tissue which has been deposited in the embryo in the development and descent of the thyroid gland. Such a deposit may occur at any point along the course of descent from the foramen caecum to the normal site of the gland or beyond it. It occasionally occurs in
