This is an enlargement of the thyroid gland, an organ that if it performs any functions at all, does so only in foetal life. It generally commences by moderate increase of the gland, or thickening of the neck, and advances gradually until a portion or the whole gland becomes enormously swollen. It causes dyspnoea, and sometimes obstructs circulation to the brain, when the tumor acquires considerable magnitude. It is more common to females than males, and generally occurs before puberty. The species of idiocy sometimes associated with goitre is called Cretinism.
