What is a thyroglossal cyst infection?

Embryology: When your body was forming in the womb, your tongue (glossus) and thyroid gland arose from the same primordial tissues. As the tissues that would become your thyroid gland moved down in to your neck, they left remnants of those precursor tissues. Later in life, they became cystic, became infected with oral (usually) bacteria and became abscessed. Speak to your doctor about its removal.
