    Triple ectopic thyroid associated with normally located pretracheal thyroid gland: A rare entity
    (Edorium Journals, 2016) Mchonde, Gabriel J.; Nondoli, Hortensia G.; Hirakawa, Masato
    Triple ectopic thyroid tissues associated with a normally located thyroid is a rare encountered anomaly among thyroid dysgenesis. Case Report: Herein, we present a case observed during a routine dissection on a 88-year-old embalmed female cadaver who had a normally located pretracheal thyroid gland coexisted with three independent inferiorly located thyroid tissue masses extended into the superior mediastinum displacing the aortic arch and associated major vessels. Thyroid dysgenesis can be genetic and inheritable due to involvement of mutations on regulatory genes required for early embryonic development of the thyroid gland. More information on these rare anatomical variations could benefit physicians, surgeons and radiologists on differential diagnosis and management strategies during their routine procedures.
