“…In our case, all tissue samples were negative for any malignancy. There are few reported cases of dual or triple ectopic thyroids [1, 16–24]. Our case was not detected on preoperative workup including CT scan, ultrasound, and thyroid scintigraphy.…”

Introduction An ectopic anomalous accessory thyroid is extremely rare. We present two related case reports. Case A 43-year-old morbidly obese female presented with a palpable left thyroid mass. Initial impression after preoperative workup was a diffuse bilateral multinodular goiter with a left nodule suspicious for malignancy. She underwent a total thyroidectomy. On further palpation after initial excision, two masses on the left neck area were noted, dissected, and excised. In the second case, a 65-year-old female presented with a substernal exophytic mass displacing the trachea to the right after a left thyroid lobectomy 4 years ago. Cytology revealed a retained substernal thyroid. She is scheduled for a substernal thyroidectomy through a median sternotomy. Discussion In all partial or complete thyroidectomy cases, care should be taken to palpate or to use intraoperative ultrasound (IOUS) for any extra thyroid mass. An intuitive surgical approach is needed to evaluate for possible embryologic anomalies of the thyroid. There are two thyroid anlagen that can explain ectopic aberrant anomalies: the median anlage-thyroid rest and the lateral anlage from the ultimobranchial body of the fourth pharyngeal pouch. Surgeons should keep in mind that multiple ectopic thyroid glands could be present in any thyroidectomy procedure.

“…In a minority of subjects, as is the case in our Patient 3, dual thyroid ectopy is diagnosed [23,24], and such patients constitute only about 5% of cases of thyroid ectopy [16]. One patient with triple ectopia was also reported [25]. Rarely, ectopic thyroid may be accompanied by other thyroid developmental anomalies, i.e.…”

Despite the fact that TSH screening in newborns is currently conducted in most developed countries, patients with thyroid ectopy born before the procedure was introduced or those in whom the screening failed to establish diagnosis, might still appear. In this paper we revise the current state of knowledge regarding the clinical presentation, diagnosis, and treatment of patients with thyroid ectopy. As an example, we report diagnostic and therapeutic difficulties in our three patients with thyroid ectopy remaining undiagnosed and untreated during early childhood. Introduction of neonatal screening for congenital hypothyroidism does not guarantee that all patients with thyroid ectopy will be correctly diagnosed and properly treated, due to the possibility of falsely negative results of TSH screening or lack of compliance from parents. Visualisation of an ectopic thyroid on ultrasound examination may be challenging for unexperienced sonographers; muscles in the thyroid bed may be misdiagnosed as heterogeneous and hypoechogenic thyroid gland with features suggesting autoimmune thyroid disease. Thyroid scintiscan is crucial for confirmation of the diagnosis of thyroid ectopy.In conclusion, hypothyroidism due to thyroid developmental anomaly should be taken into consideration in cases of hypothyroidism and normal thyroid autoantibodies in a patient at any age.
