Abstract
An 11-month-old female Saanen goat, weighing 12.7 kg, was taken to the Veterinary Hospital of the Federal University of Minas Gerais because of sternal recumbency. On clinical examination, the animal was much smaller than expected and had hair similar to that of puppies and areas of hyperpigmentation on the head and dorsocervical and dorsothoracic cranial regions. Radiographic examination revealed fractures in both femurs and severe generalized osteoporosis. Given the unfavourable prognosis, the animal was euthanized. Necropsy revealed generalized pallor, muscular atrophy of the pelvic limbs and little reserve of subcutaneous adipose tissue. Both femurs had complete and closed diaphyseal fractures. The second lumbar vertebra was severely reduced in length as a result of a fracture, with dorsal displacement of the vertebral body towards the vertebral canal and compression of the spinal cord. Long bones and vertebrae had severe cortical thinning, enlargement of the medullary canal and reduced resistance. The thyroid gland was not in its normal anatomical location. A pale red nodule (1.0 × 0.4 cm) in the serosa of the middle third of the trachea, close to the thoracic entrance, was confirmed as ectopic thyroid tissue. Microscopically, the bones had evidence of growth arrest and severe osteoporosis. The ectopic thyroid nodule was hyperplastic with severe hypertrophy of follicular cells. The spinal cord was compressed by vertebral fractures and had focally extensive and severe myelomalacia. Based on the pathological features, the case was diagnosed as thyroid dysgenesis characterized by eutopic thyroid agenesis and ectopic thyroid tissue, associated with interruption of bone growth with dwarfism, osteoporosis and spontaneous secondary fractures with compression of the lumbar spinal cord.

Abstract
Ectopic thyroid tissue is very rare, but the coexistence of ectopic and eutopic thyroid glands is even more rare. The recognition of this diagnosis is important in patients who are being treated for thyrotoxicosis, but it is also crucial to exclude other associated serious disease conditions. In this article, we report three different cases that showed ectopic thyroid tissue with the coexisting presence of an eutopic thyroid gland. All three cases showed different outcomes. The recognition of this condition is of great importance because it alerts the referring physicians to this rare, yet possible occurrence and the potential pathological conditions associated with it. The first case showed how imaging could help outline even small ectopic thyroid tissue outside of the neck region even in cases where histopathological confirmation is difficult. The second case was very rare as thyroid carcinoma originated in ectopic thyroid tissue. In the last case, the initial imaging was misleading as it mimicked greatly ectopic thyroid tissue, and only detailed history and careful inspection of the images could lead to the correct interpretation of the findings.

Diagnosis and treatment of mediastinal ectopic thyroid tissue with normally located thyroid gland and primary hyperparathyroidism: a case report. Gland Surg 2021; 10:1532-1541.

Abstract
Mediastinal ectopic thyroid tissue (ETT) is rare entity, accounting for 1% of all mediastinal tumours. A 53-year-old lady, presented with cough and atypical chest pain. A computed tomography (CT) scan of chest showed a 95 mm × 75 mm × 115 mm tumour mass; CT guided biopsy of mediastinal mass showed ETT. Thyroid scintigraphy with Technetium-99m (99mTc) pertechnetate showed homogenous and intense uptake in the thyroid gland (TG) lodge and in the mediastinum. Primary hyperparathyroidism (PHPT) was diagnosed during laboratory evaluation. Technetium-99m sestamibi (99mTc-MIBI) parathyroid scintigraphy with single photon emission CT (SPECT)/CT showed uptake of radionuclide in two locations, one in the eutopic position [right inferior parathyroid gland (PTG)] and second ectopic (mediastinal). After surgery, histopathological examination confirmed mediastinal ETT and two PTG adenomas. During follow-up, laboratory analyzes were maintained within the reference range and the patient remained stable and free of symptoms and clinical signs, which supports a good prognosis. The existence of an ectopic mediastinal thyroid and an ectopic parathyroid tissue may be partly explained by a similar embryological origin. Diagnosis of ectopic thyroid and parathyroid tissues is demanding; requires a multidisciplinary team and approach using highly accurate radiological and nuclear imaging. The simultaneous existence of mediastinal ETT, nodular eutopic TG and PHPT for which two adenomas are responsible (cervical eutopic and mediastinal ectopic) is a complex diagnostic and therapeutic challenge, which we have described so far as unique. Comprehensive and multidisciplinary surgery planning is a cornerstone of treatment, when recommendations in guidelines are lacking.

Abstract
The current study reports the case of multifocal ectopic thyroid tissues in the breast. Ectopic thyroid tissue is an uncommon entity found not only in the cysts of thyroglossal ducts, but also along the thyroglossal duct. The most frequent location of this tissue is the base of the tongue, but they can also occur in the anterior tongue, submandibular or sublingual region, larynx, trachea, mediastinum and heart. Only a single case of ectopic thyroid tissue in breast has been previously reported in English literature. However, the current case was associated with abnormal embryological development compared with previous reports, which are attributed to abnormal implantation.

A unique presentation of ectopic thyroid, a case report. Int J Surg Case Rep 2016; 29:185-188.

Abstract
Previous description of ectopic thyroid tissue has not included point tenderness as a presenting symptom. Ectopic Thyroid shoudl be included in teh differential diagnosis of point tenderness with an associated mass or lesion on imaging. Management of both symptomatic ectopic thyroid and esophageal perforation with periesophageal abscess is surgical intervention. It is important to perform due diligence in the work up of a patient without compromising the patient’s safety to do so.
Introduction This case presents a painful ectopic thyroid, an unusual presentation, in an atypical location. The patient’s history of an ingested fish bone, her acute presentation, and inconclusive imaging, made this case a diagnostic dilemma. Presentation of case 61-year-old female presented with acutely worsening history of left throat pain and dysphagia after swallowing a fish bone. CT scan showed a foreign body in the anterior wall of the cervical esophagus. EGD studies were inconclusive. Surgical exploration identified and excised a multinodular cystic lesion without connection to esophageal lumen. Pathology described multinodular thyroid parenchyma with chronic inflammation and no evidence of malignancy. No foreign body was located. Discussion Based on the patient’s history, imaging, and acute presentation, an esophageal perforation with abscess formation was the most likely diagnosis. Surgical exploration was the necessary intervention for this patient’s acute symptoms as both a diagnostic and therapeutic tool. The diagnosis of ectopic thyroid tissue from pathology of the excised cystic lesion was unexpected, as the location of tissue and the painful presentation are not typical characteristics of ectopic thyroid tissue. Management of the this case illustrates the dilemma faced in determining the appropriate work up for a patient, without compromising the patient’s safety. Conclusion Though painful presentation and this case’s location are rare, ectopic thyroid tissue should be included in the differential diagnosis of point tenderness with an associated lesion on imaging.

Abstract
Ectopic thyroid tissue (ETT) is an uncommon entity that may be found anywhere along the line of the obliterated thyroglossal duct, usually from the tongue to the diaphragm. We performed a retrospective analysis of patients undergoing surgical treatment for thyroid disease between January 2000 and December 2013, seeking for ETT All patients with prior neck surgery or trauma were excluded. The clinic-pathologic features, prevalence and diagnosis of the lesions were collected and analyzed. Out of 3092 included patients, 28 ETT were identified (0.9%). The anatomical site of ETT was as follows: lateral cervical in 6 (21.4%), along the thyroglossal duct in 6 (21.4%), mediastinal in 5 (17.9%), lingual in 5 (17.9%), sublingual in 3 (10.7%), and submandibular in 3 (10.7%). Histopathology revealed 27 benign lesions and 1 (3.6%) papillary carcinoma. ETT is found in less than 1% of patients receiving thyroid surgery. Diagnosis of ETT requires clinical imaging. Surgery is a prudent choice due to the potential of malignant evolution of ETT.
