“…Clinical reports of extra-lingual ectopic thyroid tissue are rare. We found a few studies of ectopic thyroid in adrenal gland (4,5), gallbladder (6), jejunum (7) and mesentery (8) but not pure ectopic thyroid in the breast. The etiology of this abnormality is not fully understood.…”

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.

“…Guerra et al [4] reported that adrenal gland thyroid is very rare and is di cult to understand based on thyroid embryology. However, on the basis of the reported cases [5][6][7][8][9][10][11][12][13][14], the adrenal gland is not an uncommon site of abdominal ET. The cause of adrenal gland ET remains unknown.…”

Background : Although ectopic thyroid can be found in thoracic locations, the discovery of abdominal ectopic thyroid is often an accidental event. Moreover, abdominal ectopic thyroid is easily misdiagnosed due to the rarity of these cases and the difficulties in the preoperative diagnosis process. Thus, we aimed to assess the prevalence and features of abdominal ectopic thyroid and to highlight the current knowledge about the clinical characteristics and management of this condition by analyzing a case report of abdominal ectopic thyroid and reviewing the literature. Case presentation : A 70-year-old woman with a 3-year history of gradually increasing abdominal distension in the right lower quadrant of the abdomen was admitted to the hospital. Contrast-enhanced computed tomography (CT) of the abdomen revealed a retroperitoneal mass. The patient underwent Da Vinci robotic surgery, and the retroperitoneal mass was completely resected. Subsequently, the pathologic diagnosis of the mass was ET. The patient had no discomfort or symptoms when she was discharged from the hospital and at the postoperative 1, 3, 6, 9 and 12 month follow-up. The summary of literature review suggested that abdominal ectopic thyroid is still rare although there are some reports. Nonetheless, the cause of abdominal ectopic thyroid is unclear, and abdominal ectopic thyroid has the following characteristics: more common in women than in men, asymptomatic in the majority of the cases, difficult to diagnose, and found by excluding metastasis. Most ectopic thyroid is treated with surgery, and minimally invasive techniques have been increasingly performed. Conclusion : This is the first report on Da Vinci robotic resection for large rare retroperitoneal ET, and this case highlights that ET should be considered when patients present with similar imaging findings in the abdomen.

“…Localizaciones mas distantes del trayecto normal de migración han sido reportados, como el esófago, ovario, corazón. Estas localizaciones son menos frecuentes [6][7][8][9] . Se ha reportado un solo caso de localización axilar.…”

“…En nuestro caso, se trataba de un nódulo bien delimitado, sin atipias celulares correspondiente a una lesión benigna. Una metástasis, un cancer tiroideo 9 o una transformación maligna del tejido tiroideo ectópico, raramente descrito como carcinoma papilar y folicular [11][12][13] , fueron excluidos.…”

Palabras claves : nódulo subcutáneo, axila, tejido tiroideo ectópico SUMMARY A 83 year-old woman presented with a ectopic thyroid nodule in the axilla. Ectopic thyroid tissue is a rare condition defined as thyroid tissue beyond its normal pretracheal localization. Abnormal embryonic development and/or migration of the thyroid gland or heterotopic differentiation of endodermal cells are at the origin of ectopic thyroid tissue. Sublingual ectopic thyroid tissue accounts for 90% of the cases. In most patients are completely asymptomatic. Therapeutic decisions depend on clinical presentations and symptoms. Histologic and immunohistochemestry analysis are the only definitive method of diagnosis.
