“…Ectopic thyroid tissue is mainly found as inclusions within cervical lymph nodes, as a sequestered nodule/parasitic nodule, or in soft tissue in the midline, anywhere along its migration path from the primitive foregut to its eventual position in the neck [8,9]. Very rarely, ectopic thyroid tissue can also be found in other locations, including but not limited to the thorax and abdomen [10]. The mechanisms for formation of ectopic thyroid tissue is believed to be related to misplacement during embryonal migration, or heterotopic differentiation in aberrant endodermal tissue [10].…”

We describe a case of ectopic cervical thyroid tissue which was involved by fibrosing Hashimoto's thyroiditis and which mimicked metastatic papillary thyroid carcinoma both on fine needle aspiration cytology and biopsy. The patient underwent total thyroidectomy which revealed fibrosing Hashimoto's thyroiditis, but no carcinoma. The entire thyroidectomy specimen was submitted for histopathological assessment. Even in the resected thyroidectomy specimen, there were cytological changes that were strongly reminiscent of papillary thyroid carcinoma. However, interpreted in the correct clinico-pathological context, these cytological alterations were deemed to be reactive secondary to the fibro-inflammatory process.

“…The other sites of abdominal ET included the duodenum [29], mesentery [30], appendix [31], gynecological organs (ovary, uterus and fallopian tube) [32][33][34] and others. Although few cases of other sites of abdominal ET have been reported, struma ovarii is a noteworthy disease because this condition may be easily misdiagnosed, and determining benign disease from malignant disease is di cult.…”

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.
