ABSTRACT
Paragangliomas are rare lesions of the endocrine system that can be treated either by embolization preoperatively followed by surgical excision or by surgical excision or radiotherapy. In this report, we present an extremely rare location of a nonfunctional paraganglioma in the head and neck region, located in the right supraclavicular fossa, which was misdiagnosed as a thyroid tumor, in a 72-year-old female patient. Imaging revealed a 2.5 × 4.5 × 2 cm well-defined vascularized mass. Fine-needle aspiration (FNA) on the tumor was not diagnostic initially; however, a third attempt revealed thyroid cells suggesting the existence of an ectopic thyroid tumor. FNA was additionally performed on the right thyroid lobe, revealing atypical follicular colloid cells of the Bethesda 3 category. Therefore, the excision of the ectopic thyroid tumor along with right lobectomy was planned. No embolization was initiated preoperatively in this case. Histopathology revealed that the supraclavicular mass was a paraganglioma. Paragangliomas supplied by the subclavian, innominate, and common carotid artery are rarely reported, and to our knowledge, this is the third case to be reported worldwide.
