Abstract
Ectopic thyroid is thyroidal tissue located far from its anatomic place.
A patient under our observation displayed left submandibular swelling.
The FNAC test report described a follicular adenoma.
Based on the FNAC diagnosis, we surgically removed the mass.
The post-operative follow-up was uneventful.
Introduction
The term ectopic thyroid refers to the presence of thyroid tissue located far from its usual anatomic placement and with no vascular connection to the main gland. The presence of swelling in atypical locations is diagnostically differentiated from other pathologies like pleomorphic adenoma or carcinoma, inflammatory lesions like sialadenitis, neurogenic tumors, paraganglioma, fibrolipoma and lymphadenopaties of diverse etiologies.
Presentation of case
Here we present the case of a submandibular ectopic thyroid in a 67 year old woman. She came to our attention for a left submandibular swelling. The anamnesis did not show related pathologies, as well as blood tests. Diagnostic image studies and a FNAC were performed. The mass was surgically removed and histopatology showed a follicular adenoma in the contest of the capsulated lesion.
Discussion
It is important to not underestimate these types of lesions and procede with hematochemical, instrumental tests and above all surgery that can eliminate any diagnostic uncertainty and on the whole be therapeutic.
Conclusion
It should not be forgotten that ectopic thyroid tissue can be a site for adenoma or papillary carcinoma and thus any watch and wait strategy should be avoided.
