Introduction: Triple ectopic thyroid is a rarely described entity with only eight previous cases reported in the literature. This case is the first-described discovery of triple ectopic thyroid in a middle-aged male.
Case Report: A 46-year-old male with a past medical history of hypothyroidism and cannabis use disorder presented to his primary care physician with a globus sensation and left cervical lymphadenopathy for two weeks. A computed tomography (CT) scan of the neck with contrast identified three high attenuation areas: the first in the midline floor of the mouth extending posteriorly to the base of the tongue, the second at the base of the tongue, and the third in the midline of the neck just beneath the hyoid bone. Thyroid tissue was not identified in the orthotopic location. A follow-up thyroid uptake and scan confirmed that each of these high attenuation areas was also iodine avid, consistent with thyroid tissue.
Conclusion: The few cases of triple ectopic thyroid have mainly been discovered in female children with the most commonly described locations being the lingual (88%) and suprahyoid (88%) regions. Most patients were symptomatic with midline neck swelling. Overall, we describe the first case of triple ectopic thyroid in a middle-aged male and the first patient with ectopic thyroid located in the midline mouth.
