- Thyroglossal duct remnants are commonly seen:
- Comprising more than:
- 75% of midline neck tumors in children
- 7% in adults
- Comprising more than:
- Finding a cancer within one of these cysts is rare:
- One large study reported a prevalence of cancer:
- In 1.3% of remnants
- PTC is the most common tumor (90%):
- Most are less than 1 cm
- They are typically confined to the cyst
- One large study reported a prevalence of cancer:
- Because so few cases have been reported,:
- No consensus exists about the optimal management
- Most agree that a Sistrunk procedure is the best way to excise a thyroglossal duct cancer:
- The necessity for total thyroidectomy is controversial:
- As only 25% to 56% of patients have concomitant malignancy in the thyroid
- A retrospective analysis of 18 patients treated at one institution found that:
- 75% had lateral with or without central lymph node metastases
- 56% were found to have tumor foci in the thyroid
- Twelve patients were given radioiodine
- With a median follow-up of 12 years (range 1 to 22 years), 11 patients had stimulated thyroglobulin levels available; 10 were undetectable, the other was 2 ng/mL, and all had a negative neck ultrasound
- Other studies have reported similarly encouraging results with follow-up, regardless of the treatment
- The necessity for total thyroidectomy is controversial:
