Abstract
Thyroglossal duct carcinoma (TGDC) is a rare disease with many reported cases. The recurrence in such cases after surgical removal may be seen after cyst excision. Sistrunks operation is recommended, as it has a very low recurrence rate. The case which present as recurrence demonstrate histological pattern similar to a thyroglossal duct cyst. We present a case of recurrence of thyroglossal cyst, with a solid internal component on ultrasonography (USG). On histopathology the solid internal component proved to be papillary carcinoma. To our knowledge, our paper is the first case of recurrent thyroglossal cyst with a papillary carcinoma preoperatively suspected on USGBangladesh Journal of Medical Science Vol.16(1) 2017 p.166-169
Highlights
The thyroid gland descends from the foramen cecum to its location at the point below the thyroid cartilage
The incidence of carcinoma in thyroglossal duct cysts is less than 1%. (5,6)
Based on these findings we reported the USG as recurrent thyroglossal cyst with possible PTC
Summary
The thyroid gland descends from the foramen cecum to its location at the point below the thyroid cartilage. Thyroglossal duct cyst accounts for 70% of congenital neck masses(2) and usually manifests as an enlarging painless neck mass in children or young adults If infected it may present as a red warm painful lump. CASE REPORT A 36 years old lady presented in the out patient department for USG neck. She had undergone a thyroglossal duct cyst excision 12 years back. Lateral cervical lymphadenopathy was seen with right level I node Based on these findings we reported the USG as recurrent thyroglossal cyst with possible PTC. We requested for revision of the diagnosis, and the reviewing pathologist reported the case as PTC in a thyroglossal cyst!
