Thyroglossal duct cyst in the suprasternal region in an adolescent.

Abstract

Thyroglossal duct cysts are the most common midline neck swelling in childhood, occurring in the line of descent of the thyroid, anywhere between the foramen caecum and the isthmus of the thyroid. However, the most common location is the thyrohyoid. We present a case of an adolescent male who presented with a suprasternal mass, which was clinically diagnosed as a branchial cyst. However, on histopathology, it was diagnosed to be a suprasternal thyroglossal cyst. With this article, we aim to highlight the importance of keeping thyroglossal cyst as a differential diagnosis for midline neck swelling, even below the location of the thyroid gland, so that proper excision of the tract can be planned and review the literature on suprasternal thyroglossal cyst.
