Thyroglossal Duct Cyst- A Rare Site Presentation Diagnosed On Fnac

Midline neck developmental anomalies are due to persistence and cystic dilation of thyroglossal duct. Thyroglossal duct (TGD) is the embryonic tract characterized by the presence of epithelial lined remnants and heterotopic thyroid tissue. Though it is more frequently encountered in children, prevalence in adult population is 7%. It manifests as anterior midline neck mass between hyoid bone and mandible. Reported incidence of malignancy in TDC is less than 1%1 . Appears in midline neck anywhere along path of TGD, from foramen cecum in tongue base to suprasternal region. However, suprasternal region is rare site. We are presenting this case for its rare location.
