Papillary Carcinoma Within Thyroglossal Duct Cyst: A Rare Midline Coexistence

Thyroglossal duct cysts (TDCs) develop papillary carcinomas in very rare cases. Mostly, in such cases, the diagnosis is established after the excision of a clinically benign TDC. An anterior neck mass was found in a 43-year-old man with papillary carcinoma arising in a TDC. Clinical, radiological, and analytical controls are necessary for the management of papillary carcinoma in the TDC. There is no need for thyroidectomy unless there are palpable abnormalities in the gland or significant changes on an ultrasound. The outcome of the papillary carcinoma does not seem to be significantly impacted by routinely performed thyroidectomy.
