Primary papillary carcinoma in thyroglossal cysts. Case reports and literature review

The thyroglossal cyst can exceptionally appear as a primary cyst carcinoma. We discuss a series of 6 adult patients, assessed for long-lasting asymptomatic suprahyoid or lateralto-larynx mass. The images showed a heterogeneous mass invading adjacent soft tissues. Fine needle aspiration biopsy did not contribute to diagnosis. We performed a Sistrunk procedure in all cases, 3 combined with total thyroidectomy and 1 with neck dissection. The postoperative course was favourable. No additional treatment was required, without evidence of recurrence in classifications based on size and extent have been proposed to define the surgical treatment of such cysts.
