Cáncer papilar en quiste del conducto tirogloso: serie de casos

Introduction: Thyroglossal duct cysts (TGDC) are unusual remnants of the thyroid gland. Papillary carcinoma of the thyroglossal duct is extremely rare in clinical prac­tice. Case series: Four cases of patients with papillary carcinoma of the thyroglossal duct cyst are presented. Discussion: Papillary carcinoma of the thyroglossal duct cyst is considered a rare finding, occurring in approximately 1% of thyroglossal duct cyst cases. Total, thyroidectomy is recommended for cases with malignant trans­formation, especially if there is evidence of invasion or when the tumor exceeds 1 centimeter in size. Conclusion: Carcinomas arising from thyroglossal duct cyst remnants are rare and may present only as swelling of the anterior neck. The need for thyroidectomy due to thyroid disease, whether malignant or benign, is not un­common in patients with thyroglossal duct cyst.
