title: Papillary carcinoma of hyoid.
abstract: BACKGROUND
  Thyroglosal duct cyst is a common anomaly with an incidence of 7% in adults, the rate of carcinoma in TGDC is 0.7-1.6%, and are extremely rare those originated in the hyoid bone.
  
  
  METHODS
  A 60 years old male patient, had a hard mass in the anterior neck. CT revealed a hyoid tumor. Hyoid bone resection was performed, the pathological report show a conventional papillary carcinoma in bone tissue. We rule out primary tumor in thyroid gland. Five years later, he developed a neck node recurrence. Total thyroidectomy and a selective left neck dissection (II-IV levels) was performed. He received radioiodine adjuvant treatment.
  
  
  CONCLUSIONS
  Hyoid cancer originates of a persistent thyroglosal duct remnants inside hyoid bone.
  
  
  CONCLUSIONS
  We propose to add a new subdivision to pathology derived from thyroglosal duct remnants). The diagnostic approach with ultrasound and CT are necessary. A primary in te hyoid gland mustang be discorded, and then the entire hyoid bone must be removed. Treatment of the thyroid gland and neck should be considered when there are significant risk factors of recurrence, similarly to thyroid cancer based on the risk assessment.
