Introduction: Carotid Body Tumors (CBT) are rare benign neoplasms of neural crest origin located at the carotid bifurcation. They are more common at high altitudes. On the other hand, the incidence of Papillary Thyroid Cancer (PTC) is steadily rising in the whole world. We report a small series of patients who presented a CBT associated with PTC simultaneously or at different times. Materials and methods: Among 255 clinically diagnosed CBT, 230, arising in 217 patients (13 bilateral), were operated in Quito, Ecuador. In 13 (6%) cases, a malignancy at other localization was found. A PTC was treated surgically in 8 of them, 3 previously, and 3 after the CBT surgery and 2 simultaneously. Results: There were no postoperative complications. Median follow up was of 66 months after CBT surgery and 66 months for thyroid cancer surgery. One patient died for malignant local recurrence and pulmonary metastasis of a CBT. No recurrence of PTC occurred in any patient. Conclusion: Association of CBT and PTC is very uncommon but it could be expected to occur less rarely in regions where both lesions have a higher incidence. If they are present simultaneously an adequate and complete surgical procedure for both lesions can be performed without morbidity.
