Carotid body tumors (paragangliomas) are very rare, highly vascularized and usually benign tumors, originated in the carotid body chemoreceptors. We present the cases of two asymptomatic patients referred for left cervical mass; preoperative study was CT and CT angiography, respectively, which are consistent with carotid body tumors. The tumors were completely removed by subadventitial disection without complications; the biopsy was compatible with paraganglioma. No evidence of recurrence could be found.
