Carotid body tumors (CBTs) or chemodectomas are non-chromaffin paragangliomas. Carotid body tumors appear as painless, slowly expanding masses located in the upper part of the neck under the chin. On physical examination, it presents as a soft, non-tender mass in the lateral aspect of the neck that can move more freely in a horizontal plane than vertically, referred to as a positive Fontaine sign. The differential diagnosis of a lateral neck mass, rarely seen in adults, includes lymphadenopathy, branchial cleft cysts, salivary gland tumors, neurogenic tumors, and carotid artery aneurysms. A 62-year-old female patient presented with only neck swelling. CBTs are rarely detected in the etiology in cases of lymphadenomegaly. We wanted to present the case to the literature.
