Overview

Carotid body tumor must be differentiated from other diseases that cause neck mass including schwannomas and lymphadenopathy.

Differentiating Carotid Body Tumor from Other Diseases

Differentiating carotid body tumor from other diseases causing neck mass

Neck masses may be classified into subgroups including congenital abnormalities, inflammatory, and malignant lesions.
