Carotid Body Tumor Diagnosed by On-Site FNA: a Case Report.

Carotid body tumors (CBTs) are paragangliomas which arise from the chief cells of the carotid body, usually located at the bifurcation of the common carotid artery. A 45-year-old male presented with swelling over the right cervical region for 1 year. Based on location, FNA and radiologic investigations, the diagnosis of CBT was made; later, confirmed on histopathology. Although FNA is seldom suggested due to its location and possibility of severe bleeding complications for the diagnosis of CBT, it can however be detected incidentally. Our case, the diagnosis was incidental cytological diagnosis on rapid onsite staining.
