A Rare Cause of Recurrent Dyspnea in Emergency Service: Carotid Body Tumor.

Carotid Body Tumors (CBT) are rare neoplasms that are represent 0.5% of neoplasms of the head and neck. In the current report, we present the case of a patient with syncope and recurrent dyspnea attack who, after other causes had been ruled out, was found to have a left-sided CBT as the cause of her problems. She was monitored in the emergency department for 24 hours. Lastly, she was discharged by arranging symptomatic therapy because she refused the surgical intervention due to fear of death. Despite the development of therapy techniques, CBT continue to have high incidence of complications like in our case.
