[Clinico-morphologic and electron microscopic characteristics of chemodectoma of the neck]

Chemodectoma of the neck is one of the rare tumors occurring in man. The paper presents an observation of cervical chemodectoma found in a patient aged 31 years. For preoperative differential diagnosis, carotid angiography, ultrasound and radioisotopic examinations were used, which allowed the tumor located at the bifurcation of the left carotid artery to be diagnosed. The material taken during the surgery was histologically and electron microscopically examined to verify benign chemodectoma (an alveolar variant).
