Autoradiographic study of parasympathetic paragangliomas (chemodectomas) of the neck.

ABSTRACT

Study of the morphofunctional characteristics of chemodectomas of the neck by photoautoradiography (semithin sections) showed the absence of protein-producing and proliferative activity in light and dark tumor cells against the background of strained biosynthetic processes in stromal cells. Invasion of capillary walls by tumor cells with their release into the capillary lumen is a prerequisite for metastases of these tumors.
