[Electron-radioautographic study of parasympathetic paragangliomas (chemodectomas) of the neck].
Chemodectomas, after the surgery, were studied in 7 patients. Morphologically their malignancy is proven on the basis of pronounced cell polymorphism, atypia, invasion of tumour cells through the vessel wall into their lumen. Besides rare mitoses, proliferative (DNA synthesis) and protein synthetic (RNA synthesis) activity in clear and dark cells was not observed in the presence of intensive biosynthetic processes in the stroma cells.
