title: [Intrapulmonary chemodectoma. A new case with ultrastructural study].
abstract: The authors report the case of a 40-year old woman who presented with a round tumour in the middle lobe of the right lung. Once removed, the tumour proved to be an intrapulmonary chemodectoma. Chemodectomas are tumours that are rarely present in the lung. Their pathogenesis is open to discussion. Their study by electron microscopy is interesting, as it shows grains of neurosecretion and provides additional information on the morphology of chemoreceptors.
