Clara cell adenocarcinoma. Light and electron microscope studies.
A 52-year-old black man was found to have a round density in the right lower lung field. An exploratory thoracotomy disclosed a tumor in the right middle lobe, which by light microscopy was composed of malignant Clara cells. The electron microscopic studies confirmed the Clara cell nature of this neoplasm.
