[Bronchial cancer of several histological components: an additional argument for operating on small-cell cancers].

: Analysis of the histological data of the primary lung cancer can now be refined by means of electron microscopy. A particular sub-group has been isolated in this way: composite cell anaplastic cancer. The authors report a case of this type of cancer and present the various histological hypotheses proposed to explain this composite nature; they define the current therapeutic approach based on these data.
