Since lung cancers are common, most practicing physicians are experienced with
routine primary lung cancers and have no problems recognizing them. However, there are many histologic variations of the common cancers as well as unusual cancers that occur in the lung. While many of these less common cancers are recognized and classified on routine histologic sections, in others the diagnosis, classification, and prognosis are aided by recently developed immunohistochemical and molecular techniques. Therefore, the purpose of this article is to: (1) describe and illustrate common lung cancers with emphasis on less common histologic variations, especially of actual or potential clinical importance; (2) describe and illustrate the many uncommon cancers with distinct clinical behavior; (3) outline and describe newer diagnostic techniques and emerging concepts, such as molecular pathology, which may be of prognostic significance in the study of the lung cancers. |
