Presentation Date: March 24, 2015; Expires: March 24, 2018
Major diagnostic difficulties in pulmonary cytology include the differential diagnosis of benign/reactive conditions versus carcinoma and classification of neoplasms. The new targeted therapies require accurate classification of lung tumors. Improved survival in cancer patients has led to the increased occurrence of second and third primaries, necessitating the use of immunocytochemical stains to determine the primary source. Furthermore, the increasing need for molecular studies mandates prudent use of immunostains in order to conserve tissue. In this webinar the morphologic criteria to distinguish benign from malignant lesions and appropriate use of immunostains in the differential diagnosis of lung tumors will be discussed.
