Overview of Diagnostic Terminology and Reporting



Lung cancer is the leading cause of cancer death in the United States. A number of new treatment options have impacted the need for accurate diagnosis and classification of primary pulmonary carcinomas. Not only must carcinomas be separated into small cell and non-small cell types, but adenocarcinoma must be separated from squamous cell carcinoma. Cytologic material obtained from pulmonary lesions displays a range of abnormalities varying from the clearly benign to the clearly malignant. The-six category system proposed by the Papanicolaou Society of Cytopathology categorizes the cytomorphologic features into clinically useful groups with estimated risks of malignancy.
