Clinical Information

Adenocarcinoma of Lung - A carcinoma originating in the lung and the most common lung cancer type in never-smokers. Malignant cells exhibit distinct features such as glandular epithelial, or tubular morphology. Mutations in KRAS, EGFR, BRAF, and ERBB2 genes are associated with this cancer.

Pulmonary Blastoma - A malignant neoplasm of the lung composed chiefly or entirely of immature undifferentiated cells (i.e., blast forms) with little or virtually no stroma. (From Stedman, 25th ed)
