abstract: Twenty-nine cases of lung cancer occurring in men aged 40 or less were examined at autopsy. Histologic types of cancer and metastatic patterns in this group of patients were similar to those seen in middle-aged or elderly patients except for a lower occurrence of lymphatic spread in the younger group.
