Clinicopathologic study of mucoepidermoid carcinoma of the lung.

Abstract

These results suggest that mucoepidermoid carcinoma of the lung should not be viewed uniformly as a low grade malignant tumor, but that this tumor can sometimes be highly malignant with a poor prognosis. Since this tumor is often difficult to distinguish from adenosquamous carcinoma, and because accurate distinction between these two types of tumor seems to be essential for establishing a prognosis, there is an urgent need for a valid pathological method for differential diagnosis of mucoepidermoid carcinoma.
