Stable Bronchogenic Carcinoma

Abstract

Five cases are presented in which repeated roentgenographs examinations were made of intrapulmonary noncalcified opacities which remained stable in size for an average of three and a half years.

In each case, following a prolonged observation period, the lesion was found to be a primary malignant tumor of the lung. A plea is made for histologic diagnosis of all persistent, apparently static, noncalcified intrapulmonary opacities.
