Cavernous Hemangiomas of the Lung With Secondary Polycythemia

A recent review of the literature on hemangioma of the lung has impressed me sufficiently to indicate that the report of such an observed case complicated by secondary polycythemia is warranted; more so because a record of such a complication as hemangioma of the lung in any type of polycythemia could not be found. Several reports, however, of malignant types of hemangiomas of the lung and pleura were found, as well as those of both benign and malignant lesions of other viscera. De Lange and de Vries Robles¹and Bowers²reported cases of the benign type in the lungs of infants. To further the interest, Hirsch³recently published an article on pulmonary changes in polycythaemia vera. Roentgenograms taken in the case here reported showed shadows similar to those demonstrated in Hirsch's cases. He consented to compare the roentgenograms taken in this case with those taken in his
