Surgical implications of solitary tumors of the lung

1. 1. Two large groups of patients, all of whom presented the radiographic picture of a solitary intrapulmonary tumor, have been analyzed and compared. 2. 2. The incidence of malignancy, as we have previously emphasized, is extreme, being over 50 per cent in each group. 3. 3. The more common lesions entering into the differential diagnosis have been briefly discussed. Particular attention has been paid to the frequency with which histoplasmosis accounts for the so-called “tuberculoma.” 4. 4. Because the correlation between clinical impression and the histology of any particular lesion is extremely tenuous, and since the various diagnostic tests are rarely helpful, prompt surgical excision would seem to constitute the only logical approach to the problem of the solitary tumor of the lung.
