Carcinomatous abscess of the lung.

or tuberculous cavities has prompted us to review all the cases of neoplastic abscess seen in the Newcastle-upon-Tyne Regional Thoracic Surgery Centre over the last 12 years. From 1940 to 1951 70 cases of neoplastic abscess were admitted to the clinic, and this paper reports the results of our study of these cases and discusses the main problems encountered in diagnosis. Our criterion in selection was a radiological one, and only those cases of bronchial carcinoma presenting clear evidence of cavitation or abscess formation on a chest radiograph were included in the series.
