Papillary adenocarcinoma of the lung: radiologic and pathologic findings.

摘要

We describe the radiologic and pathologic findings of papillary adenocarcinoma of the lung in three patients. The tumor appeared as a peripheral lung nodule (n = 1) or a mass (n = 2) on chest radiographs. On CT, the tumor appeared as a solitary pulmonary nodule, as a mass containing internal bubble lucencies with surrounding ground-glass opacity and satellite micronodules, and as a triangular mass with satellite micronodules. On pathology, all tumors showed distinct histologic features with papillary architecture, distortion and/or destruction of normal pulmonary architecture, and nuclear atypism.
