A 3D Digital Model for the Diagnosis and Treatment of Pulmonary Nodules

Multiple chronic benign pulmonary nodules
Abstract:
Four cases are discussed in which were found unusual multiple chronic pulmonary nodules: leiomyomatous hamartomas, rheumatoid nodules, multiple histoplasmomas, and possible multiple plasma cell granulomas (hyalinizing pulmonary nodules). In each case the initial impression of metastic malignancy was countered by more than 2 years' observation, during which time the lesions appeared to be benign. Histologic examination is necessary to exclude malignancy, although a definitive diagnosis may be difficult to establish.
