Pathological and radiological correlation of endobronchial neoplasms: Part I, Benign tumors

Abstract

Benign endobronchial lung neoplasms are extremely rare. Most such neoplasms are of mesenchymal origin; however, neoplasms of submucosal gland origin and surface epithelial origin also occur. The symptomatology and radiographic features of these tumors are often indistinguishable from those of malignant lung tumors. However, recognition and early diagnosis of these lesions may allow for conservative treatment and excellent patient outcome. The clinicopathologic and radiological features of these pulmonary neoplasms are discussed.
