Papillary Adenoma of the Lung with Pulmonary Sequestration: A Case Report / 대한흉부외과학회지

ABSTRACT

Papillary adenoma of the lung is a very rare tumor in humans. Papillary adenoma is benign, and morphologically distinctive neoplasm.Since Fanton et al. firstly described a bronchial tumor showing Clara cell features,only a few cases having features of both Clara cells and type II pneumocytes have been reported.The immunohistochemical and ultrastructural findings hint at an origin from type II pneumocytes or Clara cells.Noguchi et al. demonstrated the presence of surfactant apoprotein in cytoplasm of tumor cells in a case of papillary adenoma indicating type II pneumocyte-like differenciation of the tumor cells. The tumor was encounted in a asymptomatic patient in a mass-survey chest X-ray examination. The chest X-ray films showed the tumor as well dermacated small lesion. We reports a case of papillary adenoma of the lung with pulmomary sequestration with review of articles.
