Bilateral multiple sclerosing hemangiomas of the lung

This report presents a case of bilateral multiple sclerosing hemangiomas of the lung in a 73-year-old woman. A computed tomography (CT) scan of the chest showed a total of three well-defined small nodules in the right and left lower lobes of the lung. Because malignant metastatic lung tumors were highly suspected, a wedge resection of the left lower lobe was performed to obtain a definitive diagnosis. Histopathologically, two tumors of the left lower lobe were composed of epithelial-like cuboidal cells covering the surface of papillary protrusions and sheets of round to polygonal cells underneath the epithelial-like cells. The final diagnosis was that both tumors were sclerosing hemangiomas. After surgery the residual lesion of the right lower lobe was carefully followed by chest CT. The size of the right lung nodule did not change over the course of 9 years, and no new lesion has emerged.
