Abstract

A 61-year-old male who originally visited a different hospital, underwent a health checkup in which multiple lung nodules were detected. Multiple well-defined small nodules were observed in both lungs, with lesions reaching the arteries. Metastatic lung cancer, with unknown origin, was suspected. A computed tomography-guided percutaneous lung biopsy was performed; however, a pathological diagnosis could not be established. Then the patient was referred to our hospital for surgical lung biopsy. Macroscopically, the nodule was dark-red in color and solid without a capsule. Microscopically, the nodule was composed of dilated vascular spaces lined by flattened bland cells. They were positive for CD34, but were negative for TTF-1, consistent with lesions of endothelial origin. Microscopic and immunohistochemical findings supported the diagnosis of multiple pulmonary cavernous hemangiomas. After diagnosis, the lesions were left untreated and thereafter showed no signs of deterioration.
