An abnormal shadow was noted in the thoracic region of a 54-year-old woman at a health checkup, and she was referred to our hospital. A neurogenic tumor was suspected based on the findings of the chest X-ray and computed tomography scan. Thoracoscopic tumorectomy was performed. The tumor surface was smooth with a reddish-dark reddish color, and capillary blood vessels showed marked growth around the tumor. The tumor was composed of medium or large blood vessels with a relatively thick vascular wall containing smooth muscle. On immunostaining, anti-CD34 antibody and Factor VIII were positive and D2-40 was negative. Based on these findings, the tumor was diagnosed as mediastinal venous hemangioma.Japanese Editorial Committee of Annals of Thoracic and Cardiovascular SurgeryJournal Articleapplication/pdfhttp://hdl.handle.net/2115/76529https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/76529/1/Yoshino-2012-Venous-hemangioma-of-the-posterior-.pdf2186-1005Annals of thoracic and cardiovascular surgery : official journal of the Association of Thoracic and Cardiovascular Surgeons of Asia1832472502012-05-20enginfo:pmid/22790999info:doi/10.5761/atcs.cr.11.01706https://creativecommons.org/licenses/by-nc-nd/4.0/publisher
